Hello,
I have ported an PBProj/Xcode application over to Eclipse. This
application has been coded to use Direct Actions; however when I
run this application it fails because it cannot resolve a default
'action class'.
No, you're wrong. You are mis-reading the error message. See below.
Following are the details.
Application.java sets direct actions as default:
WORequestHandler directActionRequestHandler =
requestHandlerForKey("wa");
setDefaultRequestHandler(directActionRequestHandler);
DirectAction.java specifies the default action:
public WOActionResults defaultAction() {
return pageWithName("Main");
When I run the app, an ErrorPage is displayed(NOT Main page), and
the Console displays the following error:
<com.webobjects.appserver._private.WODirectActionRequestHandler>:
Exception while handling action named "default" on action class "null"
That means it found and ran the requested action.
:com.webobjects.foundation.NSForwardException
[com.webobjects.appserver._private.WODynamicElementCreationException]
null
The real problem is a WODynamicElementCreationException
[2007-03-06 10:11:03 EST] <WorkerThread0>
com.webobjects.foundation.NSForwardException for
com.webobjects.appserver._private.WODynamicElementCreationException:
<com.webobjects.appserver._private.WOImageButton> 'Either a
component action or a direct action must be specified.'
Somewhere in Main.wod you have a WOImageButton. It has neither the
action or directAction binding set on it.
This error completely puzzles me because my understanding is that
the 'defaultAction' method of 'DirectAction' class is called by the
WebObjects framework when you first connect to the application. And
this class is definitely present in the application, so I cannot
understand why it is reporting an "action class "null", or in other
words, is not recognizing the (bootstrap)DirectAction class.
It is important to actually read the _entire_ error message and not
jump to conclusions based on a few words in the first line. If read
(and thought about), the error messages are usually quite informative.
