Chris, Use <tiles:importAttribute .... ignore="true"> to bring in the key. You can then use EL to test if it is empty or whatever.

If this isn't possible, could someone let me know? Then I could try to find an alternate path. Chris -----Original Message----- From: Chris Loschen Sent: Wednesday, June 08, 2005 5:09 PM To: Struts Users Mailing List Subject: RE: Test whether an application resource is empty I'm still spinning my wheels on this -- does anyone have any ideas? Quick synopsis: I have localized i18n messages defined in my tiles definitions which are sometimes empty. I need to test that the value associated with a given key is not empty before I proceed with further processing. I can test that the key is non-empty, but I haven't yet figured out how to test the same thing for the value. If anyone could help, I'd really appreciate it. Thanks! Chris -----Original Message----- From: Chris Loschen Sent: Wednesday, June 08, 2005 1:12 PM To: Struts Users Mailing List Subject: Test whether an application resource is empty Hi all, I'm using struts 1.1. I have localized application resources keys defined in my tiles definition file. In my JSP, I use the tiles attribute and then display the localized message using the key. However, in some cases, the localized value is empty: there is no value for that particular locale or that particular instance. In those cases, I want to avoid writing out the key at all, but I'm having trouble figuring out how to make that test. Specifically, I have tiles defs like this: <definition name=".manageHierarchy.billing.details" extends=".template.manageHierarchy.billing"> <put name="directionToUser" value="tiles.module.admin.manageHierarchy.billing.details.directionToUse r"/> Etc. </definition> And the localized values are something like tiles.main.admin.manageHierarchy.businessStruc.add.directionToUser= (so no value for that key). In my JSP, I've tried several ways to test whether the key value is null or the length is 0, but none of them have worked yet. For example: <tiles:useAttribute id="directionToUser" name="directionToUser" classname="java.lang.String" ignore="true"/> <% if(directionToUser != null && directionToUser.length()>0){ %> <div class="modFormBox"><bean:message key="<%=directionToUser.toString()%>"/></div> <% }%> Problem here is that directionToUser is the key, not the value, so it's never null, and I get the empty div tags I'm trying to avoid. So I tried variations like this: <tiles:useAttribute name="directionToUser" classname="java.lang.String"/> <bean:define id="directionToUserString"> <bean:message name="directionToUser"/> </bean:define> <logic:notEmpty name="directionToUserString"> <div class="modFormBox"><bean:write name="directionToUserString"/></div> </logic:notEmpty> That one returned "Define tag can contain only one of name attribute, value attribute, or body content". I've tried lots of variations similar to that, but haven't struck upon the right one yet. This SEEMS like something which should be pretty simple, but I'm missing something. Any suggestions? Thanks!
