extjs - ActiveItemChange and Dataview.Dataview display -

-

here subview enter image description here

i reworking ui. @ first button real button in titlebar. logic of button worked , mvced. have linked tab send proper signal controller. controller receive , navigate threw tree structure correctly.

the problem dataview.dataview in project tab not displaying after tap on button.

here code 

onsubviewactiveitemchange: function(container, value, oldvalue, eopts) { var me = container; switch(value.getitemid()) {     case  'back_innertab':         me.fireevent('goback');         break;     case  'exit_innertab':         me.fireevent('exit');         break;     case  'project_innertab':         me.fireevent('reloadchildren')         break;     case  'chart_innertab' :         me.fireevent('categorydisplay',me.getcomponent('chart_innertab').getcomponent('pie'));         break; }

}

with code, when tab tapped, controller job has intented, , tabpanel send me tab. if go project tab, display right elements. nice don't want need 2nd tap go project tab. here code 

  onsubviewactiveitemchange: function(container, value, oldvalue, eopts) {     var me = container;     switch(value.getitemid())     {         case  'back_innertab':             me.fireevent('goback');             me.setactiveitem(oldvalue);             break;         case  'exit_innertab':             me.fireevent('exit');             break;         case  'project_innertab':             me.fireevent('reloadchildren')             break;         case  'chart_innertab' :             me.fireevent('categorydisplay',me.getcomponent('chart_innertab').getcomponent('pie'));             break;     } }

normally send me active tab before tap, not. send me back tab project tab overlayed...

here inspector... (inspecting grey area in screenshot, after tab tap) enter image description here

how can correct in project tab , have displayed properly? need , can't seem find way of doing :s

onactiveitemchange

if change tab inside of event cause tab change, result undefined back-end implementation of not able support such task correctly.
