Deleting the pointer of the allocated chunk is what is surely wrong.
Aside the rules set by Palm (which define how triggers/fields hold and
manipulate data) there is something that should be bothering you
additionally in that code: setting a simple buffer should not be that hard,
right? I mean, in the worst case, you should simply be able to use
char s[MAX_ITEM_PRICE_SIZE] and not bother with allocating dynamic memory.
If you *have* to allocate dynamic memory, it is often because you want it to
stay around for a while.

Subject: Trigger label changes bombing
When I change the label on a popup trigger with this:
{
CharPtr s = MemPtrNew(sizeof(char[MAX_ITEM_PRICE_SIZE]));
MemSet(s,MAX_ITEM_PRICE_SIZE,0);
s = StrIToA(s,qty);
CtlSetLabel(GetObjectPtr(ItemEditQtyPopTrigger),s);
MemPtrFree(s);
}
and then try to use the popup trigger on the form, I get an error reading
from an unallocated chunk.
What am I doing wrong?
