[Users] Fwd: Tree Node with Radio Button

[Andreas Hocevar]

Hi,

a LayerNode should not have a loader. Either you configure a container node (Ext.tree.Node) with a loader, or you configure individual layer nodes (GeoExt.tree.LayerNode) with attributes. In the latter case, instead of

loader: {
    baseAttrs: {
        radioGroup: 'theme'
        uiProvider: 'layernodeui'
    }
}

you would just configure

radioGroup: 'theme',
uiProvider: 'layernodeui'

For testing, you can also remove the uiProvider config option.

Regards,
Andreas.

I need to include two layers inside the same parent node but i would like to have one of them rendered with a radio button an the other without the radiobutton (just with the checkbox). The relevant part of code i'm using is as follows:
