Hi.
I think I've found problem/error in Eclipse databinding framework,
at least in javabean example.
This is what I've posted on eclipse.tools.ve newsgroup:
---
I've copied the org.eclipse.jface.examples.databinding.javabean classes
into my project, in order to be able to play with them safely.
But they wouldn't work. I tried to debug, and found problem in
getGetMethod() method of JavaBeanUpdatable() class (look at the try
statement - it has local variable Method getMethod so it will never
return value.
I fixed this, and it runs but... still doesn't work. I mean: I have window
with labels and text boxes, but changing value in one box doesn't
change value in other box. Why?
---
I've tried to debug a little, and it seems that in mentioned example
there are weird events in typical scenario, e.g. one changes first
name in one of text boxes. This is what happens:
1. I add "xx" to first name, so it is now "Johnxx".
2. I press tab, so change is noticed by data binding objects.
3. These objects update the "person" object, so its firstName
property has also value "Johnxx".
4. Then something weird happens - instead of updating second text
box to reflect new model state, the data binding objects update
model to reflect second textbox state.
5. So now we have: first text box with text "Johnxx", model with
property value "John" and second text box with text "John".
Does anyone know why the framework doesn't work?
Best regards,
