MWS different behaviour in debug mode when using portlet include

Hello,

we have a portlet application which makes use of the portlet include component. Portlet A contains Portlet B and Portlet C. When submitting the data of the included portlets (asynchronously) from portlet A, sometimes the initialize() method of Portlet A is called. Often this happens after several submits. When MWS is started normaly this never seems to happen, only when MWS is started in debug mode. Is there a different MWS behaviour in debug mode? Why is initialize() called? Is there a page bean cleanup on the server side? May it be a performance problem in debug mode?

Environment:
MWS 7.1.3

Thanks,
Robert

What you have described would not be the expected behavior. It should work the same in debug mode.
