I have a form with about 30 UI elements on it, including three popup lists.
The app was working fine with no memory leaks, passing the 1 million Gremlin
test, etc. I tried to add a fourth popup list to the form and started
getting bus errors requiring a soft reset on the emulator whenever I tap one
of the buttons to popup a modal form. If I remove the fourth popup trigger,
all the problems go away.
Is there a maximum number of UI elements for one form
My (archaic, I know) setup:
CW Pro 5 running on Mac OS 9.2
MW IDE 4.2.5
Palm OS SDK 4
Large code model
Static lists associated with all of the popup triggers.
Identical code for setting and getting the selection of each list on form
initialization and close:
for setting the
// Set the case type trigger and list.
lst = GetObjectPtr (MtbxEditAnestypeListList);
ctl = GetObjectPtr (MtbxEditAnestypePopTrigger);
if (recordP.iMtbxIntVar[mIntProcType] != noChoiceSelected)
{
LstSetSelection (lst, recordP.iMtbxIntVar[mIntProcType]);
label = LstGetSelectionText (lst,
recordP.iMtbxIntVar[mIntProcType]);
CtlSetLabel (ctl, label);
}
else
{
LstSetSelection (lst, noChoiceSelected);
label = LstGetSelectionText (lst, noChoiceSelected);
CtlSetLabel (ctl, label);
}
for saving the changes:
// Compare the case type in the dialog with the one in the record.
// Update the record if necessary.
lst = GetObjectPtr (MtbxEditAnestypeListList);
lstChoice = LstGetSelection (lst);
if (lstChoice != noListSelection &&
packedRecP->iMtbxIntVar [mIntProcType] != lstChoice)
{
DbChangeRecord (ASTv3DB, &CurrentRecord, mtbxProc, mIntProcType,
&lstChoice);
dirty = true;
}
