#751: Objects instantiated as anonymous class by Bindings mechanism

there is a problem with bindings mechanism in MacRuby 0.6 :
- create a new MacRuby Document based project
- MyDocument.nib
create a new ObjectController binded with File's Owner Content,
model key path "dummy"
create a new text field binded with ObjectController selection,
model key path "name"
- MyDocument.rb
{{{
class MyDocument < NSDocument
attr_accessor :dummy
def init
super
setDummy({"name"=>"dummy"})
puts "in init class of Hash is :
#...@dummy.class.ancestors}"
return self
end
def windowNibName
'MyDocument'
end
# Document data representation for saving (return NSData)
def dataOfType(type, error:outError)
puts "in save class of Hash is :
#...@dummy.class.ancestors}"
return true
end
# Read document from data (return non-nil on success)
def readFromData(data, ofType:type, error:outError)
return true
end
# Return lowercase 'untitled', to comply with HIG
def displayName
fileURL ? super : super.sub(/^[[:upper:]]/) {|s|
s.downcase}
end
end
}}}
bindings works, but when i try for to save the document, or already in the
windowDidLoad (NSWindowController) method...
{{{
in init class of Hash is : [Hash, NSMutableDictionary, NSDictionary,
Enumerable, NSObject, Kernel]
in save class of Hash is : [#<Class:0x200577420>, Hash,
NSMutableDictionary, NSDictionary, Enumerable, NSObject, Kernel]
}}}
of course if i try to serialize the object i obtain :
{{{
`fileWrapperOfType:error:': can't dump anonymous class #<Class:..........>
(TypeError)
}}}
if i remove the bindings with text field all works again...well i mean no
data in it, but at least the class of object remain the same
as workaround i can create the hash via NSMutableDictionary.dictionary or
in my case :
{{{
temp = YAML::load( NSString.alloc.initWithData(
fileWrapper.regularFileContents,
encoding:NSString.defaultCStringEncoding))
@data = NSMutableDictionary.dictionary
@data.setDictionary(temp)
}}}
