Load register inside TMENU - typo3

Question

In a TYPO3 HMENU, the second level TMENU should reproduce the abstract of the first level page.
I do manage to fill the register with a value and use it in the second level TMENU - but I am unable to load the field's content into the register.
So
field = abstract
as well as
value = {field:abstract}
value.insertData = 1
don't produce any output.
How can that register be filled with the parent page's abstract?
Here's the full code.
temp.main_nav = HMENU
temp.main_nav {
wrap = <nav id="cbp-hrmenu" class="clearfix cbp-hrmenu span12">|</nav>
entryLevel = 0
1 = TMENU
1 {
noBlur = 1
expAll = 1
wrap = <ul class="level1">|</ul>
NO {
wrapItemAndSub=<li>|</li>
before.cObject=LOAD_REGISTER
before.cObject{
parentAbstract.stdWrap.cObject=TEXT
parentAbstract.stdWrap.cObject{
field = abstract
#value = {field:abstract}
#value.insertData = 1
}
}
}
}
2 < .1
2.stdWrap.dataWrap = <div class="cbp-hrsub"><div class="cbp-hrsub-inner"><div>{register:parentAbstract}</div><div><ul class="level2">|</ul></div></div><!-- /cbp-hrsub-inner --></div><!-- /cbp-hrsub -->
}
PS: {levelfield} seems to be problematic inside a TMENU, that's why I switched to LOAD_REGISTER

Answer 1

Solved it.
The problem was in
2 < .1
The second TMENU inherited the load_register from the first one and kept filling it. That's why there was a wrong abstract (e.g. an empty one) in it.
Here's the working code:
temp.main_nav = HMENU
temp.main_nav {
wrap = <nav id="cbp-hrmenu" class="clearfix cbp-hrmenu span12">|</nav>
entryLevel = 0
1 = TMENU
1 {
noBlur = 1
expAll = 1
wrap = <ul class="level1">|</ul>
NO {
wrapItemAndSub=<li>|</li>
before.cObject=LOAD_REGISTER
before.cObject{
parentAbstract.cObject=TEXT
parentAbstract.cObject{
field = abstract
}
}
}
// EDIT: if you have additional states, don't forget to add the abstract too
ACT < .NO
ACT = 1
ACT {
wrapItemAndSub=<li class="dropdown active">|</li>
}
}
2 = TMENU
2 {
noBlur = 1
expAll = 1
stdWrap.dataWrap = <div class="cbp-hrsub"><div class="cbp-hrsub-inner"><div>{register:parentAbstract}</div><div><ul class="level2">|</ul></div></div><!-- /cbp-hrsub-inner --></div><!-- /cbp-hrsub -->
NO {
wrapItemAndSub=<li>|</li>
}
}
}
