Hi,

The CONCAT function in the FDO expression language is difficult to use in many cases because it supports only two parameters. If you need to concatenate a set of more than two strings, you have to use nested calls which is not convenient and error prone.

RFC 22, drafted by Dan Stoica, proposes to support a variable set of parameters for this function to make it easier to use.

http://trac.osgeo.org/fdo/wiki/FDORfc22

Have a look at the RFC and provide your comments.

Thanks,
Orest.
