s:if tag syntax help needed
Hi
I'm iterating over a List<Element> with <s:iterator status="status"
value="structure.elements"> and I want to test that the element returned is
an instanceof a specific type of element, so I've tried with
<s:if test="%{<s:property/> instanceof StringElement}">
<s:if test="%{structure.elements[#status.index] instanceof StringElement}">
<s:if test="structure.elements[%{#status.index}] instanceof StringElement}">
none of which work. Could some kind soul show me the correct syntax for
this?
Regards

Sorry about the delay in replying, but it's a 6 day Easter break in my
locale. Anyway, using the fully qualified class name solves the issue;
<s:if test="%{#element instanceof com.myapp.mypackage.StringElement}">

The problem might not be with instanceof but rather StringElement. Did
you try a fully qualified classname?

is the closest you listed. Try that one (or replace
"structure.elements[#status.index]" with "top") but with both package
and classname for StringElement.

Im not sure that you can use it (instanceof).
Why dont you do that in the action class, creating a new collection!
