Re: [OpenMap Users] Question Regarding an Error Message When Loading Shapefiles

Hi Piotr,

I'm hoping that the recent changes in the beta version of OMGraphics
will help this cause, where OMGraphics can store attributes. I'm
working toward enabling the different ShapeLayer classes to have the
option of loading the dbf file contents into their particular
OMGraphics, so the lookup and text location would be much easier.

If someone would contribute existing code that did this, though, it
would be appreciated by many people.

Cheers,

Don
