Button program in Error after running script

[Theo Kusters]

Hi,

I have a button that runs a validation program and, if the grid filters are validated, a script is run through behaviours. This script creates a client generated PDF through pdfMake.

This only works once.
After the pdf is created, the grid isn't responding to new filter settings anymore
If I click the button again, my validation program fails:

CPF9898 - Expected a colon after a key.

VVCALL[VVCALL]VALLOC001R[VALLOC001R]VALLOC001R[INITIALIZE]JSON{JSON_PAR}[json_parse]JSON{JSON_PAR}[NEXTARRAY]JSON{JSON_PAR}[NEXTVALUE]JSON{JSON_PAR}[json_parse]JSON{JSON_PAR}[NEXTOBJECT] 

Kind regards,
Theo

Hi Theo,

When you say your button runs a validation program do you mean you have a button that calls an RPG program based on "EXNABBTN"? Then on success, you have a script that is run which creates a PDF

Thanks

Hi Johnny,
Yes, thats correct.

Ok, so if you comment out your script that creates the PDF does the call to your program via the button click then work every time?

Thanks

This is the last part my my script now, the rest is unchanged.
Now the grid keeps working

 // Generate the Pdf
//
// pdfDocGenerator = pdfMake.createPdf(docDefinition);
// pdfDocGenerator.getDataUrl().then(function (dataUrl) {
// update the appvar url so that the viewer shows the new
// pdf report
// setAppVar('urlPdf', dataUrl);
// Valence.common.util.Helper.destroyLoadMask();
// success();
// }, failure);
Valence.common.util.Helper.destroyLoadMask();
success();
}, failure);
}, failure);
}, failure);

All app variables are passed down on each call and since you were placing the data URL in an app var that would be passed down making the request too large. I would suggest instead of doing the getDataUrl using the download method directly from pdfMake.

[Johnny Major]

If you're using the 'getDataUrl' so you can view the PDF in a URL Widget you could name that widget and pull it in and set the source manually.

For example, I have a URL widget in my application that is named "pdfUrlWidget" and I am getting that widget and calling its setSource method passing the dataUrl.

pdfDocGenerator.getDataUrl().then(function (dataUrl) {
    // get the URL Widget that is named "pdfURLWidget"
    //  and set the source with the data URL
    //
    var pdfUrlWidget = getWidget('pdfUrlWidget');
    pdfUrlWidget.setSource(dataUrl);

    Valence.common.util.Helper.destroyLoadMask();
    success();
}, failure);
