Hi, really I need to know if I can start a specific dialog and not work
on the current dialog. For example:
Boolean DialogHelper.canIStartDialog(String dialogName)
Or something else I can use to know if a dialog exists.
There is no current API that can answer the question "is dialogName a
name of a valid dialog definition", nor is there any way to ask for
all the defined dialog names. Both of those seem like they might be
useful additions ... could you file an RFE in the issue tracker?

If the question was "how to figure out if there is an active dialog,
when using basic impl", the code snippet Craig posted below is
implementation agnostic (will work for both dialog implementations
available in Shale 1.0.4).
