generate on OnSaveDone

Hi all,

I am generating a page on the click of Finish Button.But My problem here is:

1.Yes it's possible, but I'm not sure if it is really advisable.
2. Basically onSaveDone event handler that does a callServer() which generates the html - however, since this is asynchronous and happens after the save has been completed - what do you do if the generation fails?
3.You could send an alert to the user - but the widow might not still be open so they won't see it. If they do see it - might it not be more confusing than helpful?Is It would probably be better to do something like this as part of a workflow task.

So, My Idea is to generate the html as a part of the workflow,But our requirement is that "If the user clicks Finish Button at the backend html should be generated and should be deployed to test environment".So, I have to consider the case:
1.If the genertion step fails after the workflow started, then the workflow sits there.without going to deployment step and is there any way that i suggest the user that generation is failed?

Thanks in advance

You need to push back on the qualifications of the "requirement" - the page generation should be done as part of a workflow - if you want, perhaps have a simple "DCR Saved" workflow along with a bigger "Review" workflow - the first would could be fired off of tt_data command, take care of generating the page(s) from the DCR(s) and deploying them to wherever you want - since it is within the context of a workflow you should be able to handle error situations more correctly.

The user may have to go through some additional steps to initiate the workflow after saving the DCR, but sometimes a little bit of training is better than a bunch of questionable code.

You *must* have a method to calculate the generated page from the DCR. I helped on a site that had 300 files in .../data/ and folders everywhere. DCR named foo and generated files named bar. Autogeneration of that is pretty much impossible (without a lot of gymnastics)

Thanks for the responses.

I have a function to capture the result back to js as below:
my ${js} .= 'parent.getScriptFrame().getStatus("' . ${Success} . '" );' . "\n";
print CGI::header(), CGI::start_html( -script => ${js} ), CGI::end_html();

But the status of success does not display a message or alert if the generation is failed on the click of Finish.As I have handled in OnSaveDone.

And My Requirement is that I have only Finish Button renamed as save and generate.I have hidden all other save,saveas buttons.So On the click of Finish Button Html should be generated and deployed.

1. OnSaveValid-->Validations of dates and remaining stuff.After Validations As for autonaming in the onsavelid i have

var publishdate=new Date(PublishDate.getValue());
var expirationdate=new Date(ExpirationDate.getValue());
if((publishdate!="NaN")&&(expirationdate!="NaN"))
{
if(publishdate>expirationdate)
{
alert("Expiration Date Must be after Publish Date");
return false;
}
else
{
dcrName=IWDatacapture.getItem("/Article/AutogenerateName").getValue();

IWDCRInfo.setDCRName(dcrName, checkStatus);
}
and in the checkstatus function i called IWDatacapture.save if DCR already exists.and in the onsavedone i am using iwft_compile.ipl? so, I wil gain have the same problem that the initiation of the workflow might fail as I am handling in the OnsaveDone..

Any help is appreciated..How can I hanle this?
Thanks in advance

True, if you attempt to initiate the workflow via the callServer process you have the same problem of not being able to provide feedback if the instantiation of the workflow fails. On the other hand, if you configure the workflow for tt_data, the user should be prompted to initiate the workflow after saving (and closing?) the DCR - and then you have instant feedback if the workflow fails to instantiate plus the ability to build in feedback in the workflow process if any of the steps within the process fail.

If you insist on trying to satisfy the questionable requirements of performing the page generation and/or workflow instantiation as part of an asynchronous process that takes place after the DCR has finished being saved, and when you are not guaranteed to have a UI in front of the user - well, that's your choice. I would present the pros & cons of the approaches to the customer and let them make a (hopefully) informed decision.

Hi I have a similar requirment. Were you able to generate an output file via FormApi - I have an identical requirement and would appreciate any tips/help.

I'm up to this point and need some help tp proceed
[PHP]

function init(){

// Register a function to handle Save.
IWEventRegistry.addFormHandler("onSaveDone", saveDone);

}

function saveDone(){

//var result;

var dcrName = IWDCRInfo.getDCRName();
var outputFile = dcrname + "\n.html";

var tplName = IWPageGeneration.getValidPresentationTemplates();

IWPageGeneration.setPresentationTemplate(tplName);

var page IWPageGeneration.setOutputFile(outputFile);

return result;

}
// Call the init routine onLoad
IWEventRegistry.addFormHandler("onFormInit", init);

[/PHP]

Hi Windy,

One good Approach is to hable that in Workflow beacuse
1.Yes it's possible, but I'm not sure if it is really advisable.
2. Basically onSaveDone event handler that does a callServer() which generates the html - however, since this is asynchronous and happens after the save has been completed - what do you do if the generation fails?
3.You could send an alert to the user - but the widow might not still be open so they won't see it. If they do see it - might it not be more confusing than helpful?Is It would probably be better to do something like this as part of a workflow task.

So what u can do is another option is:

in onsavedonehandler u can call an ipl and run iwgen command if the result of execution is null then in the window a message saying that page generation is successful and if it is failed give them message it is failed.

url="http://"+server+"/iw-bin/iw_cgi_wrapper.cgi/generate_page.ipl";
url=url+"?workarea="+workarea;
url=url+"&templatepath="+templatepath;
url=url+"&recordvpath="+recordvpath;
url=url+"&outputFile="+outputFile;
window.open(url);

Thanks for your response. Could you send me code snippets from generate_page.ipl? Thanks

#!D:\Interwoven\TeamSite/iw-perl/bin/iwperl
use TeamSite::CGI_lite;
use TeamSite::Config;
my $iwhome = TeamSite::Config::iwgethome();
my $iwmount = TeamSite::Config::iwgetmount();
use CGI;

#Turn buffering off.
$| = 1;

my $IWGEN = $iwhome . "/bin/iwgen";

my $in = new CGI;
my $workarea = $in->param('workarea');
my $templatepath  = $in->param('templatepath'); 
my $recordvpath = $in->param('recordvpath');
my $outputFile  = $in->param('outputFile');

my $genfile = $iwmount . $workarea . $outputFile;

my $Success = "";
my $cmd = qq[$IWGEN -t "$templatepath" -r "$recordvpath" "$genfile"];
$Success = `$command 2>&1`;  
chomp($Success);
debug($Success);
$Success = CGI::escape($Success); 

###     Close the script
exit;

You can add some basic cgi in here.The avove code just generates a html.You can CGI to give the user a message regarding page generation success or failure
