Birt 2.6.1: Hyperlink not working for iframe html report

Hi,<br />
<br />
We are testing with Birt 2.6.1 and seems like the hyperlink from label, dynamic data in the html report (inside iframe) are not working. The same hyperlinks work fine when the report is viewed in Birt viewer. Interestingly, the chart interactivity work fine, it's the text (label, dynamic text) hyperlink that's not working for html report in iframe. For ex, in birt viewer the hyperlink is shown as,<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
https://10.0.xx.xx/reports/frameset?__report=Dashboard/DashboardCGApp.rptdesign&__format=html&RP_tz=GMT-07:00&RP_st=2010-09-28+16:52:49.033&RP_sid=f5efbf35fd301947_62f9a-78b0&RP_et=2010-09-28+17:52:49.033&__overwrite=true&__locale=en_US&__svg=false&__designer=false&__pageoverflow=0&__masterpage=true
</pre>
<br />
<br />
whereas, in iframe it's shown as,<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
https://10.0.xx.xx/reports/frameset?__report=/opt/ps_manager/apps/reports/Dashboard/DashboardCGApp.rptdesign&__format=html&RP_tz=[America/Los_Angeles]&RP_st=[Tue+Sep+28+16:21:06+PDT+2010]&RP_sid=[f5efbf35fd301947_62f9a-78b0]&RP_et=[Tue+Sep+28+17:21:06+PDT+2010]&__overwrite=true
</pre>
<br />
The error I get in iframe is "RP_st" is not the right datetime. Note, the brackets "[xx]" in the url for each parameter value and the date time format is also different.<br />
<br />
This all used to work in Birt 2.6.0, but is broken in Birt 2.6.1. Anyone know of any change around this in 2.6.1?<br />
<br />
Thanks,<br />

Little more information - we have the following settings for html,<br />
<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
HTMLRenderOption renderOption = new HTMLRenderOption();

if(outputType.equals(REPORT_OUTPUT_TYPE.HTML.typeName())){
renderOption.setEmbeddable(true);
renderOption.setBaseImageURL(baseImageUrl);
renderOption.setImageDirectory(imageDirectory);
renderOption.setBaseURL(baseUrl+"/frameset");
renderOption.setSupportedImageFormats( "PNG;GIF;JPG;BMP;SWF");

}
</pre>
<br />
any issue there or need to change anything?

I just tried this with 2.6.1 and did not see the brackets.
Are you setting your own action handler?

Jason

No, we don't have any action handlers defined. Just putting mouse over the hyperlink shows the complete url with brackets in there (as I posted above). The exact same report in iframe works fine in 2.6.0. Anything else I can look for?

Can you run the code in a standalone app and produce the html output and look at the links? Also are the parameters multi-select parameters? Also try adding this to your options:

options.setActionHandler(new HTMLActionHandler());

Jason

I ran stand-alone in html (without iframe) and it's the same issue (parameter values have brackets in there). I also tried with the action handler option you suggested, but it's still the same problem. <br />
<br />
Looks like this problem is happening only if we use "IRunAndRenderTask" to run the report. If we run directly using Birt viewer we don't see the problem. Here is our code,<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
IRunAndRenderTask runRenderTask = null;
try {

IReportRunnable rptDesign = null;
rptDesign = this.birtEngine.openReportDesign(designFile.getAbsolutePath());

runRenderTask = this.birtEngine.createRunAndRenderTask(rptDesign);

HTMLRenderOption renderOption = new HTMLRenderOption();
renderOption.setOutputFileName(outputFile.getAbsolutePath());
renderOption.setOutputFormat(outputType);

if(outputType.equals(REPORT_OUTPUT_TYPE.HTML.typeName())){
renderOption.setEmbeddable(true);
renderOption.setBaseImageURL(baseImageUrl);
renderOption.setImageDirectory(imageDirectory);
renderOption.setBaseURL(baseUrl+"/frameset");
renderOption.setSupportedImageFormats( "PNG;GIF;JPG;BMP;SWF");
renderOption.setActionHandler(new HTMLActionHandler());

}
runRenderTask.setRenderOption(renderOption);

if(paramValues != null && paramValues.size() > 0){
runRenderTask.setParameterValues(paramValues);
}

runRenderTask.run();

</pre>

Any problem in the code?

Can you try this class with the attached report?

Attached report

Jason, the attached code worked fine. Looks like the problem comes in when you got a "Data Time" parameter, which is set to "Required" and then you bind it to the hyperlink. After I removed the "Is Required" attribute the hyperlink started working fine. So, the combination that breaks - html, text hyperlink, Date Time parameter, Is Required checked for the date time parameter.

Any change that might have caused this?

Thanks.

How are you setting the parameter?

Jason

The parameters are set inside initialize() method (javascript) of the parent report and passed on to the drill-down via parameter binding.

Can you try setting them in the API before you call the master report?

Jason

We use API only to retrieve parameters and execute the report. The parameter values for this report is required to be set in the report script itself. Would it be a problem setting the parameter value in the javascript of the report? Looks like the script engine issue? Is it?

If your parameter is required the engine is always going to complain if you do not set the parameter first (you should still be able to change it in the script).

Jason

We are passing the required parameter, but for some reason in Birt 2.6.1 the hyperlink has square brackets around the passed requirement parameter value (and the date format is different too). As soon as I remove isRequired, the hyperlink doesn't seem to have the square brackets - I posted the examples above in the thread.

This used to work fine in Birt 2.6.0 and prior. It's breaking in 2.6.1.

I did not see the example report. Can you build one or modify the one I posted to see if I can reproduce the issue?

Jason

Hey Jason,<br />
<br />
Just getting back to this issue. I see this being a problem in Birt 2.6.1 - do you know if there has been any fix regarding this? Just to summarize,<br />
<br />
1) I ran your stand-alone application with master.rptdesign. The Master reports generates fine, but the drill-down hyperlink still have issues. The parameter value in the drill-down hyperlink have square brackets,<br />

Vivek,<br />
<br />
This does appear to be a bug. The default HTMLActionHandler should be checking if the parameter is a list object. The viewer action handler does this. Could you log a bug for this? Just enter something like:<br />
ViewerHTMLActionHandler in the viewer handles processing parameters as a list whereas the report engine<br />
HTMLActionHandler does not. The HTMLActionHandler class needs to be updated.<br />
<br />
<br />
As a work around add your own action handler like the one I present below.<br />
Set it in your code like:<br />
options.setActionHandler(new MyActionHandler());<br />

Thanks Jason! I've filed a bug, https://bugs.eclipse.org/bugs/show_bug.cgi?id=335732

I also tried your new HTMLActionHandler and it seems to work fine. I'll continue to use this until the Birt code is fixed in next release.

Thanks again for the help.

<br />
Since, we are using Birt Viewer to display this rptdocument type I can not apply the custom action handler you'd suggested earlier. <br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
IRunTask task = this.birtEngine.createRunTask(rptDesign);
task.run(documentFile.getAbsolutePath());
</pre>
<br />
Is there a work-around to fix this issue?<br />
<br />
Thanks,<br />
-vivek

Any suggestion on this anyone?

Thanks.

Vivek,

You could still add your own action handler but it would be best to modify the viewer code for this. Any chance you could log another bug for this?

Jason

Thanks Jason. How would I add my own action handler for the viewer? I'm looking for a work around until this is fixed in the Birt itself. I've filed a new bug, https://bugs.eclipse.org/bugs/show_bug.cgi?id=341023

It would be great if I can get a workaround for now.

Thanks,
-vivek

In the beforeFactory do something like:

importPackage(Packages.my.example.pojo);
var mah = new MyActionHandler();
reportContext.getRenderOption().setOption("actionHandler",mah);

Jason

Hello Jason,

The reportContext.getRenderOption() is always coming up as null - I tried to put that in both beforeFactory and initialize. Is there anything else I need to do to get the render option to set action handler?

Thanks.

Jason,

Any input on how to get the renderOption from reportContext? getRenderOption is always returning null in the beforeFactory. Also, is there a way to patch Birt 2.6.1? Apparently, this bug is fixed in Birt 2.6.2, but we can not update the whole Birt at this time so simply changing a file (or a jar) would be preferable.

Thanks,
-vivek

Vivek,

How are you running the report? I run the report in the viewer with the code sample I posted earlier and it works fine.

Jason

Jason,<br />
<br />
The report gets run by the APIs,<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
task = this.birtEngine.createRunTask(rptDesign);
..
task.run(documentFile.getAbsolutePath());
</pre>
<br />
This generates a link, for ex.,<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
https://10.0.x.xx/reports/frameset?__document=scheduled/rptName_04062011055604980-3.rptdocument
</pre>
<br />
The problem comes when we click on the link to run the report in the Birt Viewer - the drill-down in the rendered report throw the NPE.<br />
<br />
Rendering directly on Birt Viewer (without API) or generating other format (pdf) from API work fine, it's the generating rptdocument from APIs is causing problem - and this is our most used as we use this to email the link to the user.<br />
<br />
Hope this helps understanding the issue. So, I'm trying to see what workaround can be used to solve this.<br />
<br />
Thanks,<br />
-vivek

Vivek,

Maybe I am missing something but if you are running the apis why not just create your own action handler and set it in the api like:

IRenderOption options = new RenderOption();
options.setOutputFormat("html");
long pgcnt = document.getPageCount();
System.out.println(pgcnt);
//options.setOutputStream(arg0)
options.setOutputFileName("output/resample/mcb.html");

if( options.getOutputFormat().equalsIgnoreCase("html")){
HTMLRenderOption htmlOptions = new HTMLRenderOption( options);
htmlOptions.setImageDirectory("output/image");
htmlOptions.setHtmlPagination(false);
//set this if you want your image source url to be altered
htmlOptions.setBaseImageURL("http://myhos/prependme?image=");
htmlOptions.setHtmlRtLFlag(false);
htmlOptions.setEmbeddable(false);
}else if( options.getOutputFormat().equalsIgnoreCase("pdf") ){

PDFRenderOption pdfOptions = new PDFRenderOption( options );
//options.setOutputStream(arg0)
pdfOptions.setOption( IPDFRenderOption.FIT_TO_PAGE, new Boolean(true) );
pdfOptions.setOption( IPDFRenderOption.PAGEBREAK_PAGINATION_ONLY, new Boolean(true) );
pdfOptions.setOption(IPDFRenderOption.PAGE_OVERFLOW, IPDFRenderOption.FIT_TO_PAGE_SIZE);

}
options.setActionHandler(new MyActionHandler());

IRenderTask task = engine.createRenderTask(document)

Where MyActionHandler is your class.

Jason

Ok I went back an re-read the thread and you are setting it in the api and then forwarding the rptdocument to the viewer. I am not certain if it will work but can you try to move the script to the beforeRender event?

Jason

Thanks Jason. Yes, I tried it in beforeRender, but the script doesn't gets executed there (I also tried it in initialize as it gets run before presentation phase also, but that didn't work either). This all used to work in Birt 2.3. I'm not sure if this is fixed in 2.6.2 or if we got any other workaround for this.
