Problem with parameters in BirtExportReportDialog.js

system_migrated

I have been working for a couple of weeks in a web app using birt for reporting using v.2.5.2 and I had stumbled into a lot o problems to do simple things, needing to hack almost everything with scripting but this one is a bit too serious.

I have a report with a dataset parameters, to fetch them I have the same report parameters that just pass the values to the datasets but to integrate the viewer with our app we have done our own parameter form so I just set the params via <birt:params> under the viewer (html output, frameset mode) (birt:param tag don't work with EL expressions but thats another problem)

Anyway using birt:param creates hidden inputs to set the parameters wich is great but the BirtExportReportDialog.js doesn't process them so when I try to export the report I just get and empty report.

If there is not any other option I will modify the js to process the hidden inputs but it seems so obvious that params should be preserved (or at least give the option to do so) that I wanted to share it with you.

Fixed with the following code at "__exportAction" function<br />
<br />
var paramContainer = parent.document.getElementById("params_birtViewer");<br />
var oParams = paramContainer.getElementsByTagName('input');<br />
if( oParams ) {<br />
for( var i=0;i<oParams.length;i++ ) {<br />
//alert(oParams.name + "_" + birtUtility.getURLParameter(action,oParams.name));<br />
if (birtUtility.getURLParameter(action,oParams.name) == "")<br />
action = birtUtility.addURLParameter(action, oParams.name, oParams.value); <br />
}<br />
}
