Create a converter for dealing with lists
-----------------------------------------
Key: SEAMFACES-141
URL: https://issues.jboss.org/browse/SEAMFACES-141
Project: Seam Faces
Issue Type: Feature Request
Components: Validation & Conversion
Reporter: Brian Leathem
A converter is required to serialize an object into the query string for use as a view
param. If that object is a list, it would be helpful to make use of an existing converter
that converts each individual entry, and has the cumulative result serialized as a
string.
The standard CGI syntax represents arrays as multiple values, each with the same key.
This may already be supported in JSF, but at the time of writing this, I couldn't find
it.
