Subject Displaying portlet in decorator
Date Wed, 13 Apr 2005 17:16:21 GMT
Hi,

Is there any way to display a portlet in the decorator built part of
the page (the portlet is not included in a psml file)?

This is what I do in my decorator file :
---
PageImpl searchPage = (PageImpl) rootFolder.getPage("search.psml");

FragmentImpl searchFragment = (FragmentImpl)
searchPage.getFragmentById("simple-search-1");

jetspeed.include(searchFragment);
---
First I locate psml file (search.psml) with portlet in it
(fragment's id is 'simple-search-1'). Finally, I use 'include' on
fragment I have found. The 'include' function is taken from
JetspeedPowerTool class.

After all that I am able to see my search portlet just between some
menus my decorator has built, but... portlets from currnet psml file
cause some seriuos errors during rendering.  

The stack trace is (sorry for pasting huge fragment):

I am using Jetspeed-2-M1 and JBoss4.0.1sp1.

Any suggestions will be appreciated.

Thank you in advance.
