RE: logic:iterate multiple collections
A related question, so I thought I'll post it to this thread. The data structure I use is a HashMap, whose values are other HashMaps. Like so: OuterMap OuterKey1: InnerMap1 InnerKey11: Value11 InnerKey12: Value12 OuterKey2: InnerMap2 InnerKey21: Value21 InnerKey22: Value22 I'm trying to nest two logic:iterate tags to print out the keys in the outer map and the values in the inner Map. What I'm trying to do is something like this: logic:iterate id=myOuterMap name=myForm property=myOuterMap tr tdbean:write name=myOuterMap property=key//td logic:iterate id=myInnerMap name=myForm property=myInnerMap tdbean:write name=myInnerMap property=value//td /logic:iterate /tr /logic:iterate This has a problem, because, it needs the innerMap attribute set in the request - however, this always gets the same value, probably because of the way I'm setting it in my Action. 1) I probably need a list of innerMaps in my form, but I'm not sure how to do this. 2) If I try to print the value using the outerMap alone, like so, tdbean:write name=MyOuterMap property=value//td I'm not sure how I can format this in the way that only the values are seen. Does anyone have any pointers?

RE: logic:iterate multiple collections
Thanks! That worked, and is also much easier to understand. This is probably a newbie question: How / when does one choose between using JSTL / Struts Tags? Is there any reason to choose Struts tags over JSTL?

Re: logic:iterate multiple collections
See http://struts.apache.org/faqs/struts-el.html. It includes a list of Struts tags whose functionality is covered by the JSTL. On 5/24/05, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: Thanks!

logic:iterate multiple collections
Hi all, Let's say I have two collections, A, and B. Is there a way to iterate over multiple collections with something like logic:iterate? i.e logic:iterate ${rowA.name} ${rowB.value} /logic:iterate -- Titus Barik ([EMAIL PROTECTED]) http://www.barik.net - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
