Is this a BUG in S2
Hi,
We are experiencing that action attribute of the
<s:url tag is not evaluating the expressions.
For e.g Inside a interator if we want to get dynamic
action names from the interator and assign into the
action tag of the <s:url tag it just prints the text
as it is without evaluating.
Even tried <c:out of the jstl inside the action
property as follows in side a iterator but didnt work.
<s:iterator id="testID" value="xxxxxxxx">
<s:set name="testActionName" value="actionName"/>
<tr>
<td valign="middle" bgcolor="white" >
<s:url id="url" action="<c:out
value='${testActionName}'/>">
.....
.....
Is there any way to overcome this kind of
requirements.
Thanks

You mean the editor complains?
Could just be a setting for whether or not you want it to allow you to
use scriptlets. Or you might be using the non-rt version of the TLDs and
the BEA IDE is smart enough to care? Not sure about that one.
(Drat, my Weblogic IDE won't start up now, either :/ I always just used
Eclipse/MyEclipse.)

Posted by "Baskin, Wayne (GE Comm Fin, non-ge)" <wa...@ge.com>.
Hi all,
I want to know is there any reason why with one IDE (Bea WebLogic) I
cannot nest scriptlet tags in a struts tag, but with another Eclipse, I
can?
Thanks

Re: Is this a BUG in S2

Hi,
if the action string is being evaluated in the URL tag
what does it output the expression as it is, If we
have the same expression in value attribute it does
evaluate, That is where we are doubtful.
In portal mode the action attribute does convert the
string to portal string where as value does not.
Hence we need to get the expression evaluated in the
action attribute
Thanks

In the simple case, this:
<s:url id="url" action="${courseName}">
and this:
<s:url id="url" value="${courseName}.action">
would be identical. You can also use the <param> tag to include request
parameters. You can create any URL you need using the value attribute
and params.
You referenced portal in your email so you might be using this in a mode
I haven't tried. Looking at the code for s:url, the action string IS
being evaluated but there's extra processing (a lot) to convert into a
URL. The behaviour depends on whether you're in portlet mode or not. If
you put a break-point in the end(writer, body) method of
org.apache.struts2.components.URL.java you'll see where it's going wrong
for your case. I don't think this is a bug in S2.

Re: Is this a BUG in S2

Yes you are right,
Even though action attribute doesnt get evaluated
value attribute does,
but that is of no use as it does not create the URL
string to suite with Portal env.
The biggest concern is why the action attrbute of URL
tag doesnt evaluate.
that is following doesnt work
<s:url id="url" action="%{courseName}">
</s:url>
but this does but no point as it doesnt render the url
as per portal requirement
<s:url id="url3" value="%{courseName}">
</s:url>
That is why I would like to call this as a bug-not
evaluating the action attribute of url tag

The "value" attribute creates the href if the "action"
attribute isn't used.

Re: Is this a BUG in S2

Hi,
Thanks for the reply,
I tried both but with no luck,
Option 1 as stated I gave $actionName but doesnt
evaluate and for the second one there is no href
attribute for the URL tag hence doesnt work.
I tried various combinations like
c:out, ${actionName}, ${testID.actionName} and also
%{actionName} and %{testID.actionName}
none worked, the reason is, it does not evaluate the
tag eventhough the specification says yes.
These are the reasons I want to confirm this as a bug
or not, but let us know your thoughts as well.
Thanks

I haven't tried to use a dynamic action name like that so can't comment
on whether its a bug or feature, but one of these options should work:
1. Try using the ${} notation without the c:out
<s:url id="url" action="${actionName}">
(I can't find the reference for this approach but it's somewhere on the
wiki)
2. Alternatively, work-around it by using the href attribute:
<s:url id="url" href="${actionName}.action">
href definitely does work.
