[Mapbuilder-users] Add layer on the mainMapPane

[<car...@gm...>]

Hi all.
I want to add layer on the mainMapPane?
I observed the function
"javascript:config.objects.mainMap.setParam('deleteLayer','prov_bound');",
on the sample
http://localhost:8080/mapbuilder/demo/contextEditor/index.html<http://localhost:8080/mapbuilder/demo/openlayers/index.html>

It can be made?

Help me.
Best regards,
Carlos FG
