I have recently upgraded to Maple 11 and I have been having a recurrent problem when I run documents with embedded plots that use "fieldplot". These documents functioned perfect using Maple 10.
My problem is that I get the error "Invalid Plot Structure" when I run from a button the code
SetProperty('Plot0', 'value', plotxy):
for the first time after the document is first opened. If the code is run again (after acknowledging the error, and without closing out the document), the field plot will be displayed as it should.
The error ONLY occurs during the first compiliation.
The error doesn't occur if for example I use:
and the problem occurs even if I cut and paste the Maple help fieldplot example into the code.
