Hello,

I have recently started to working with p.mapper. But after a while I get
into problems how to continue working with it.

I tried some functionalities, especially about drawing plugin (in dialog of
drawnig I added code to save polygon/point to database and make available
load it again - showing it on map). The first problem appeared here, because
one object (polygon/point) is loaded multiple times. I need to restrict it
to be on map only once.

The next thing I need to do is to create one layer for polygons and when
drawing, append all of the polygons to it. This layer must be shown on TOC
(on right side menu) and there must also be checkbox with use of
enable/disable (show/hide) this layer. I also found an example of what I
want to have implemented. It's on following link:
http://www.sig.camacari.ba.gov.br/urbam/map_default.phtml.

I hope you can help me.

King Regards
