Added: portals-bridges/common/src/java/org/apache/portals/bridges/common
ScriptRuntimeData.java ScriptPostProcess.java
Log:
Cleanup and improvement of the PERL portlet
--> Added navigation support for Form actions, hrefs to other perl scripts
--> Normalized action handling for the portlet.
-- >Moved some utility functions into the portals-bridges common package
since the PHP portlet uses some of the same functionality
