Currently only some URL parameters (eg. any=corine) could be used to
populate the search form on application startup. Instead of that, it's
better to make the search form stateful and use Ext.state.Provider to be
able to restore the state of the application.
In order to be able to restore search state create a !SearchFormPanel
widget.
State must be saved:
* on search
* on reset
State consists of saving:
* all search form fields values (including spatial filter)
* search status (triggered or not)
This state could be use with a !GeoExt permalink provider to display
current search permalink:
{{{
// set a permalink provider
permalinkProvider = new
GeoExt.state.PermalinkProvider({encodeType: false});
Ext.state.Manager.setProvider(permalinkProvider);
// update link when state chnages
var onStatechange = function(provider) {
var l = provider.getLink();
Ext.get("permalink").update("<a href=" + l + ">" + l +
"</a>");
};
permalinkProvider.on({statechange: onStatechange});
}}}
