[Nuke-python] Second modal dialog

[Albert Rizov]

Hi, All

I try to open a child modal dialog box
class serverDialog(Dialog):
    ....

    def knobChanged(self, knob):
        ...
        if (knob==self._clientsListAdd):
            r = RenderNodesDialog(_gserverNodesDialogState, nuke.root())
            if (r.showModalDialog()==True):
                return

def showserverDialogSelected(nodes):

    groupContext = nuke.root()

    e = serverDialog(_gserverDialogState, groupContext, nodes)
    if (e.showModalDialog()==True):
        e.run()


but when I press "Ok" or "Cancel" button in a child window I have an 
message "I'm already executing something else"

are there any ideas what I'm doing wrong ?

Thanks
