Problem with custom tag

Question

I have written a custom tag that I am having problems with. It works on some machines, but not on others. I have a page that uses many 'standard' tags. I have correctly set the URI etc, because all of my other tags work. However, on some machines, my custom tag gives me an error:
attribute does not support request time values
I'm assuming that I have the correct versions of standard.jar etc because all of the regular jstl 1.1 tags work. It is just my custom tag that throws an error.
here is the .tld for my tag:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN" "http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd">
<taglib>
     <tlib-version>1.1.2</tlib-version>
     <jsp-version>1.2</jsp-version>
     <short-name>My custom tag</short-name>
     <uri>http://my.custom/tags</uri>
     <tag>
          <name>breadcrumb</name>
          <tag-class>tag.BreadcrumbTag</tag-class>
          <body-content>JSP</body-content>
          <attribute>
               <name>breadcrumbs</name>
               <required>true</required>
               <rtexprvalue>false</rtexprvalue>
               <description>Pass in the list of Breadcrumbs containing the actual information
about what tags need to be rendered on the page.</description>
          </attribute>
     </tag>
</taglib>
Any thoughts/help greatly appreciated...

I encountered the same problem in our environment. I did the same thing as
          James. Simply re-initialize all variables in the do end tag.
          Also, with the nested tags you use you may also need to implement cloneable
          in the inner tag if the outer tag keeps references to all the inner tag
          instances.
          For instance if the outer tag kept a vector of references to the inner tag,
          then you would need to use clone() on the inner tag before adding it to the
          vector.
