This doesn't really address your suggestion specifically, but it might be worthwhile to write your own custom tag that assumes that it's nested within a logic:iterate and only evaluates it's body when it's not the last iteration. That way you could write something like this in your JSP:
<logic:iterate property="contacts" id="member" type="example.ui.busobj.Member" indexId="memberNumber"> <logic:write property="member.name"/><mylogic:notLastIteration>,</mylogic:notLastIter ation> </ logic:iterate> Which is more concise and communicates what you're doing more accurately, IMO. This tag shouldn't be hard to write...I'd take a crack at it, but I don't know if I'd be allowed by the company to post to the list...we still don't have a good policy regarding open source contributions :-( Now that I think about it, it might be nice to have a whole library of conditional tags for use within iterate: iterate:firstIteration iterate:lastIteration iterate:notFirstIteration iterate:notLastIteration iterate:even iterate:odd Although, on the other hand, if the iterate tag is going to be deprecated in favor of the JSTL forEach tag, then it may be better to target that. -- Tim Moore / Blackboard Inc. / Software Engineer 1899 L Street, NW / 5th Floor / Washington, DC 20036 Phone 202-463-4860 ext. 258 / Fax 202-463-4863 > -----Original Message----- > From: Heath Chiavettone [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, March 19, 2002 5:52 PM > To: '[EMAIL PROTECTED]' > Subject: Request for enhancement > > > I've found that I'm starting to get the following pattern > throughout my jsps. > > > > <bean:size property="contacts" id="numContacts"/> > > <% Integer lastContact = new Integer(numContacts.intValue() - 1); %> > > > > I'm mostly using this within an iterator to determine whether > I'm currently processing the last element of a collection as > is described below. > > > > <logic:iterate property="contacts" id="member" > type="example.ui.busobj.Member" indexId="memberNumber"> > > < logic:write > property="member.name"/><logic:lessThan > property="memberNumber" value="<%=lastContact.toString()%>">, > </logic:lessThan> > > </ logic:iterate> > > > > I was wondering if it makes sense to add an additional > attribute to the size tag which controls whether the value is > a true size, versus the index of the last element (i.e. one > based versus zero based)? > > > > Thanks for your feedback, > > Heath > > > > -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
