We're converting our Mapguide Enterprise software from v6.5 to 2010, but running into a problem. In v6.5 you could easily filter on the secundary table with the function 'SetWhereClause'. A very usefull feature for us.
But now it looks like this feature is gone in 2010. You can set a selection, but that is not what we want. We want to filter the data, displaying only the ones mathing the criteria.
