hi some times I got error when I am not passing IRequestCycle as parameter to listener method.
To initialize the parameters there is initialize method you also can have a look at detach method and see.page begin render is , if you want to do something before any component renders itself. Page validate is if you want to do any validations like user is authenticated or not and any other page validations you can use it.

I must admit, this was a bit trial and error. I pass the personId parameter via the following code in another component. @InjectPage("Details") public abstract Details getDetailsPage(); public IPage doShowDetails(int personId) { Details details = getDetailsPage(); details.setPersonId(personId); return details; } } Where this code gets set up in the html template for this component as <div class="surname"> <span jwcid="@DirectLink" listener="listener:doShowDetails" parameters="ognl:person.id" ><span jwcid="@Insert" value="ognl:person.surname" >Chandler</span></span> </div> I think PageBeginRender failed (thinking back to when I orginally had it here) because there seems to be a validation phase of the page before then, and I had not set up the record, and had null pointer exceptions. I think the page initialisation failed because the setPersonId call hadn't happened (maybe - difficult to remember now) the initialisation got called when I did the first call to getDetailsPage in the listener above. -- Alan Chandler http://www.chandlerfamily.org.uk --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
