Hi,
i spent a little time with the problem i had some time ago, in effect 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 to save the document...
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
au contraire in MacRuby 0.5 all works fine
in init class of Hash is : [NSMutableDictionary, NSDictionary, Enumerable,
NSObject, Kernel]
in save class of Hash is : [NSMutableDictionary, NSDictionary, Enumerable,
NSObject, Kernel]
Thanks for any help and workaround
Ciao
