[HTML_AJAX-devel] Problem synchronizing Ajax calls

[JavaRunner]

I have a JSP that renders up to 6 SELECT elements. Each SELECT is dependent
on the preceding SELECT.
At startup the app grabs a default value for each SELECT and uses this value
to pre-select an option.
This option value then becomes a retrieval argument value in a SQL stmt that
retrieves data for the following SELECT.
My problem is this:
After the first Ajax call the functions containing the next Ajax call is
firing before the code to pre-select the preceding SELECT has completed.
Hence an incorrect argument is passed to the SQL.
I have tried using setTimeout but IE gets in the way and reports 'Slow
running script bla bla'. Setting various Advanced IE options
suggested by several Google searches hasn't helped. One suggestion involved
setting a Registry entry. That did not work either, and
since this is commercial software it's difficult to ensure all users make
the necessary Registry changes even if it had worked.
I've also tried setInterval. This will fire a function that can test for a
specific variable value that I can set when the
scripts have completed, and then I clearInterval when I find the value has
been set.
This doesn't work too well either.
Using IE is mandatory in this case. :evil: :evil:
Any one have any suggestions that might resolve this issue?
