Exception on copy smth from the system

[Chris2011]

I have a strange bug. I open chrome, select the address bar and hit ctrl + c (sometimes more than one times, to ensure, that I copied the text. Unfortunately netbeans give me this exception:

very strange, only happens inside the addressbar.

Added ignoring for IllegalStateException with clipboard.

Should be ok. Thx. :)

It happens again, but I figured out when, only when I using the Windows Edge browser.

I tried to add more ignores.

[Chris2011]

I will test it thx, but why is the plugin listen to the copy/paste logic?

[hajdam]

Primary reason lies in deltahex editor, where it listens on changes of clipboard flavor to highlight if paste operation is available in toolbar. In netbeans plugin it's currently used only for context popup menu, but that might be called on menu creation, so maybe I could remove that...

[hajdam]

please increase your version number next time. I wanted to downloaded and installed it but it wasn't possible because I already have a version 0.1.4.

Versions of plugins in NetBeans seems to be a bit limited, therefore I cannot distinguish between release and development versions properly. Therefore I increase version only once after each release.

As you tried development version, to install release version with the same version number, you need to uninstall plugin first via Tools/Plugins - tab Installed - check Show details - search for deltahex - select plugin and hit uninstall. (Or faster way is to delete nbm file directly)

[Chris2011]

Ok I understand that. thx.

[Chris2011]

It seems fixed. thx for the work.

[hajdam]

I'll delete your comment on netbeans plugin page, as it's incorrect, I guess...
