OGNL question
Hi,
How could i do that
<s:url id="setUsina${id}" action="UpdateHome!selectPlant">
</s:url>
<s:a id="any"
name="any"
href="%{setUsina${id}}" theme="ajax">Link</s:a>
changing EL by OGNL?
The especific part href="%{setUsina${id}}" . I tried
href="%{setUsina(#id)}" but didn't work.
Thanks,
Felipe

Again, why do you need to make the id attribute on the s:url tag
dynamic? Just use <s:url id="url" ... as I suggested in a previous post.

You have href="%{url}" but used id="url%{id}" in the s:url tag above.
Fix the s:url tag, and this should work fine. The id attribute on the
s:a tag *does* need to be unique, since it becomes part of the rendered
HTML. The id attribute on the s:url tag doesn't, but the s:a's href
attribute must sync up with the s:url's id attribute.

You should be able to get this working using either s:iterator or
c:forEach. Try the suggestion above and, if you still have problems,
post the errors you get and/or the incorrect markup that's produced.

Re: OGNL question
Posted by Felipe Rodrigues <fe...@yahoo.com.br>.
I got it using <c:forEach> again. I didn't realize that I can use EL to get
values from some Action as well.
But I keep wondering if I can't do that by using <s:iterator> and OGNL.
Thanks,
Felipe

Re: OGNL question
Posted by Felipe Rodrigues <fe...@yahoo.com.br>.
I'm sorry about don't provide all the informations. I'll try to explain a
little more.
I'm trying to generate a <s:a> tag for each item in a list, but I have to
send a param when click on this <s:a> link.
This is why I use <s:url> to do that. My code seems like that:
<s:iterator value="type">
<tr>
<td>
<s:url id="url%{id}" action="Variables">
<s:param name="typeId" value="id"></s:param>
</s:url>
<s:a id="tipo${module}%{id}"
name="tipo${module}%{id}"
href="%{url}" <!-- Here is my problem. I need lots of url, but not
with the same id, because my param changes
according to the type I'm itereting
-->
cssClass="listItem"
notifyTopics="changeTypeListItem"
theme="ajax"
showLoadingText="false"><s:property value="dsc"/></s:a>
</td>
</tr>
</s:iterator>
I was doing this with <c:forEach>, but some changes in my project made me
change from <c:forEach> to <s:iterator>. When using forEach I could just use
EL, but with iterator, I can't (I think I can't, but not sure).
How could I do that in this case?
Thanks in advance,
Felipe

Re: OGNL question
Posted by Laurie Harper <la...@holoweb.net>.
Why do you need to make the url-id unique on each loop iteration? Have
you tried simply writing something like
<c:forEach ...>
<s:url id="url" .../>
<s:a href="%{#id}" .../>
...
You should, on the other hand, provide a unique value for the 'id' (and
possibly 'name) attribute on the s:a tag as those get passed through to
the rendered HTML.
If you're still having trouble, try describing what exactly you are
trying to achieve, and posting a more complete code sample of how you're
trying to achieve it.

I'm sorry, but I didn't got it.
When I pass in a parameter, I'll send it to the destiny. That is not what I
want. I only want to identify the url according to the id. This code is
inside a foreach, that renders lots of urls.
How would be that in this case?
Thanks,
Felipe
