A form field that holds an entire gxp.Viewer. This field is used to process geospatial information in forms. By itself, this field does nothing but showing a map viewer in a form element, aligned with field label and suited for an Ext.layouts.FormLayout.
To actually have this field’s textarea populated with information, a plugin accessing the additional field property that this component adds to its gxp.Viewer instance is required. See gxp.plugins.FeatureToField for a basic plugin that does this.
