Urgent help required to make variableRowHeight & rowCount work hand in hand for a Datagrid

Question

HI,
I am using variableRowHeight property on a datagrid to wrap the text and this works perfectly.
At the same time, I have to assign rowCount dynamically. My logic for caluculating rowCount is rowcount = sampleData.length > 5 ? 5:sampleData.length; where sampleData is my ArrayCollection. The caluculation happens correctly.
The issue here is rows of the datagrid do not show correctly.
From the post http://forums.adobe.com/message/2350643#2350643 I understood that both variableRowHeight & rowCount do not work hand in hand.
So, I tried removing variableRowHeight and it works fine. The solution says using measureHeightOfItems and viewMetrics to calculate the height may solve the issue. I did not understand it very clearly.
Can anyone let me know the solution with example.

Hi,
have you checked your bindings not only for the WF --> Method, also for the Method --> WF?
Christoph
Of course I mean the bindings between Task and Method / Method and Task
