* Gorm.m: Removed code in the testInterface: method to allow
|
||||
NSBrowser, NSTableView, and NSOutlineView display correctly in
|
||||
testing mode.
|
||||
* GormDocument.m: Moved the code in loadDocument: into a NS_DURING
|
||||
block to catch any exceptions thrown during loading of a .gorm file.
|
||||
This will facilitate recovery of the application when a problem is
|
||||
encountered while loading the file and will allow the user to continue
|
||||
using the application despite the issue.
