Downloading PDF File generated by interactive form element

[Former Member]

Hi,

I am generating a PDF form using interactiveform element and displaying in a separate view. Is it possible to download the same generated form instead of displaying in view?

Please sugest me on this.

Thanks,

Raz

Hi Raz,

Try this...

1. Create a context attribute(res) of type com.sap.ide.webdynpro.uielementdefinitions.Resource

2. Insert a file download ui control and bind the property resource to the above attribute

3. you must have defined a pdfSource of type byte[], using that populate the 'res' attribute

IWDResource res = WDResourceFactory.createResource(wdContext.currentContextElement().getPdfSource(),"",WDWebResourceType.PDF);
    wdContext.currentContextElement().setRes(res);

Hi Aarthi,

The PDF Source is of type binary, can you please suggest me how to convert it to byte array?

Thanks,

Hi,

Use this following code in any button action, then you will be seen a popup window to download the pdf from resource path

Hope

IWDWindow window = wdComponentAPI.getWindowManager().createNonModalExternalWindow(resource.getUrl(WDFileDownloadBehaviour.ALLOW_SAVE.ordinal()),

resource.getResourceName());

window.show();

Hope you have pdf in IWDCachedwebResource

Hi Aarthi,

Thanks for your patience. I am getting the fallowing runtime error when I am executing. I wrote the code in wdinit() specified by you.

pdf might not be generated in the init method itself.

try to invoke the mentioned code in an action, after the pdf is generated.
