Struts2 tags loops
Hi,
Is there any way to iterate over an integer range with the <s:iterate/> tag?
I have an integer property (pageCount) in my action and I want to
print all the integer values between 1 and this property in my JSP.
cheers

This is in no way the case.
What is disallowed in 2.0.11 is el expressions as struts tag attributes.

You can achieve what you expect with the following code in your JSP:
<s:bean name="org.apache.struts2.util.Counter" var="counter">
<s:param name="last" value="%{pageCount}" />
</s:bean>
<s:iterator value="#counter">
<s:property />
</s:iterator>
--- OR --- you can publish a Counter directly from your java code
public class TestIterator2 extends ActionSupport {
Counter counter;
public Counter getCounter() {
return counter;
}
@Override
public String execute() throws Exception {
counter = new Counter();
counter.setFirst(0);
counter.setLast(40);
return SUCCESS;
}
}
that can be iterated from your JSP like this:
<s:iterator value="counter">
<s:property />
</s:iterator>

That limitation is only for struts tags, for example <s:property
value="${somevalue}"/>, otherwise you shouldn't have problems with JSTL. I
haven't run into any on 2.0.11.

Nop. Neither way works.
<s:iterate value="pageCount">
<s:property />
</s:iterate>
This has a single iteration, and the value outputted is the value of
the variable (10 for example).
The <c:forEach> jstl tag, as well as all other jstl tags, is not
allowed in struts 2.0.11, afaik.

Not that I'm aware of; easier to use <c:forEach.../> IMO.
