Order of Events

I need help (in many ways).  Does anyone understand the form event model  or see an error in the process below (which I have been using for 10 years)

What is the best method for opening a form to a specific record?

Currently,  on my menu, I have a tablegrid which lists hundreds of records.  The user can double-click any record to edit that record.

When that happens,  I perform the following steps

1. Open the edit form
2. attach a UIObject variable to the form
   1. Create a dynArray filter which has criteria to filter the specific record
   2. Apply the  dynArray to the UI object using SetGenFilter

3. set a few varaibles on the form

4. form is now open to the correct record.

My problem occurrs between step 1 & 2.  When Step 1 completes all of the events on the form and fields on the form fire. And Quite honestly,  I dont understand why the SETFOCUS or ARRIVE event of a field would fire until you actually setfocus or arrive at the field.

I must be missing something SO obvious!!!!!
