ComboBox items binding with template, throws exception.

Hello all, i encounter an problem when trying to bind items of to a ComboBox (https://sapui5.netweaver.ondemand.com/sdk/#docs/api/symbols/sap.ui.commons.ComboBox.html) component.

At the moment, the process of binding items on the ComboBox component it's done like follows:

var itemTemplate = new sap.ui.core.ListItem();                          //  creating a ListItem object

itemTemplate .bindProperty("text", ".........");                             //  bind for the "text" property a certain path from the model

var comboBox = new sap.ui.commons.ComboBox({});               // create the ComboBox

comboBox .bindItems("........",itemTemplate);                           // bind the items from a certain path, and provide as a template for the list items the                                                                                                     // previously created one

Everything works as expected, except the fact that the following exception it's logged:

"A shared template must be marked with templateShareable:true in the binding info -  "

While this seems suggestive, I still was not able to find when during binding should the "templateShareable" property set to "true". Did anyone else encountered this issue? Am I doing something wrong when binding the items of a combobox?

Thanks
