Tree decomposition visual With Field Parameters it only expands two levels and crashes on the third.

Hi, saravanan7777 

I have the same error when using field parameters with the decomposition tree. If I have three explanatory fields, being each of them a field parameter (see image below). Visual crashes after trying to expand to the third field.

Any thoughts/workarounds?  I would like to let the user to select which level of detail he desires for each of the steps in the tree.

i.e. 
Step 1: 
-Region_1
or Country_1
or City_1

Step 2:
-Region_2
or Country_2
or City_2

And so on...
