Can I use a Parameter in result definition?
Hello all...
Does anyone know if it is possible to use a parameter in my
action/result definition:
I want to use the package name in the result definition
<package name="component" extends="base-package" namespace="/component">
<action...
<result name="success"
type="tiles">view-{0).panel</result> <!-- SUBSTITUTE component for {0}
-->
</action>
</package>
Would become:
<package name="component" extends="base-package" namespace="/component">
<action...
<result name="success"
type="tiles">view-component.panel</result>
</action>
</package>
Is this possible?
Thanks in advance,
MG

I added a bit to the upgrade instructions. Changing the javadoc
requires svn commit privileges, though...

That wouldn't be hard.

I just looked in the source and see that it should now work with either.
I changed my current app and it worked!
Should we change the documentation? (Is it documented anywhere other
than the javadocs?) Should we include that change in the upgrade
instructions?
Now that you've looked at this in more detail, assuming anyone ever gets
alternative scripting languages working, does the possibility of making
them all work and be selectable based on the character %{} for ognl, ${}
for jstl, #{} for mvel, etc. seem possible?

How to initialize a List property through action configuration
Posted by Struts Two <st...@yahoo.ca>.
If I have a property such as
private List<String> myList;
....
....
Is there a way that I can initialize the list through action configuration? I have tried the following:
#action name="queueContent" class="ccol.action.queue.QueueRead" method="getMyQueueContent"#
#param name="myList"# {Alarmed,Open} #/param#
#result name="success"# myQueueContent #/result#
#/action#
and
#action name="queueContent" class="ccol.action.queue.QueueRead" method="getMyQueueContent"#
#param name="myList"# Alarmed #/param#
#param name="myList"# Open #/param#
#result name="success"#myQueueContent#/result#
#/action#
For the last case, the list is initialized with Open [which makes sense as Alarmed gets overwritten, but I just wanted to try].

Re: How to use "s:include" param in s:if
Posted by Struts Two <st...@yahoo.ca>.
I was trying to avoid <% if(....) ...%> in my jsps by using request Object and since I am not using JSTL in favor of struts 2 tags, <c:if ...>
tag is not possible.
I have managed to get around the problem with a less favorable approach. My <s:include> now looks like:
<s:include value="./includes/tabs.jsp">
<s:param name="tab1Class" value="%{'on'}" />
<s:param name="tab2Class" value="%{'off'}" />
</s:include>
and in my tabs.jsp I have someting:
<td class="${param.tab1Class}" >...</td>
<td class="${param.tab2Class}" >...</td>
What I do not like about this approach is If I add a new tab, I not only have to update tabs.jsp but every single jsp that includes it.
I believe <s:include> tag should be able to handle a simple case like the one I was trying to do.
Anyways, thank you for your replies and time.

Hmm... Strange. I don't know if it matters, but ${param.tab1} probably works
because it's a legit EL expression. Your include points directly to a JSP,
rather than an action. Try doing the whole thing in EL, you might be able to
accomplish what you're looking for with less hassle.

Wes ,
Thank you for your reply, Unfortunately that does not work. The if statement return false [I print ${param.tab1} on the page and it has the value 'tab1' yet if statement is false]. I am using struts 2.0.14.

How to use "s:include" param in s:if
Posted by Struts Two <st...@yahoo.ca>.
I have run out of options and I was hoping if someone can help me. I have an include tag as follows:
<s:include value="./includes/tabs.jsp">
<s:param name="tabId" value="%{'tab1'}" />
</s:include>
In my tabs.jsp, I tried to do the following:
<td <s:if test="%{#request.param.tabId == 'tab1'}">class="on" </s:if><s:else>class="off"</s:else> >
But of no avail. Using ${param.tabId}, I can see the value of tablId. I even tried [crazy ideas like]:
<td <s:if test="%{${param.tabId} == 'tab1'}">class="on" </s:if><s:else>class="off"</s:else> >
<td <s:if test="{${param.tabId} == 'tab1'}">class="on" </s:if><s:else>class="off"</s:else> >
Refering to "Struts 2 in action" and "Struts 2 Design and programming" was of no help.
I would appreciate if anybody helps me on that.

It looked like the only place you wanted to use this substitution was in
a result tag. I didn't notice what value it was you wanted until now.
The action is on top of the value stack when that's evaluated, and there
should be some way to get to that info from there...so if you make your
BaseAction class include a getNamespace() method that does the right
thing, you can say %{namespace} in the struts.xml like you asked.
I've got to sign off, so I'm not providing the magic incantation to get
this from the action, but I bet there's some way to get it. I don't see
it right now, but I thought there used to be an ActionMappingAware
interface, for example...

Cool, but looking at the doc, it looks like the only place I can declare
a parm is in the result tag?
Something like this:
<result name="success" type="tiles">view-{packageName}.panel</result>
How do I declare the variable at the package level so I don't have to
redeclare each action and result?
