bindelement method does not send out OData service request

Hi,

There is a weird behavior in our application that sapui5 does not make OData service request (I use Chrome to monitor network activity)

as we try to bindelement with a particular entity.

We are able to make OData service request against NW Gateway to retrieve a collection.

(create ODataModel instance and make it global by using sap.ui.getCore().setModel(myODataInsance)

and then a sap.m.List calls bindAggregation method with /Courses path to get Courses collection)

Everything seems fine. However as we try to calll bindElement and do something like this

oControl.bindElement(

"/Courses('123456')/") It seems looking into OData model in the memory (no request is out) The problem is

the collection does not have course detail information.

I hadcode the course id with a random number and then I can see the request is out. (but of course it will return 400 since the course id does not

exist).

The temporary solution in our side is to create a new ODataModel (so. no calling collection first) and then oControl to bind element.

However I think they are using the same service so it does not make much sense to use two ODataModel instance. Any thought we may

do something wrong?
