Re: tiles and parameters

[Frank Maritato]

That didn't work. First I got a ClassCastException because its actually 
of type org.apache.struts.tiles.DirectStringAttribute and not 
java.lang.string. Even after I adjusted for that, however, I still was 
not able to see nav_key or local_nav_key in samplecontent.jsp.

That tiles reference was very helpful though. It said that all 
attributes are defined in the "tiles" scope only and are not visible to 
sub-tiles. That gave me the idea to redefine the variable into the 
request scope. So this is what I did:

in headerContentFooter.jsp:
<bean:define id="nav_key" name="nav_key" toScope="request" />
then in samplecontent.jsp:
<bean:define name="nav_key" scope="request" ignore="true"/>
and that works. Thanks!

Frank,

Try this in headerContentFooter.jsp

<tiles:useAttribute id="local_nav_key" name="nav_key" 
classname="java.lang.String" ignore="true" />
<p>nav_key = <%=local_nav_key%></p>

Here is a good reference for tiles

Hi all, I'm having a problem passing a parameter down from a tiles 
definition to a jsp. I can access the value easily in the layout 
definition, but I can't get access to it in a file (or action) I'm 
inserting into the layout. Here is an example of what I'm doing (cut 
down a bit)

tiles.xml:
<definition name="mp.main" path="/tiles/layout/headerContentFooter.jsp">
  <put name="nav_key"    value="mp" type="string"/>
  <put name="content"    value="/showcontent.do" />
</definition>
headerContentFooter.jsp:
<tiles:useAttribute name="nav_key" />
<p>nav_key = <%=nav_key%><p>
<tiles:insert attribute="content" />
samplecontent.jsp:
<bean:define id="nav_key" name="nav_key" />
<b>nav_key::: <%=nav_key%></b>
So I'm getting an error in samplecontent.jsp that there is no such 
variable in any scope. How can I get it? I can print out the value 
fine in the headerContentFooter layout. I also tried adding a 
<tiles:useAttribute> in samplecontent.jsp to try and get access to the 
variable but that didn't work either. Any help would be appreciated.

Thanks!
