Event Structure's value change, not detecting changes when tabbing thru array of clusters

[Elsa Fung]

Hi!  I have an array of clusters (int, int, string, int) control, and want to detecting changes made to the it.  I used the Event Structure's value change case on the array, it works excellent except that it'll only detect the changes when you click out of the element or press the enter key (the one by the numbers, not carriage return).  I want it to detect the changes when I tab thru the cluster or array too, but I can't figure it out... Does anyone have any ideas?

Thanks!

It is better if you can post you vi here.

Here's a simplified version of what I have.  When you run the vi and the change value of the array of clusters, the event structure will only detect the value change (and pop the dialog message) when you click out of the element you changed or press the enter key on the element you changed.  But I want it to detect the change when you tab out from the element you changed too.

Thank you!!

I would use Mouse Down?

Sorry, I use LV7.1.  Can't open you vi.

check Key down and Key up event. , define the tab event.

On a sidenote, tab works fine in LabVIEW 7.1 using a simple "value change" event, so your observation seems to be a bug (or feature) specific to LabVIEW 8.0.

The bug is actually more serious. Try the following:

1. Change one element
2. tab to the next element
3. click outside

---> the "value change" does not register at all if you "click out of it" after a tab.

Tried Value Change with my example done in 7.1 and it doesn't trgger an event.  That is why I suggested Mouse Down.

Something else must be going on, I tried to duplicate the behavior in a new .vi and it works as expected in both 7.1 and 8.0

In a blank vi, I created two numerics, put them in a cluster, and put that cluster in an array.  I set up the event structure just as in Elsa's example.

It worked in both versions when I created it in 7.1 and it worked in both when I created it in 8.0

I am stumped.

Curious. I did a few minor edits in 8.0 before saving as 7.1, but the simple value change event got triggered just fine when the value vas terminated with a tab in 7.1. Every time.  Strange....

Are you on 7.1 or 7.1.1? Maybe there's a difference (I am using 7.1.1).
