SQLEncoder cant handle some conversions
---------------------------------------
Key: GEOT-1088
URL: http://jira.codehaus.org/browse/GEOT-1088
Project: GeoTools
Issue Type: Bug
Components: data jdbc, data postgis
Reporter: Justin Deoliveira
Attachments: SQLEncoder.java.diff, SQLEncoderPostgis.java.diff
SQLEncoder as written will choke on filters such as:
<Filter>
<PropertyName>booleanProperty</PropertyName>
<Literal>1</Literal>
</Filter>
The fix is to have the sql encoder evaluate literals in the context of a type,
which is available from the PropertyName while encoding a filter.
The new geoapi Filter interface offers a nice way to acheive this as visitor
methods can return "data" or hints as a filter is traversed. However the jdbc /
postgis datastore is very tied to the old SQLEncoder interface ,so changing
over would require all jdbc based datastores to shift, which is a problem. So
for now, i am stuck with hacking the current.
Patch attatched for review.
