Looks like a bug to me. I'm not familiar with that code, but it looks like the "isAssignableFrom" is trying to only use an existing attribute as the ActionForm if it's of the correct type (or subtype) of the specified ActionForm type. The result of the second "return" is that it will use that attribute even if it's not of that type. If the second "return" was removed, it would instead try to create a new instance of the specified ActionForm type.
It looks like this change went in (by Craig) quite a while ago (version 1.36, 6/22/2002). I have a feeling it was an accident. -----Original Message----- From: Sri Sankaran [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 28, 2003 1:57 PM To: Struts-User Subject: [Struts-src] Creating a form-bean I was wading through the source code to figure out the process of creation of a form bean and found the following snippet in o.a.s.u.RequestUtils in the method createActionForm (line 654 in the 1/28 nightly source): (beginning at line 709) if (configClass.isAssignableFrom(instance.getClass())) { if (log.isDebugEnabled()) { // snip } return (instance); } return (instance); Can you tell me what this the if-statement is accomplishing? It looks like 'instance' will be returned regardless. Sri -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
