Auto-Calculation of areas

Hi,

i am trying to Auto-Calculate the area while digitizing / editing a xfm-feature. I followed the description "Geospatial Administrator Tips and Tricks" but with no success.

using: Bentley Map / Geospatial Administrator 08.11.05.49

I tried the following steps, without success, no messages or error messages

any ideas?

In Geospatial Administrator

Ceate a Feature --> XY; Add Property --> MyArea
Add a New Initial Value for the Property
In "New Initial Value - Dialog"  --> key = edit | Sync Pref's = OFF | Value Type = cexpression | Value = [([XY.MyArea])]

After digitizing and editing the feature there is no Auto-calculation of the area!

Thanks

Burkhard
