[FlexJS] Issues with casting to an Interface
Hi,
I continue exploring FlexJS and have following issue wich is hard to explain
for me:
I would like to decouple the view from the rest of my app using interfaces.
With the swc version all works fine, with the js versions it doesn't (0
errors, 0 warnings).
It seems to me that the js version doesn't like it if an interface is given
instead of the view that implements this interface. As soon as I try to cast
to an interface the js version refuse to work.
Perhaps at least it makes no sense to cast to an interface?
I have the following parts:
Main.mxml:
The application file that put it all together.
At applicationComplete event the method setData() is called tree times.
MyInitialView.mxml:
A minimial view that implements IViewMyInitialView.as
IViewMyInitialView.as:
An interface that contains only one method declaration:
setData(data:String):void
TestClass.as:
Expects the interface as constructor argument and implements a getter that
returns it
I pasted all parts with its code into one gist cause probably the code is
better formatted there:
https://gist.github.com/ok-at-github/8c4b94817fde72202231
Thanks for reading and sorry for posting so much probably confusing text. I
tried to reduce it all as best as I can.
Any ideas?
Thanks,
Olaf

Hi Andy,
>Which version of FlexJS are you using?
One of the earliest 0.6.0 builds, so it could be some months old.
>There were bugs with the cross-compiled "as" and "is" operators in 0.5.0
and older versions, but it should >work correctly in the nightly build.
Glad to hear that it might work with the latest build! Unfortunately the
installer doesn't work properly using the company network so I'll looking
forward to do this later at home.

Thanks for pointing that out. In despair of getting it work I tried anything
;-)

Alex has fixed the issue and I've just tested it using the nightly build
(20160322) without success.
Probably the fix did not make it into the latest build so I'll wait to the
next build.
Cause I'll probably off from tomorrow afternoon for a few days it will take
some time.
Thanks for help,
Olaf

Hi Olaf,
The "as" operator is working correctly, but it seems that there is a bug
where the compiler does not respect the implements="..." attribute in MXML.
That information is not being included in the MyInitialView.js output:
MyInitialView.prototype.FLEXJS_CLASS_INFO = { names: [{ name:
'MyInitialView', qName: 'MyInitialView' }] };
Do you want to create a JIRA issue for this?

I've just installed the nightly build (0.6.0, build 20160321) but it doesn't
fix the issue :-(
Is there a way to make sure that the "as/is" bug is really solved with this
build?
Thanks,
OLaf

Ha, can't believe it: Just removed this not needed "as IViewMyInitialView"
and... it works! :-)))
Thank you!!!

Which version of FlexJS are you using?
There were bugs with the cross-compiled "as" and "is" operators in 0.5.0
and older versions, but it should work correctly in the nightly build.
In this particular case, you can remove the "as IViewMyInitialView" in the
"get view()" function [1] since it's not needed.
