Hello again,
well, I have digged into the WPainter class, and the class is unable to
retrieve the image size: size.x() and size.y() are 0, so the exception in
line 134 is thrown.
Now the value of the fileName argument is
fileName = "C:\Users\JHLEGA~1\AppData\Local\Temp\wt-5826.tmp"
which is the spoolFileName given by WFileUpload's corresponding method.
Any hints?
Thanks,
JON HAITZ

Dear Koen,
thanks again for your early answer.
As for the m_SpoolFileName, it's the spoolFileName given by WFileUpload's
corresponding method. Even hard-coding the original filename (including the
path and extension) instead the spool filename the exception I get is just
the same.
According to the call stack (attached, even if I guess it does not help
much at this point), the WebSession, the Application and all the widgets
contained in are being destroyed. Indeed, the destroyer of my widget
container (ImageUploadWidgetContainer) is being called when trying to use
the mentioned option.
This is strange. Any hints?
Thanks again,
JON HAITZ
