Description Hi,

other test that i've done :
- the stack overflow appear also in other program that worked previous of the last update
- deleted all the jvcl and jcl directory and re-downloaded all. Same problem
- done 2 revision downgrade. Same problem
- deleted all. Copied an old version. All worked well as before !
- upgraded only JvDBLookup.pas from the current SVN. All worked well ... but the component don't do automatic refresh as stated in the resolve of 5190. I need to call the ForceDisplay procedure that i've seen it's included in the current branch.

my conclusion: the problem is elsewhere in the upgrade of the jedi component and not in the new JvDBLookup.pas but it's a severe problem because i can't upgrade all the svn now ...

i've had the time to do some other test :
- Deleted all an re-downloaded to the current svn
- installed jcl and jvcl
- tested the program attached in 5190 (after commented out the ForceDisplay), result : stack overflow !
- downgraded only the JvDBLookup.pas to the revision 12723
- tested the program attached in 5190 (after commented out the ForceDisplay) result : all goes well, doesn't crash (but the bug of 5190 is not fixed in this version)

so my previous conclusion was not correct :-)
the is really in the JvDBLookup.pas

I do the same, no more stack overflow.
Thanks for your time

Fixed in SVN.
The "Locate" that is executed by the grid started a endless recursion of DataLink events.
