Hi, While normally the id can be anything you want, in the case of indexing you are correct that it must be the same as the property.
The 'index out of bounds' is one of those classic problems with indexed properties since the list that holds the objects must be pre-initialized to hold them. If you search the archive you'll find a variety of solutions, one being using a hidden field and the size of the list to initialize in the reset method. The cooler (dare I say preferred? sure, except I haven't tried it) solution was posted a couple times by Aaron Bates which initializes on the fly. -john -----Original Message----- From: Sandeep Takhar [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 10, 2003 11:59 AM To: Struts Users Mailing List Subject: RE: <logic:iterate> and <html:text indexed="true"/> of course -I'm being stupid about the session scoped beans, however I haven't looked at the code and I don't know how the "indexed" property works with the "iterate" tag and I cannot extrapolate at the current moment either about what the code might look like. What I mean to say is: I don't know if indexed="true" works for anything other than forms. Should I guess, maybe you know. Are you sure you can name the "id" anything you want? It didn't seem to work for me until I named it the same as the property for whatever reason. Do you have a working sample? I suppose I should just try it. Also: if you are using the nested:iterate, can you include a jsp and have it used indexed="true" I wonder? sandeep --- Mark Galbreath <[EMAIL PROTECTED]> wrote: > Of course it works with session-scoped beans; that's > what an > ActionForn/DynaActionForm is by default. second, > "id" is complete arbitrary > - you can call any page object anything you want. > > Mark > > -----Original Message----- > From: Sandeep Takhar > [mailto:[EMAIL PROTECTED] > Sent: Tuesday, June 10, 2003 2:41 PM > To: Struts Users Mailing List > Subject: Re: <logic:iterate> and <html:text > indexed="true"/> > > > my small understanding on how to use this is as > follows: > > <logic:iterate name="form_name" > property="property_name" id="property_name"> > > <html:text property="some_property" indexed="true"> > > ok -- > > 1. form_name is the name of the form > 2. property_name is the name of the property and for > some reason the id="" also has to have the same name > 3. indexed="true" indicates that property is coming > from what we are iterating over. > 4.
