Hello, thnaks for your help, Jon,
So I have a lot of this working now, but I have a problem!
I created a XIB with one window, several views. When a user clicks on the
object in the main view this happens:
- (void)showPropertiesWindowFor:(KRSimFlowElement *)flowElement {
FlowElementsPropertiesWindowController * propertiesController =
[[FlowElementsPropertiesWindowController alloc]
initWithWindowNibName:@"FlowElementsPropertiesWindows"
owner:flowElement];
[propertiesController showWindow:flowElement];
}
(I know the memory management here is a bit iffy ;))
then the controller does this:
- (void)awakeFromNib {
if ([[[self window] delegate] isMemberOfClass:[KRSimAssimilator class]])
{
[[self window] setContentView:assimilatorPropertiesView];
}
if ([[[self window] delegate] isMemberOfClass:[KRSimReserve class]]) {
[[self window] setContentView:reservePropertiesView];
}
}
The problem is that these properties are for core data entities. I set up
bindings for each view separately, but each entity has different attributes.
When I try to load properties for one entity other views complain that that
entity is not key value coding-complient:
[<KRSimReserve 0x1ba0d0> valueForUndefinedKey:]: the entity KRSimReserve is
not key value coding-compliant for the key areaSpecificIngestionRate.
Is there a way to salvage my structure or will I have to separate each
property view to it's own XIB?
Thanks a lot,
Karolis
