Hi,
maybe the problem is only due to the undergoing work on the Photon Eclipse Train, but just in case I would like to make it known.
I am testing WB (1.9.0, from IDE Marketplace) on latest Photon build

Quote:
Eclipse IDE for RCP and RAP Developers
Version: Photon Release Candidate 1 (4.8.0RC1)
Build id: 20180524-1423
OS: Linux, v.4.15.0-22-generic, x86_64 / gtk 3.22.30, WebKit 2.20.2
Java version: 1.8.0_171

Linux=Ubuntu LTS 18.04 / GNOME
Windows=Windows 7


but when I try to open a view I see an empty area while the Error Log shows:

Is there some others having the same issue?
Thank you very much

I'm not answering your question, but rather using it to make a non-related point.
File "UndoManager.java" is _not_ in the Git repository that [supposedly] contains the WindowBuilder source code. Why is that?

Hi Avi,
I cloned WB source code from its Git repository (see also https://www.eclipse.org/forums/index.php/t/1093240/)
which is the following

git://git.eclipse.org/gitroot/windowbuilder/org.eclipse.windowbuilder.git

and I can assure that file "UndoManager.java" is there (see image)


index.php/fa/33042/0/

You'll see it also here:
https://git.eclipse.org/c/windowbuilder/org.eclipse.windowbuilder.git/tree/org.eclipse.wb.core.java/src/org/eclipse/wb/internal/core/editor

Are you cloning from the same Git repository?

Thank you Vincenzo.
Your screen shot led me to discovering how to correctly download the WindowBuilder source code.

Thanks!

Hi all,
I tested latest Photon release

Quote:
Eclipse IDE for RCP and RAP Developers
Version: Photon Release Candidate 3 (4.8.0RC3)
Build id: 20180607-0625
OS: Linux, v.4.15.0-23-generic, x86_64 / gtk 3.22.30
Java version: 1.8.0_171

with latest WB release 1.9.1.201806150629
taken from
http://download.eclipse.org/windowbuilder/WB/integration/4.8

but the problem on Linux (I am using Ubuntu 18.04) is still there (the IDE crashes as soon as I try to open the WB Design view).

Bug was also posted here
https://bugs.eclipse.org/bugs/show_bug.cgi?id=535642

@WB Project Team: is there something I can do on my environment to make WB work on Linux?
@WB Users on Linux: are you having the same problem? If otherwise it works for you, can you provide details on your Linux environment (distro, version, desktop environment, ..)?

Thank you very much
Vincenzo
