Issue with custom print.html, bug in 13.0?

[mathias]

EDIT: oh man, i just noticed that we apparently had added the v=1 parameter to avoid caching the print html. I am sorry, carry on as you were...

Hi, i just moved our custom print.html page to our latest version of our project, and i don't think it works properly in 13.0.

I basically do what you have suggested in other threads here previously, I get the printframe.html out, i got it from

smartgwtpro-13.0p/lib/smartgwtpro/com/smartclient/public/sc/system/helpers

, and i have a row in my loadingpage that changes the url like this:

<script>isc.PrintCanvas.addProperties({printFrameURL: "ns/print.html});</script>

I then just call Canvas.showPrintPreview(grid).


However, in the latest smartgwt version (i just downloaded 2022-09-21), nothing happens and i get this in the log:

Printing:Print canvas with ID:undefined failed to render correctly.

I looked at PrintFrame.html, and maybe it's an issue with the url params?

IN the old smartgwt(12.1), the url when printpreview is called is this:

http://....../PrintFrame.html?id=isc_PrintCanvas_0&title=MyTitle

but in 13.0 it is:

http:/...PrintFrame.html?v=1?id=isc_PrintCanvas_0&title=MyTitle

As you can see, there's now a "v" as the first url parameter, so there are multiple '?' in the url which screws up the parsing of the url params.

If i go into the printframe.html and hard-code line 174 from
window.controllerCanvas = "params.id";
to
window.controllerCanvas = "isc_PrintCanvas_0";

it works.


Seems like something that requires a fix, but is there anything i can do on my end in java code in the meantime?

Pointers appreciated, cheers

Thanks for the report - we've fixed this for tomorrow's builds.

The problem was that internal logic was doing this.printFrameURL + "? ...", but your printFrameURL already has params (or did, when you first posted it :) )

yeah, i took it away since i was the one that had added it, didn't want to confuse you. Thanks!
