Question

I would like to create a really simple tag parameterized with a collections’ ids something like the following:

<s:url action="theaction" namespace="/" includeParams="all" id="histURL">
 <s:param name="sources" value="sources.{id}"></s:param>
</s:url>
${histURL}

If I have say three Source objects defined in my Action class, having ids 1,2 and 3 then I assume, the histURL output will be sg like:

http://localhost:8080/myproject/theaction&sources=1&sources=2&sources=3

But it does not work, it displays:

http://localhost:8080/myproject/theaction

Another hint:

<s:url action="theaction" namespace="/" includeParams="all" id="histURL">
 <s:param name="sources" value="sources"></s:param>
</s:url>
${histURL}

results in

http://localhost:8080/myproject/theaction&sources=com.mycompany.Source@32324&sources= ...

So the collection as a paramater works, I just assumed that the OGNL projection works well but seems to be buggy. Or am I missing something? Is this OGNL at all? 🙂

Thank you for your replies!

Answer 1

I’m dumb.
This is just the way, I missed that I used a wrong class, which had no Id at all.
It’s definitely OGNL and it works like charm 🙂
