Operator's popup is not redrawn when chaging some value.
Test script: http://www.pasteall.org/19842/python
Click bool prop - UI doesn't updated.
Thanks in advance!
The redraws are all OK - but the issue is that our menu popups are only generated once, with a fixed region boundbox and static defined options.
What you want is a persistent panel with dynamic amounts of buttons and settings. For such cases popups shouldn't be used - and not will become available either.
I will put on my short term todo: general option for operator buttons to draw its properties as permanent set of options. That's what we intended with Blender design spec to make a non-modal parellel working UI :)
