Eclipse plugin 15.1 - Widget is disposed

Hello,
editing an XSD schema I got the following error (and it keeps repeating once in a while now, probably won't stop until I restart eclipse).
Don't know the exact steps to reproduce it, I was using the visual editor, Attributes and Facets views and Edit attributes context menu.

Code: Select all

Hi,

How did you install the Oxygen Eclipse plugin (update site or zip distribution)?

Can you please check if you are indeed running v15.1 (Help > About Eclipse, click on the Oxygen icon)?
I've checked the stack trace you reported, but it doesn't match the code in v15.1, but v15.0 instead.

Regards,
Adrian

Hi,
must have pasted the wrong log entry then, sorry.
Here is the correct one I suppose:

I noticed it happening when setting the type of an element using the context menu Edit attributes, then closing the popup window and activating the Attributes view.
Hope this helps.

Hi,

Thank you.

We could not reproduce the problem by following the instructions you have provided. Is the problem consistent?

Can you please provide more specific details about what you changed in the 'Edit attributes' panel?
A sample (or at least a snippet) of the XML Schema from the modified region could also be useful for us in reproducing the problem.

If you want to keep this private, you can write to our support email address: support AT oxygenxml DOT com.

Regards,
Adrian

Hi,
here's how I managed to reproduce it:

1. start Eclipse (4.3.1)
2. show Attributes view
3. create sample XML project
4. open up personal.xsd in Design editor
5. on /person/@note click Edit Attributes context menu item
6. change type to xs:integer
7. close Edit Attributes popup by system close button (this is important, if you use the gray X inside the window, the error does not appear)
8. click on Attributes view tab, the error appears

Regards

There shouldn't be a system close button for that panel (in Ubuntu there isn't one), only the gray X inside the window.
What distribution of Linux and what window manager are you using?

Adrian

Hi,
I'm using Xubuntu 12.04 LTS, with XFCE 4.8.

Hi,

I've installed the Xubuntu desktop packages under Ubuntu and was able to reproduce the problem.
For some reason XFCE adds a title bar and system maximize/close widgets even though the Edit Attributes dialog should be undecorated (Unity). The system close is not handled correctly by the Oxygen plugin (was not anticipated) which leads to the Widget is disposed error.

I've logged this to our issue tracking tool to be resolved in the next release of Oxygen. We will notify this thread when the bugfix becomes available.
Meanwhile, please do not use the system close button from the Edit Attributes dialog, instead use the X button inside the window (or press ESC).

Regards,
Adrian
