How to set Items in ButtonViews

[gikotim]

Hi!
I try to set the items in a ButtonViews from a database.
I use the onLayout event for setting the items. I get the wait-cursor for a minute (timeout ?) and then the items are displayed.
It can not be a problem of the db, as the same happens when I remove all db-related code and just put in single code line for setting the items.
If I use the before/after-Append event the elements are shown immediate, but the same timeout happens when clicking on a button.

and, sorry to ask this for this element also: how to I set the id & caption from the rsp.data?
My data look like: [["1", "Menu A"], ["2", "Menu B"], ["3", "Menu C"]]

        _bv_params_onLayout:function (profile) {             // setup menu //            SPA.request({action:'get_admin_parm_menu', key:"", value:""}, //                function(rsp){ //                    var items=[]; //                    _.each(rsp.data, function(v, k){ //                        items.push({"id":"m"+k, "caption":v[0]}); //                    }); //                    SPA.bv_params.setItems(items);                     SPA.bv_params.setItems([{"id":"m1", "caption":"item a"}, {"id":"m2", "caption":"item b"}, {"id":"m3", "caption":"item c"}])                 }             );         }

Thank you very much for all your support!

Why use onLayout event? It's UI layout event, not suitable for adding new items.
You should use Com's onReady or onRender to load data and set them to controls.
SPA.request({action:'get_admin_parm_menu', key:"", value:""},                 function(rsp){                     var items=[];                     _.arr.each(rsp.data, function(v){                         items.push({"id":v[0], "caption":v[1]});                     });                     SPA.bv_params.setItems(items);            } )
