hi,

i wrote a portlet-struts application on jboss-portal 2.6 about 6 months ago (a phone book). now i try to add some new features (without yet changing the configs) and face the following problem. on the first page (/index) i use the action-class to pass two array-lists to the jsp (building_list and org_list). when a search is started i search a database for the given parameters and return another array-list (ausgabe) to the action class. there i use request.setAttribute(...) to pass it on to the second page (/input). my problem is that the first two array-lists are really passed on from the action-class but the third one isn't. the funny thing is that 6 months ago all three array-lists were passed on correctly.
