you must know that:
- there is no necessity for putting a thread in a group
- if you WANT or NEED to put it in a group, the procedure is the following one:
1 : create a threadgroup object
2 : when you create your thread (or thread extension) object, you have to call the constructor containing the threadgroup parameter
a reply was posted to show you how to proceed ; take a look at it
but keep in mind that there it's not an obligation to handle thread groups
