More than one listener seems to stop Master-Detail events working.

I have an analysis A that sends master detail events on a channel called country_chan.

I have another analysis B that listens to the country_chan and will update its display if I change to a different country on a bar chart on A.

When I add another listener (Analysis C) neither analysis updates in response to changes on A.

I have tried having separate channels eg: country_chan_a, country_chan_b on Analysis A so that B listens on country_chan_a and Analysis C listens on country_chan_b but this does not work either.

Does anyone know if having multiple listeners on the same channel works in OBIEE 12 ?

    Are any of your analyses unions?  I work in 11.1.1.9.5, but I've found that that can cause problems for master-detail linking.
    This may not be your problem, but if it is, the solution I've found is that the channel has to be established in the original "leg" of the union, before other queries are added in.
