Hey All,
If you get an error as below when your do any CRUD operations using oDATA ,
Open your console and execute the below code & check if your app works (don't refresh after executing this code in console) https://gist.github.com/arv/9529994
if (!Document.prototype.createAttributeNS) { Document.prototype.createAttributeNS = function(namespaceURI, qualifiedName) { var dummy = this.createElement('dummy'); dummy.setAttributeNS(namespaceURI, qualifiedName, ''); var attr = dummy.attributes[0]; dummy.removeAttributeNode(attr); return attr; };
}
if (!Element.prototype.setAttributeNodeNS) { Element.prototype.setAttributeNodeNS = Element.prototype.setAttributeNode;
}
If your app works like a charm 
, then the reason for the above error is just because Chrome has remove some DOM Level 2 API's. Internally data.js uses two functions
document.createAttributeNS() , document.setAttributeNS()
which have been removed from chrome's API. The workaround code would manually add those functions to the DOM object document.
So, till this is fixed you can create a new js file say, workaround.js and copy the code posted above and import it to your ui5 app index.html as
<script src="workaround.js"></script>
Once this issue is resolved, you can remove the workaround script This is just one of the workaround available.
