Hi,

is it possible to return "synchronously" even if I have an asynchronous message?

For example:

SomeObject>>someMethod
�� ^ UIManager default chooseFrom: #(a b c)

When the above method is executed, it will open a popup and block the execution until I select something, then it will return the selection.

But if I instead have something like this

SomeObject>>otherMethod
�� |choice|
�� NewListModel new
�� items: #(a b c);
�� whenSelectedItemChanged: [ :item | choice := item ];
�� openDialogWithSpec.
�� choice.

Then it will open the window but it will immediately return nil.

With a spec window, you can try to open it modal

WindowModel>>#modalRelativeTo: aWindow

So my question is: is it possible to synchronously return even in the second example / block the flow until a selection is made?

Thanks,
Peter
