Okay, yes the actual business process is not very well explained. Probably I should have used generic object names, but since it's started:
I have a bunch of "story" objects. Each story object can belong to 0 or more groups. The functionality of this page is to show the user which groups their stories belong to as well as to change the groups to which each story belongs. So the user can page through the list of her stories (generated through the search bean, which is actually an attribute on the ActionForm Bean (submitToGroupForm)). For each list of 10 stories, the submitToGroupForm sets up a map called "existingGroups" which contains a String array of the group id's associated with each story. "availableGroups" is an array of String group id's put into actionFormBean which contains all the groups the user has permission to access. So, in addition to the regular info on each story (title, id, plus the tile "storyDetailswithBlurb.jsp"), the generated page is a matrix of checkboxes: One row of "availableGroups" checkboxes for each story. The idea was to use the map on the actionForm to receive changes to groups, with the key of the map being the storyId, and the value being the array of groups Id's that were checked off for each story. Then my Action will pass that info off to a bean that will do the reassignment. -----Original Message----- From: James Mitchell [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 05, 2003 4:22 AM To: 'Struts Users Mailing List' Subject: RE: Accepting arrays as values in mapped-backed ActionForms Ok, I've had time to look over your notes. I may be missing some pieces to the puzzle here. If I understand you correctly, you've got a bean (searchBean) that has a List of Story beans, each with id and title. You have a formbean (submitToGroupForm) that returns a Map of Groups (getExistingGroups) keyed off of the id from an iteration of the first bean (searchBean). Is this correct so far? Which bean is the form associated with this action? (I am assuming submitToGroupForm) Why do you iterate over the formbean, then iterate over a field on that bean? Can you post more details on what you are wanting to accomplish here? -- James Mitchell Web Developer/Struts Evangelist http://jakarta.apache.org/struts/ "People demand freedom of speech to make up for the freedom of thought which they avoid." - Soren Aabye Kierkegaard (1813-1855) > -----Original Message----- > From: James Mitchell [mailto:[EMAIL PROTECTED] > Sent: Tuesday, March 04, 2003 6:38 PM > To: 'Struts Users Mailing List' > Subject: RE: Accepting arrays as values in mapped-backed ActionForms > > > John, sorry for not getting back sooner.
