[TYPO3-english] TYPO3 4.4.2 RTE very slow compared to 4.3.2

[Jochem Nabuurs]

Hi list,

In a custom extension we are using about 8 RTE's.
Because of the large amount of fields, I use the dividers2tabs option to 
create 5 tabs in the extension. On the 2nd last tab 4, RTE's are loaded 
and on the last tab another 4 RTE's are loaded.

When creating or editing a record, only the last RTE is working. The 
others are loaded, but I cant edit their content.When I save the record, 
all RTE's on the current tab are editable, but RTE's on another tab are 
only editable when saving the record while that tab is active.

When I disable the use of tabs (and all fields are loaded below each 
other, creating a very long list) all RTE's are editable (so no problem 
there).

I created the extension in a 4.3.2 installation, and enabling the tabs 
option there does not cause any trouble. RTE's are loaded very fast and 
are editable at all times.

I hope someone can help me with this issue because this extension has to 
go live in 1 day from now, and I really like to use the tabs function.

Thank you in advance!
