Does not work with Java applications and has issues with vnc

[Andrew]

When I have diodon loaded, I cannot copy text, either via the primary selection, or the clipboard in java (Oracle JDev IDE). If I shut down diodon, it starts working again.

I have also seen similar issues when trying to use clipboard transfers with remmina (vnc client).

I really like diodon and its integration with unity, but this bug really makes it difficult to work.

I've tried to reproduce this issue however haven't been successful so far ;).

I have to sign up to get JDev therefore I did some testing with jedit and soapui. When diodon is closed the primary selection is not working either in those Java Applications. So this seems to be a general issue with Java Applications.

However Ctrl+C works as expected. But it does work without any problem on my system as well when Diodon is started.

So before I download myself JDev could you quickly test whether JEdit works together with Diodon on your system? It might be a JDev specific error.

Okay, in jEdit, with diodon open:
I cannot highlight in jEdit and paste into gnome-terminal (middle-mouse)
I cannot ctrl+c in in jEdit and paste into gnome-terminal
I cannot ctrl+insert in in jEdit and paste into gnome-terminal

After closing diodon:
I can highlight in jEdit and paste into gnome-terminal (middle-mouse)
I cannot ctrl+c in in jEdit and paste into gnome-terminal
I cannot ctrl+insert in in jEdit and paste into gnome-terminal

Note that I use a Dvorak keyboard layout and usually use ctrl+insert to copy instead of ctrl+c

Okay, running:
/usr/lib/jvm/java-6-openjdk/demo/jfc/FileChooserDemo$ java -jar FileChooserDemo.jar

In there, if I open the file chooser and select a file, then using the "File Name:" input text to copy and highlight text,

I still cannot paste ctrl+c/insert into gnome terminal, but I found that everything works when pasting into gvim.

Not sure if gnome has a different clipboard storage than what gvim uses? Very odd, but I am not too shocked knowing linux's complexity of clipboard apis.

I cannot paste from jedit into Gnome Terminal either no matter whether Diodon is running or not. On the other hand, jedit to gedit always works.

When selecting a text in jedit and using middle mouse click to paste it into the gnome terminal works well even when Diodon is running.
However it seems that when selecting or copying a text from jedit such item does not appear in the Diodon history.

Therefore marking this bug as confirmed.

Strange. On my office computer running Lucid I can reproduce the issue.

It seems some applications store text in the clipboard but the clipboard tells me that there isn't any. However when checking there is.... ;).

Added a workaround for this. Should be available for testing in the daily ppa soon.
