I've not been able to reproduce this... can you please provide more information as to the exact steps required to reproduce this problem please. E.g. exactly what buttons are being clicked, what settings are being set, whether or not the document makes any difference, etc

I still can't reproduce this either on a local build or even on the live MyAlfresco site... I've tried the attached documents but I'm not able to break this page. I think this is quite an edge case - maybe a video should be uploaded to show exactly what is required to break the page (e.g. the speed at which the changes need to be made). We also need to evaluate the likelihood of this being hit by real-users. Therefore I'm also lowering the priority.

Please see the following file: ftp://ftp.alfresco.com:21/qa/cloud/ace-1834/chrome.zip
The file contains video file.

The issue is reproduced for cloud2 myAlfrescoHead build 497 rel36rc2.

Dmitry Yukhnovets [X] I thought the problem was the the overall page got corrupted (your attached screenshots show that the sidebar is missing. If this is just an issue with some poor rendering of text between browsers in a 3rd party library then then isn't really much we can do about it. So I would consider that this isn't really a bug. The previewer is just a previewer, it's not a full document renderer. Unless there is some other issue then I think this can be closed.

My mistake... the video contains info about reproducing : ACE-1833.
i will capture video for reproducing ACE-1834.

Comment by Dmitry Yukhnovets [X] (Inactive) [ 28-May-14 ]

it's difficult to reproduce (at least for me) - but i was able to reproduce it and capture video. please see: ftp://ftp.alfresco.com:21/qa/cloud/ace-1834/ACE-1834.zip

Having reviewed the video, I would strongly recommend that we don't consider this to be blocking R36 and focus on issues that will be genuinely blocking.

Will Abson & Kevin Roast [X] You should probably review the 2nd video and add your input.

This is not a issue worth the development effort to fix.
