ActionErrors & logic:iterate

["ZACHCIAL,SLAWOMIR (HP-France,ex1)" <sl...@hp.com>]

Hi,

Currently ActionErrors class has method "get" returning the iterator of all
the errors. Unfortunately, as far as I know you can't use this feature
directly with <logic:iterate> tag as it the method name is not
JavaBeans-like (getXXX).

The only way I found today to use ActionErrors with <logic:iterate> is:


<bean:define id="errors" 
             name="<%=org.apache.struts.action.Action.ERROR_KEY%>"
             type="org.apache.struts.action.ActionErrors"/>
<strong>The following error(s) occured:</strong>
<ul>
   <logic:iterate collection="<%=errors.get()%>" 
                  id="error" 		
                  type="org.apache.struts.action.ActionError">
   <li><bean:message key="<%=error.getKey()%>"/></li>
   </logic:iterate>
</ul>


Why not to change the method name from "get" to something like "getErrors"?
The the code above
would look like:


<strong>The following error(s) occured:</strong>
<ul>
   <logic:iterate name="<%=org.apache.struts.action.Action.ERROR_KEY%>"
                  property="errors" 
                  id="error" 		
                  type="org.apache.struts.action.ActionError">
   <li><bean:message key="<%=error.getKey()%>"/></li>
   </logic:iterate>
</ul>


Or maybe did I missed something?

Yes, that method should probably be renamed to something like getIterator() or
something.

Just out of curiosity, what would happen if you set the property to "", would
the Introspector still just pre-pend "get" to a blank string and call the
"get()" method on the ActionErrors class?
