[TYPO3-english] problems reloading page tree from click menu

[Reinhard Führicht]

Hi guys,

I'm trying to fix the extension pagetreetools, so that it will be 
compatible with 4.2.

I fixed all problems except reloading of the page tree doesn't work.
If a user clicks to highlight a page/branch in the tree, the according 
class of pagetreetools gets called and does settings to adjust the CSS. 
After that the page tree should be reloaded so that the changes are visible.

In TYPO3 < 4.2 it worked this way:

$GLOBALS['SOBE']->content .= '<reloadcode>...</reloadcode>';

This code has no effect in TYPO3 4.2. So I tried to use a simple 
redirect using:

header("Location: ...");

Which didn't work either. After digging deeper into available functions 
I found t3lib_beFunc::setUpdateSignal(), which should do the job.

Unfortunately none of these tries works.

Has anybody an idea?

Regards,
Reinhard
