I have an interesting dilemma that I can't quite peg down. I have a grid on a pageframe that is bound to a view. (The grid is a list of members who are registered for a convention). The view is called 'members_for_convention' and is just a list of names from an intersection table between two tables: member, and convention, whose WHERE clause specifies only records for the selected event (convention).

The problem is, when cancelling a member from the convention, the grid only refreshes to show the changes after requerying twice. Here is the code behind the cancel button and the called method:

cancelbutton.click:
_____________________________________
answer=MESSAGEBOX("Are you sure you want to cancel " + alltrim(memb.fname) + " " + alltrim(memb.lname) + " from the convention?",48+0+1,"Delete")
if answer = 1 then
if seek(members_for_convention.membconvnum, 'membconv','membconvnu')
delete in membconv
endif
if memb.reason = "CONVENTION" then
delete in memb
endif
thisform.refreshpage4
thisform.refreshpage4 && Adding this line was the only way to get it to work
endif
_____________________________________
method: refreshpage4
m.convnum = convention.convnum
requery('members_for_convention')

seek members_for_convention.membconvnum in membconv order membconvnu
seek members_for_convention.mmembnum in memb order membnum
thisform.refresh

I have implemented many forms like this, and never had this happen. What could be different the second time that the method runs that would cause the grid to finally refresh?
