Custom Control with multiple aggregation doesn't render anything

Hi all,

I am working on creating a custom control. The control accepts an aggregation called "documents" with cardinality 0..n.

var TagTab = Control.extend("sap.ui.demo.DocTab", { metadata: { library: "sap.m", properties: { expandable : {type : "boolean", group : "Misc", defaultValue : true}, expanded : {type : "boolean", group : "Misc", defaultValue : true} }, defaultAggregation: "documents", aggregations: { documents: {type: "sap.m.IconTabFilter", multiple: true, singularName: "item"} } } });

Now I am using this control in XML view like this:

<DocTab items="{/docs}">

<m:IconTabFilter text="{docName}" ></m:IconTabFilter>


But nothing gets rendered on the screen. I tried checking the binding in render function of the control using : console.log(oControl.getDocuments()) but this returns null.

What else do we need to implement in order to get the multiple aggregation working ? Currently I don't have anything apart from control metadata and render fucntion.

have you tested the UI control with hardcoded data?, if not then test that once...

Yes, it works fine with the hard-coded data. Its just when I introduce binding .. it stops working

I have checked the same binding with a stanadrd control and works fine there.


show UI control code..especially render.js
