MPxNode::setInternalValue -> element attribute update

I have an array attribute ('MFnAttritute::setArray(true)', which is set to be internal ('MFnAttribute::setInternal(true)').
When I now change the value of one element, inside the 'MPxNode::setInternalValue', I get the old value of that element,
even though the channelBox shows the new value and also asking Maya with 'getAttr( "myNode.myElemAttr" )' gives me the
new value. I have to set the value twice so that inside the 'MPxNode::serInternalValue' I get the correct updated value.

So, what am I doing wrong?
Thanks for help!

There´s one more problem with getting the right values from my array plugs, which were set to be 'internal'..
I can save the data for the elements with a normal Maya save file.
When I have a look at the '.ma' file the data are there.
But when I load the scene, the data are ignored and the array plugs have no elements.

So, either thats a horrific bug or I have ignored some fundamental code additions/changes.
