Happening to me a lot, too, strings of only ~10 lines are enough to slow down the performance considerably.

Happens in all files on translate.engineering I'm working on these days, a good example with plenty of long strings can be found here: https://translate.engineering.redhat.com/webtrans/Application.html?project=rhel_deployment_guide&iteration=6.2&localeId=de&locale=de# (Deployment Guide, file Package_Kit)

Gedit is my friend at the moment - I am forced to copy and paste my translation into the editor for a huge part of the messages in any given file - this not only slows down my productivity, but also means that all editor features like the translation memory are effectively worthless as I'm not using the editor at all for those strings.

Is this issue being adressed?
The original report was for 1.4.1, I am encountering it for Zanata version 1.4.5-alpha-1 (20120124-0107) on F16, using FF 9.0.1

Thanks

Note: This appears to be caused by the key shortcut implementation - disabling the key shortcut code for the editor allows extremely long strings (over 30 lines) to be edited without a noticeable delay in Firefox 3.6.18. There also appears to be some legacy undo/redo code that isn't properly disabled.

Comment 5 Alex Eng 2012-02-12 23:34:56 UTC

This caused by the autosize function on the textArea while input. This bug is related to https://bugzilla.redhat.com/show_bug.cgi?id=773510
