[TYPO3-core] FYI: Fixed bug #12421: htmlArea RTE: Paste is erratic in Opera 10 when server-based cleaning is enabled

[Stanislas Rolland]

FYI: The attached SVN patch was committed.

Type:
Bugfix

Problem:
When Opera is used and server-based cleaning is enabled, if one presses 
Cmd+V (Ctrl+V on Win), the text is inserted a few times, but after that, 
it's inserted and immediately removed.

Server-based cleaning is performed by posting a synchronous request to 
the server. However, Opera does not, like all other browsers, inhibit 
input while the synchronous request is being processed.

Solution:
The attached patch inhibits key events in Opera while a synchronous 
request is being processed.
