Filters Not Working

While trying to get date-based themes to work, I've come across another
problem (a bug maybe) with Filters. If I enter a condition for a theme
such as Field < AnotherField this works as expected. If the same
condition is put into a Filter on the same layer, no data is displayed.
I'm assuming this means an error has occurred, but no error message is
returned.

The Studio Help suggests that the expression dialog box for the Filter
and Theming is the same, and it makes sense that it would be. So I would
expect a condition to work equally well in both.

Another oddity I've come across is when using the 'Get' button in the
expression dialog box. This should return a list of unique values for
the selected field. However, I get an error message titled 'Unable to
complete request to site' and the message 'Parameter was not found:
Fieldname' when accessing data (via a feature join) in a SQL Server
table. The condition itself does work when used in a theme. However, if
I use the 'Get' button with fields in a different SQL Server table, but
in the same database, I do not get this error message. I can see no
reason for this.

All these types of issue make it a slow and painful process trying to
set up a working application.

Sure would be nice if somebody (especially somebody from Autodesk) could
shine some light on these things...
