I'm currently using R17.048.
Someone can confirm create a ScrollGroupBegin and call a LayoutFlushGroup into this group make C4D crash.
If I only do LayoutFLushGroup no crash
If I only do LayoutChanged no crash
If I do LayoutFLushGroup  + LayoutChanged = crash

import c4d
class Dialog(c4d.gui.GeDialog) :
  
    def CreateLayout(self) :
  
        flags = c4d.SCROLLGROUP_HORIZ | c4d.SCROLLGROUP_VERT
        if self.ScrollGroupBegin(1001, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT, flags, 100, 100) :
            self.AddButton(1000, c4d.BFH_SCALEFIT | c4d.BFV_SCALEFIT,100,50 , "Make it crash")
            self.GroupEnd()  
  
        return True
  
    def Command(self, id, msg) :
        if id == 1000:
            self.LayoutFlushGroup(1001)
            self.LayoutChanged(1001)
        return True
  
dlg = Dialog()
dlg.Open(c4d.DLG_TYPE_ASYNC)

Hello,

it looks like the issue is related to the fact that the scroll group does not include a sub-group. Typically a scroll group includes another group. And this sub-group then hosts the actual elements (see this C++ example).

So it will work if you include a sub-group and flush only this sub-group (instead of flushing the scroll group itself)

Best wishes,
Sebastian

Sorry for the late reply. 
Thanks you for your message

All is working as you described (but maybe it can be good to have something similar written in the sdk for other peoples ^^)
