Hi! I've got a strange issue with modal dialogs and I can't find a workaround. Paste the following code into the Script Manager and run it. The dialog should pop up twice.

  
import c4d
  
class SubmitSummaryDialog(c4d.gui.GeDialog) :

        return True
  
s = SubmitSummaryDialog()
s.put("hello")
s.Open()
s.Open()

It does, but the second one has no content!

First:  Second:

How can I fix this?

Thanks! (PS: R16.050)

Don't you need to create a unique class instance for each dialog you open?

s = SubmitSummaryDialog()
s.put("hello")
s.Open()

s2 = SubmitSummaryDialog()
s2.put("hello")
s2.Open()

Hey Scott,

You're right, that works! And I actually tried that already (that's why there is a copy() method in the
class)! But when I did, the function that was opening the dialog was still referencing the original dialog
instance (not the second, new instance). After I sorted that out, it works.

Thanks for the hint!

Cheers,
