In all the webwork tags the value parameter is the expression language value the tag shall act on. For url tag <ww:url value="'foo'"/> is the same as <ww:url page="foo"/>. The value parameter is there to enable you to take the page attribute from an object on the value stack. It would seem this isn't documented at all unfortunately. > 2.

When is the id attribute used to push things onto the value stack? <ww:property value="foo" id="bar"/> will grab the object foo from the value stack and put it into the page context. ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Opensymphony-webwork mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/opensymphony-webwork
