Any solution should do, as long as we can call a method that blocks and
returns with the answer. I did try with a WAComponent also that embeds
the current component, but with similar results.
I will have a look at your code as mentioned in your other email too. In
the mean time, I have come up with something that works. Not sure how
idiomatic this is of seaside though:
WAComponent subclass: #DialogHolder "An empty
component that can be replaced by the dialog later"
WADecoration subclass: #DialogDecoration "A Decoration that
adds a DialogHolder to its decoratedComponent"
holder := DialogHolder new
html render: holder.
self renderNextOn: html
Then, the method that makes it appear, on a WAComponent subclass:
| dialog answer |
dialog := DialogDecoration new.
self session presenter addDecoration: dialog.
answer := dialog holder
self session presenter removeDecoration: dialog
