[TYPO3-mvc] Potential problem when using two plugins on same page

[Robert Schneider]

Hi,

I have an extbase/fluid FE extension with two plugins. On a page I use 
both plugins. The page is accessed by an action (user submit something 
and gets to this page). Both plugins show some session data, i.e. they 
have the same base of data.

Is is possible that I get an timing issue if the second processed plugin 
modifies the session data? So that the first plugin shows some old data 
and the second show the new data?

If so, could I change or control the flow?

Regards,
Robert
