explorer body is becoming blank with out errors

[penusila611621]

Hello All,

I have started using Activiti for a long time but recently I started seeing different behavior in explorer. When  I click on any process under process tabs, the body of the explorer is becoming blank. I have to try again clicking the process tabs then select a process. With couple of attempts like this, I am able to see the process workflow diagram.

Nothing is getting logged means no errors.

Nothing has changed recently that could explain this behaviour. I haven't experienced this myself.

Best regards,

I can confirm this problem when using Google Chrome. Seems like this is related to a Google Chrome Update. With Firefox, everything works as expected. The behaviour is reproducable with Chrome Version 43.0.2357.81 m

I am getting this error in chrome version 45.0.2414.0 dev-m.  No errors in the log. Looks like browser issue.

I am getting the same problem with Chrome 43.0.2357.132 m.

I just reproduced this issue but didn't find the cause. (changed the code until it stopped being reproducible).
(I removed completely the right panel with the process details)
If i add any component in the right side (just an empty container, or a Label) the issue could be reproduced again.

this make me think is a issue between Vaadin and Chrome since by adding an empty container in a grid causes this issue. (but still under investigation)

Creating a simple Vaadin application with a similar structure and layout could be a good idea.

Me too, having blank-problem with Chrome Version 43.0.2357.130 - Ubuntu 14.04.
IE 9/10/11 - Windows 7 is OK (but with IE 10 and 11 need running in the compatible mode)
Firefox is OK too.

My quick fix is to press F5 (or click refresh button) the problem is simply bypassed at this time, but next actions still came back.
Where are you, activiti-team. Please help us, it affects to my company at all sorry for my asking!

Thank Vasile.dirla
I wonder that do we need to upgrade the vaadin to the newest version? I think the ajax between them may be fixed in updated version.
