This field would a combobox whose values could be fetched when the
combobox is open.

FYI, we have an extension for feature editing using a grid,
GeoExt.ux.FeatureEditorGrid. You may want to use it, or get some
inspiration from it. See
<http://trac.geoext.org/browser/extensions/geoext.ux/ux/FeatureEditing/lib/GeoExt.ux/FeatureEditorGrid.js>

> 2-      It is required to integrate the geometry features with MIS application, which means that the geometries will be stored in one table and the attributes will be collected from another one or more tables. But still it is required to view these attributes and use them to query features. For example, customers location are stored into customer_locations table, the debits for the customers are stored in customer_depits table, of course customer id is a one-one relationship between the two tables. From the GIS I need to show the debits of each customer and search for customers who have debits greater some value.

You'll have to create specific web services for that. MapFish is good
at that :-)
