FeaturePanel_AttributeForm

[adube]

Brief description

This will be an new "FeaturePanel" widget that will automatically build the form fields from the attributes of the vector features it wants to edit.

Some features

• supported by both XML and DB configs
• Only textboxes
• No pre-defined values
• No field validation
• No read-only

Less flexibility, more magic and simplicity.

More details

• The !FeaturePanel_Form would be too hard to implement in the PGSQLMapContextConfig driver. That is the main reason for this new widget.
• If we had a WFS service, we could have used the GeoExt.data.AttributeStore to automatically populate the fields with a standard DescribeFeatureType request instead. Since it's not the case, we'll leave that for later.

Issue

Unfortunately, it won't be possible to always auto-detect the fields. For already existing features it's working, but for new features, the attribute array is empty. They need to be specified somehow.

If we used WFS, we could do a DescribeFeatureType request, but we're using FeatureServer and there is no such equivalent thing we can use. For that reason, we can't use the 'auto-detect' fields feature.

Solution

It's out of the question to switch for WFS for now, so we'll have to specify the fields in the Resource. In the PGSQLMapContextConfig, it's already supported, but no in XML. We'll have to add it.
