[S2] getting property value / OGNL calling a method of my model object with an argument

Hi,

more confusion. I'm trying to call a method in a model object with a  
Long (type doesn't really matter though) argument:

         <s:iterator value="categories">
             <s:property value="description.title"/><br />
             Activity id: <s:property value="activityId"/><br />
             String: <s:property value="boomerang(activityId)"/><br />
             No arg: <s:property value="boomerang"/><br /><br />
         </s:iterator>

According to the OGNL docs, adding an argument needs parenthesis, as  
I'm doing in 'boomering(activityId'.

This isn't working :( 'boomerang' without argument does work, it's  
returning a string like it should. getBoomerang(Long l) nor  
getBoomerang(String s) works. They're never called by Struts/ognl.

What am I missing? Is this supposed to work or not?

Thanks.

bas.

Ok, that does indeed work!

Thanks.

Passing in an argument means it's no longer a simple getter, so you have 
to actually call the method. Only real JavaBean getters work without the 
"get" prefix.

<s:property value="%{getBoomerang(activityId)}" />
