No Design Tab

[electronicpowert]

I just install GWT Designer the second time. I can create a new project as in the LoginManager example. Everything seams correct but in the java editor I don't see the Design and the source Tab.

What is wrong whith my installation?

Thomas

You need to change which editor is used to open those files. Right click, Open With, WindowBuilder Editor.

[electronicpowert]

Thanks for the quick answer!

I installed eclipse and GWT designer the third time. And now after creating the project the correct editor shows up. Both Tabs are visible.
Last time I added the android developing tools in eclipse. Can that be the reason that the editor was changed?

[Eric Clayberg]

Very unlikely. Multiple editors are available in Eclipse to edit Java files. Just make sure that you are using teh correct one...

Hy there,

I'm currently evaluating the SWT Builder and I do face the same problem. I have several projects in my workspace, and in all but
one I can successfully use the WindowBuilder Editor. So in one of the projects, even when manually selecting open with->WindowBuilder Editor and opening
a class extending Composite I do not see the Window Builder Editor (although the Icon on the tab says that it is the WindowBuilder editor).
But no source, design and databinding tab!

Info: OS X 10.6, Eclipse RPC 3.6 just updated your packages.

please help!

cheers,
marco

PS: maybe this is a hint:

[Eric Clayberg]

Please provide screen shots of what you are seeing and an example class where you see this happen. We also need to see your complete Eclipse ".log" file.

[marcode]

please see above, i could not find any specific messages in the logfiles.

[Eric Clayberg]

We need to see your complete Eclipse ".log" file showing the above exception and any preceding exceptions.

[marcode]

This is the logfile on the following sequence of steps:

1. Open Eclipse
2. Open File -> http://elexis.hg.sourceforge.net/hgweb/elexis/elexis-base/file/6908e7183395/elexis/src/ch/elexis/views/Patientenblatt2.java
3. Close Eclipse

The result is as shown above in the screenshot!

[Eric Clayberg]

Does this happen with all classes you edit or only this specific one?

We still need to see your complete Eclipse ".log" file showing the NPE you reported earlier. Your latest post does not show that at all.

[marcode]

This happens to all classes within the project, as soon as I switch the project I can access the DesignBuilder editor correctly.

The Exception formerly presented does only happen when manually opening the WindowBuilder/Structure view with the class opened.

This is the full error log, I cant find any more logs except for the default plugin configuration info:

[Eric Clayberg]

We have not been able to reproduce this using any combination of steps under any OS.

This happens to all classes within the project, as soon as I switch the project I can access the DesignBuilder editor correctly.

Are you saying that it only happens with one project? If you close and re-open the project, does it make any difference?

Can you send us the project?

The Exception formerly presented does only happen when manually opening the WindowBuilder/Structure view with the class opened.

Is the class opened in the WB editor at the time?

[marcode]

Yes, it only happens within this specific project. Closing and reopening the project does not make a difference.

If I first open the resp. File (Patientenblatt2.java) the design tab is not shown, if I then (with the File openend) select
Show View/Window Builder/Structure the aforementioned Exception is thrown!

It is really as this: Only in this specific project I do not see the tabs (source/design/databinding) but in every other project SWTBuilder works flawless!

The project is http://elexis.hg.sourceforge.net/hgweb/ ... 395/elexis. There are a lot of subprojects in this tree,
but the error only happens within the elexis project (which forms the main rcp-product, whereas the other are bundles).

[Eric Clayberg]

I'm sorry, but we have not been able to reproduce this with the project you referenced. We tried it on several different machines using both Windows and OSX. See below...

The only thing I can think of is that possibly your Eclipse meta data is corrupt for this project.

What happens if you delete it and re-load it? Can you try the same project on other machines?
