OPENUI5 ODATAv4 FunctionImport绑定无法正常工作

Question

Currently, I have set up OPENUI5 to use a ODataV4 data source. This source includes a functionImport on a Collection without parameters. In the XML View, I have defined

<Title text="{/Orders/OrderService.MyFancyFunction()}"/>

In the network trace I can see the function being called correctly:

Request:

GET Orders/OrderService.MyFancyFunction() HTTP/1.1

Response:

{"@odata.context":"http://localhost:50156/odata/$metadata#Edm.String","value":"Happy Hippo"}

However, the string is not shown on screen; inspecting the element through the UI5 inspector shows "text" being an empty string, but also having a correct binding to the function shown above.

Any ideas?

Thanks, regards

这似乎是OPENUI5中当前ODataV4实现中的一个错误：当函数不使用命名空间时，它很有效。
