Hi Mark,

The Edit button Luca is referring to is the one in the launch 
configuration dialog in the Overview sub-tab of the Profiling tab. Here 
you can pick a profiling set (e.g. Execution History), create your own 
set, or edit an existing one. The Edit button was somewhat hard to find as 
it wasn't next to the Add or Remove buttons, so it was moved in 3.2.

Editing a profiling set lets you pick which profiling types you want - a 
profiling type is a type of data that you want to profile, like memory, 
performance/execution, or code coverage. If you click Next in this wizard, 
you can pick the filters to use, and check to make sure the default 
filters aren't filtering out your classes.

If you still don't get data, here are a few things to check:

1. If you're looking at the execution flow and sequence diagram views 
(class interactions, etc), these won't be populated unless you select the 
"Show graphical flow data" option in the execution history profiling type. 
Select the Execution History and click Edit, select Execution Time 
Analysis in the tree on the left. If you want object interactions, you 
have to also pick "Show instance level data". These are turned off by 
default because they are too CPU and memory-intensive for larger 
applications. If you just want statistics, use the method statistics view 
(or execution statistics in 3.2).

2. Make sure your code is in fact being called.

Let me know how it goes..

Thanks,
Curt
