Jeff,

I solved problem. This error appears because in Control panel>Regional and Language options > Regional options I have set polish language. After change language to english(US) everything working good. But there is still problem, that I have to change the language.

I'm using the same PowerMap as you and windows XP Prof. SP3

Adrian,

What version of Bentley PowerMap are you using? Using Bentley PowerMap V8i 08.11.05.18 I was able to load and run the areas1.xml schema you had attached to your post w/o any errors.

Hi,
I'm using PowerMap v8i and unfortunately I have problem with cexpresion and expressionEvaluator. When I use Your Area1.xml, instead of some value, I get "Expression handler error: -1". However I use expressionEvaluator e.g.: key = editing | Synch Preference = OFF | Value Type = expressionEvaluator | Value = Zone.Area or ( [Zone.Area], (Zone.Area), [([Zone.Area])] ), I get nothing ,but in PBA I have: [Zone.Area] and this value is display.

I don't now if I doing somthing wrong or PM :)

regards

adek

Burkhard,

Thank you for the confirmation and I've updated the Geospatial Administrator Tips Tricks Wiki article with the "editing" key correction. Also you might be interested to know that the Bentley Map V8i SELECT Update release coming later this year will have automatically calculated geometric properties (e.g. area, perimeter, length) for all polygon and linear feature instances, including collections.

Jeff,

thanks, it works!

There is a mistake in the documentation "Tips and Tricks ..." in the "Initial Value Dialog field key" you have to type in "editing" instead of "edit".

I work with an english Version of Bentley Map on a german VISTA. There are some problems in calculating the correct area and length, to solve this problem i have to turn the system parameter from Germany to US (english)

Thanks

Burkhard

Burkhard,

For your MyArea property, the initial value, editing key, the cexpression should be [XY.Area] rather than [XY.MyArea]. Attached is an example schema with a single feature class "Zone" which has a single "MyArea" property that automatically calculates acreage during edit operations.
