Issues with Sapui5 V2 oData Model

HI All,

i am using the version of WEB IDE  "160225"  in that it using V2 oDatamodel ,

In that i am trying to use GorupId for submitChanges,

if i am just created an entry with following code

oModel.createEntry("/productsSet",{properties: { Pid:"54545", Description:"MDV"},groupId:"group123"})

it is directly sending an Batch request to backend without calling SubmitChanges();

i not aware about this V2 oDatamodel and also not found any examples.

i am planning to submit a group of changes and expecting some response as well.

can anyone help me out.

Thanks
