How to pass data to IBAPickListFormField?

[Costa]

I am having difficulties passing the saved NSString data to the
IBAPickListFormField.
All the other form field types seem to work OK (incl. Date Picker).
I tried setting it directly, tried thru Core Data model binding, the
result is the same: it crashes on the function that is returning the
NSString value, even setting the label yields the same.


- (NSString *)formFieldStringValue
{
NSString *value = nil;

if (self.formFieldValue != nil)
{
NSMutableArray *itemNames = [[[NSMutableArray alloc] init]
autorelease];

for (id<IBAPickListOption> item in [self pickListOptions])
{
NSString *itemName = [item name];
if (([[self formFieldValue] containsObject:item]) &&
(itemName.length > 0)) //crash
{
[itemNames addObject:itemName];
}
}

value = [itemNames componentsJoinedByString:@", "];
}

return value;
}


Am I doing something wrong?

Set breakpoints within your pick list value transformer, and see how you go from there.

I did. I found the answer in another topic.

Frankly, I find it strange if a property whose value is stored as String cannot be passed a String as a parameter.

Hi,

I'm having the same problem to set the initial value for IBAPickListFormField. Can you show me how you solved it? 

Thank you very much.
