Again error with handling actions

Postby CrystalPalace » Sun Sep 05, 2004 4:47 am

Hello Eric,

I just downloaded 2004.09.03 release and now whenever I create a new ApplicationWindow and try to add an action, two error dialogs occur with the following log messages:
Code: Select all

A fresh installation of both eclipse 3.1m1 and 3.0 does not solve the problem! :cry:

changing the java VM to 1.5 rc also does not solve the problem

:D Yeah now it works again, but with a minor flaw :-)

When you double click on the action item, I would expect to jump to the run() procedure of the action class.
Instead, Designer takes me only to the ApplicationWindows´ createActions() where the action class is created.
I am just wondering if that was the intention how double clicking on the designer action definition should work

Thx,

Christian

Double-clicking will take you to the createActions() method and place the cursor at the location where the Action is instantiated. For an anonymous Action class that Designer created, there is a further refinement in that it will take you to run() method within the Action class definition.

Currently, the Action editor double-click routine knows where each Action is created, but not where its class is defined (it just happens that for an anonymous class, those two locations are the same). For the general case of an Action created by the user, the Action class could be an inner class created in the same compilation unit or it might even be in a different compilation unit entirely.

We certainly could enhance the double-click routine to do as you suggest, but it would entail quite a bit of additional coding. The original intent was not to have it do as you suggest in the general case, but we could certainly enhance it at some point to do that.
