Nested recursion does not recurse!
Hi, everyone, Am I crazy? I have been trying to get recursion to work using Arron's examples at keyboardmonkey and it absolutely will not recurse. It just repeats the very first element. Here's what I get displayed in my HTML results: -- USA - productTree ALABAMA - productTree.treeNodes[0] ALABAMA - productTree.treeNodes[0] ALABAMA - productTree.treeNodes[0] ALABAMA - productTree.treeNodes[0] -- Why is the same nested level repeated over and over? Note: my Form class returns Object arrays (i.e. TreeNode[] getTreeNodes()). Here's productNode.jsp: -- %@ taglib uri=/WEB-INF/tld/struts-nested.tld prefix=nested % nested:root nested:write property=label / - nested:writeNesting/br nested:equal property=isExpanded value=true nested:iterate id=node property=treeNodes jsp:include page=productNode.jsp / /nested:iterate /nested:equal /nested:root -- And the relevant code from product.jsp: -- nested:form action=submitJob.do method=POST . !-- Begin Product Tree -- nested:nest property=productTree jsp:include page=../product/productNode.jsp/ /nested:nest !-- End Product Tree -- /nested:form -- I should note that I set isExpanded (i.e. showChildren) to true for the very top-level element. I do have other (non-nested) Struts tags included in this page outside the ProductTree code. I'm on Tomcat 4.1.18, RedHat 8.0, Struts 1.1 rc2, jdk 1.3.1_07. Thanks!

Re: Nested recursion does not recurse!
Are you sure you want to include a page that has a form in it? nested:form, nested:nest and nested:iterate all start a new root element that nested will use. Whenever you do a jsp:include always do a nested:root at the beginning if you are using nested tags. sandeep --- Chris Hatton [EMAIL PROTECTED] wrote: Hi, everyone, Am I crazy?

Re: Nested recursion does not recurse!
All the markup seems fine. This is very indicative of the older Struts on the newer tomcat. Double check the version of Struts. 4.1.x was broken with recursion and such things, but it's fixed for RC2. As a last resort, try this jar... keyboardmonkey.com/downloads/km-nested-v2.03.jar ...throw it into the WEB-INF/lib directory. It has just the new nested tags, should show if it's the tag version being out of whack. Sandeep: The new version of the tags above, doesn't need a nested:root for included pages. Now all the tags now use the request object to hold their references, all the nested tags just look for that rather than look at the current JSP's tag layout. It just means that as long as the nested structure is started (nested:form, nested:root, any nested parent tag), any include file can just mark up child tags like normal and it should work. I probably wouldn't have done this on purpose, but using the request object use was the only way I could get the new tomcat working for some reason. Arron.
