Hello all, I have array of Filter objects in my document. Filters are used in two ways: 1. I can select one of them to filter my data 2. I can browse them all and add, delete or/*modify any of them
My document exposes this array via -filters/-setFilters pair. I have two NSArrayControllers: one for the first task and another for the second task. Main window has NSPopUpButton that is bound to the first array controller. It is used to select filter. Window controller receives messages from this button and call -setFilter method of my document. Document filters data and all works fine, but I think there is a simpler way to "connect" my document's -filter property and to controller's selection. Is it possible? This is the first question. Other array controller used for editing filters. I have NSTableView bound to that controller that shows filter names and NSPredicateEditor that is bound to selection of the second array controller. It is used to edit filter. All works fine, but I can't receive a notify that current filter was changed. NSPopUpButton somehow knows that name of filter was changed and displays it immediately. But my document's -setFilter method didn't get called. -setFilters method didn't get called too. I tried to bind "filter" property of my document to the first controller's selection but it didn't work too. I wrote something like this in the main window controller: [[self document] bind:@"filter" toObject:pFiltersController1 withKeyPath:@"selection" options:nil] I even added +initialize method to the document and exposed "filter" binding. Nothing... Just some errors in log about "NSControllerObjectProxy predicate: unrecognized selector sent to instance ......" So the questions are: 1. How to bind some property of my document to selected object of NSArrayController? Or at least how to monitor changes of the selected object? 2. What is the correct way to do what I want (two different types of operations on one array)?
