TYPO3 Core

why don't you just use the "layer_menu_id" property of TMENU_LAYER to get unique names?

Otherwise it seems to be the same as http://forge.typo3.org/issues/24367.

Looking at the related bug reports, I think using rand is a bad idea ( the problem was introduced when removing the use of microtime that caused a flooding by temp-files).

Probably the menu items should get enumerated and the enumeration used as part of the id.

I have tried "layer_menu_id" like described here:
http://www.typo3.net/tsref/menu_objects/gmenu_layers/
The "layer_menu_id" is valid for a whole level so the WMid is always the same.

IMHO TMENU_LAYERS should be deprecated instead of wasting time into it.
You can create much better menus with TMENU+CSS.

Kurt, can you reproduce this on older TYPO3 versions too?

Yes. I have this problem with Typo3 4.4.6 too.

If no layer_menu_id is given, the WMid will be generated like this:
substr(md5('gl' . serialize($this->mconf)), 0, 6);
It depends only on $this->mconf.
print_r($this->mconf) tells me this:

Array
(
    [layerStyle] => position:absolute;visibility:hidden;
    [lockPosition] => y
    [relativeToParentLayer] => 1
    [relativeToTriggerItem] => 1
    [topOffset] => 0
    [leftOffset] => 175
    [hideMenuWhenNotOver] => 100
    [hideMenuTimer] => 100
    [expAll] => 1
    [wrap] => <div class="menu1_main2_table">|</div> 
    [NO.] => Array
        (
            [allWrap] => <div class="menu1_main2"> | </div> 
            [ATagTitle.] => Array
                (
                    [field] => title
                )

        )

    [ACT] => 1
    [ACT.] => Array
        (
            [allWrap] => <div class="menu1_main2_act"> | </div> 
        )

    [IFSUB] => 1
    [IFSUB.] => Array
        (
            [allWrap] => <div class="menu1_main2_sub"> | </div> 
        )

)

A better solution: replace rand(0,99) with this:

$GLOBALS['TSFE']->register['count_HMENU_MENUOBJ']
