$Log: SelectWMCPortletPerform.java,v $
Revision 1.5 2006/11/06 13:53:54 poth
bug fix - using correct map portlet ID for accessing WMC
Revision 1.4 2006/10/12 15:46:19 poth
adaption required to avoid allocating larger amounts of memory for each user session when using several WMC documents
Revision 1.3 2006/08/06 19:52:54 poth
support for taking bbox from the previous context into the new one added
Revision 1.2 2006/06/06 19:49:25 poth
handling of mapmodel changed - it now will be available for each MapWindowPortlet through the session
Revision 1.1 2006/06/06 19:02:00 poth
initial upload of SelectWMC portlet
