ODataModel function metadataLoaded returns promise which doesn't react on the request response if failed

SAPUI5 1.38.18

this code doesn’t react on the XHR response:

	this.getModel().metadataLoaded().then(
				function(oSuccess) {
					// do nothing
				},
				function(oError) {
					
				});

I also tried catch - never worked.

Yes - I agree I can use metadataFailed event. However I don’t understand then why do we need this method if it returns the promise working only on a half.

Thank you!

This is by design, the metadataLoaded promise does never fail, as described in the API documentation: “The promise won’t get rejected in case the metadata loading failed but is only resolved if the metadata is loaded successfully.”.

This is done this way to enable the possibility to retry loading the metadata and have it resolved later on.
