[Geomoose-users] Setting initial conditions

[Brent Fraser]

Bob,

   Thanks for the info.  I did a little experimenting and found out that 
"a Service with a user input type pointing to a user extension with a 
setValue function" will indeed work.

So now I have a URL of
geomoose.html?call=set_combobox&option_id=1

and a service of:
<service name="set_combobox">
<input type="ga_set_combobox" name="option_id" value="0"/>
</service>

with a user extension function of:
     GeoMOOSE.Services.InputType.SetComboBox = 
OpenLayers.Class(GeoMOOSE.Services.InputType, {
         MAPBOOK_NAME: "ga_set_combobox",
          setValue: function(option_id) {
     // ----      TBD: Code to set combo box selection    -----
         }
     });

The Chrome debugger says option_id = 1 so I think I'm good to go...

I'm basking in the awesomeness of GeoMoose!

Best Regards,
Brent Fraser
