Hi all,
Once again I am hitting some unexpected behavior in IronRuby. Might be a
bug

animation = System::Windows::Media::Animation::DoubleAnimation.new()
=> #System::Windows::Media::Animation::DoubleAnimation:0x000005c
animation.Duration= System::Windows::Duration.new(
System::TimeSpan.FromSeconds(2))
=> #System::Windows::Duration:0x000005e
animation.Duration= System::Windows::Duration.Forever
=> #System::Windows::Duration:0x0000060
So far everything works as expected. Now trying to directly set a
timespan
which should be possible in C#:
animation.Duration= System::TimeSpan.FromSeconds(2)
:0: can’t convert System::TimeSpan into System::Windows::Duration
(TypeError)
ok, automatic conversion seems not yet to work here … but the next
thing
is really strange:
animation.Duration= System::Windows::Duration.new(
System::TimeSpan.FromSeconds(2))
:0: can’t convert System::TimeSpan into System::Windows::Duration
(TypeError)
animation.Duration= System::Windows::Duration.Forever
:0: can’t convert System::TimeSpan into System::Windows::Duration
(TypeError)
???
What has already worked now doesn’t any more, depending on the value
that
has been set before. You will probably know what is going on.
Cheers,

Crazy. I’ve opened a bug:
