[Users] How to prevent a node from having radiobutton?

[Robert Buckley]

I have a subdirectory in a tree that should contain one raster layer which SHOULD NOT be queryable, and one vector layer which SHOULD be queryable.

I can only define the container to either have a radiobutton or not, but how can I have one with and one without??


Here is how I define the tree branch

{
nodeType: "gx_overlaylayercontainer",
id: "gx_ovContainer_fnp_bsk",
text: "FNP Stadt Braunschweig",
expanded: false,
loader: {
filter: function(record){
// return record.get("layer").name.indexOf("Luftbilder") !== -1
return record.get("layer").options.themeId == "fnp_bs";
},
            baseAttrs: {
                radioGroup: "infoLayers",
                uiProvider: "layernodeui"
           }
}
}


Thanks for any tips,

Rob
