Grtting an Error while using forEach tag
Dear All,
I am using forEach tag for iterating over an ArrayList present in
the session scope. The code I have used is
<core:forEach var="image" items="${TREE-IMAGES}">
------
------
</core:forEach>
When i execute this page I get the following error
An error occurred while evaluating custom action attribute "items" with
value "${TREE-IMAGES}": Attempt to coerce a value of type
"java.util.ArrayList" to type "java.lang.Long" (null
But if I get the value and store it in a different name the forEach
tag works properly. The changed code is
<%
java.util.ArrayList list =
(java.util.ArrayList)pageContext.findAttribute("TREE-IMAGES");
session.setAttribute("IMAGES",list); %>
<core:forEach var="image" items="IMAGES">
-----
-----
</core:forEach>
This works properly. Will there be a problem if there is a - in the
variabe name or have i misunderstood something.
Thanks
Shanmugam PL
