Problem with WPF animation.Duration= and TimeSpan


#1

Hi all,

Once again I am hitting some unexpected behavior in IronRuby. Might be a
bug
:wink:

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:
