Passing jsp tag attribute to Struts 2 tags
Hi,
I am creating a new tag in jsp, named `RequiredLabel` , but I can not pass tag attribute to struts label ( The css are based on YAML)
The tag will be used as:
<myTag:RequiredLabel name="amount"/>
The label should be get from struts as it must be localized.
<%@tag description="Renders a label with required css and error label" pageEncoding="UTF-8"%>
<%@attribute name="name" required="true" %>
<%@taglib prefix="s" uri="/struts-tags"%>
<!--Here ${name} works fine -->
<p class="ym-message" id="${name}Error" />
<!-- Here I can not pass the name to s:label tag -->
<s:label key="form.label.%{name}" cssClass="ym-required" />
I tried `#attr.name` and `#param.name` but none of them worked!
Do you know any solution ?!
~Regards,
~~Alireza Fattahi

Untested, and I didn't check the docs... but your expression in attribute
"key" of the following would require double evaluation. This is because an
attribute is a simple String or an OGNL expression. Your value in key
requires that concatenation occur after evaluation...
<s:label key="form.label.%{name}" cssClass="ym-required" />
In stead an expression of the form: "%{"form.label." + name}", would be
better. Although there is still the issue of _name_ being in scope, maybe
you will need an " #attr." prefix...

Actually I am not calling any action class getKeyLable
I try to:
1- Make the s:label tag get a dynamic (Is it poosibel ?!)
2- The above dynamic value must be read from jsp tag ( The s:label is used in a tag itself)
