[Xsltforms-support] selection of default value in select1

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

The xform below contains my solution to selection of default values in select1 lists, note the 'set-selected' custom action that gets fired by the 'xforms-ready' event.

This is working in firefox but there are some problems in IE that will probably be fixed by upgrading to a newer version of xsltforms. 

Constructive criticism welcomed.

Note that I am using a Web Feature Service (WFS) as my backend data source/sink.
