How to dynamically load an XML fragment in XML view?

Question

Suppose I have the following XML view:

    
        &l         


        

Answer 1

I think the only solution will be initialization of fragment from onInit method of controller:

sap.ui.controller("my.controller", {
    onInit : function(){
        var oLayout = this.getView().byId('mainLayout'), //don't forget to set id for a VerticalLayout
            oFragment = sap.ui.xmlfragment(this.fragmentName.bind(this));
        oLayout.addContent(oFragment);
    },

    fragmentName : function(){
       return "my.fragment";
    }
});

Answer 2

The fragment name can also result from a binding, including an expression binding which evaluates to a constant. As formatter functions return strings, and not booleans, === 'true' has been added in the following example:

Example: Dynamic Fragment Name

<core:Fragment fragmentName="{= ${path: 'facet>Target', formatter: 'sap.ui.model.odata.AnnotationHelper.isMultiple'} === 'true'
    ? 'sap.ui.core.sample.ViewTemplate.scenario.TableFacet'
    : 'sap.ui.core.sample.ViewTemplate.scenario.FormFacet' }" type="XML"/>
