@sencha/extjs/no-deprecated-method-override

Report the overriding of a deprecated method

Rule Details

This rule will report when a deprecated method is being overridden.

In this example, we are overriding the validate method of the Ext.data.Model Class, which was deprecated in 5.0 and the doComponentLayout method of the Ext.Component Class, which was deprecated in 4.1. So upgrading from a prior version to a version greater than 5.0 will cause this problem to be reported.
