(of other portlets) to get lost

Description:
The Portlet Application Manager uses the TreeControl taglib for navigation of the
Application Tree.
On first usage, the TreeControl is filled with Action URLs for each of the tree nodes
to render.
Because these are thereafter cached, portlet render parameters (which are stored in
the saved Portlet URL) are frozen to this initialization time.
Selecting a TreeControl node on a page which also contains other portlets therefore
results in losing any changed render state (parameter s) of those portlets.
Because by default SesionNavigationalState is used in J2, window and portlet mode do
carry over, but if PathNavigationState would be used, those settings also would be
lost.
In general: Portlet URLs may *never* be cached. Saving render parameters in the
Portlet Session would fix this, but would not be portable according to the JSR-168
specification (another serious limitation of the spec I think).
Solution: don't cache Portlet URLs in the TreeControl taglib component.
