Handle error in grid from RestDataProvider

cascadian

Hi, the documentation says an exception is thrown if the REST response indicates failure.

A promise is returned in response to the success request status. In case of the failed request (response.status == 500), an exception with an error text is thrown.

How do I catch that error and how would I revert the row or cell to the previous value if, for example, an update/PATCH request failed.

Thanks!

Hello cascadian,

The RestDataProvider does not have a build-in error-catching system, and therefore while sending the request it is necessary to intercept the action that triggers this request and depending on the request result allow updating the data (return true) or prohibit it (return false).
