   2 robust error handling throughout the framework (<b>in the debug build only</b>)
   3 to check for common errors and problems. The messages issued by this class
   4 will aid error checking. Error checks will be automatically removed in the
   5 production build so that performance is not negatively impacted.</p>
   6 <p>Some sample messages currently implemented:</p><pre>
   7 "DataProxy attempted to execute an API-action but found an undefined
   8 url / function. Please review your Proxy url/api-configuration."
   9 </pre><pre>
  10 "Could not locate your "root" property in your server response.
  11 Please review your JsonReader config to ensure the config-property
  12 "root" matches the property your server-response.  See the JsonReader
  13 docs for additional assistance."
  14 </pre>
  15 <p>An example of the code used for generating error messages:</p><pre><code>try {
  16     generateError({
  17         foo: <em>'bar'</em>
  18     });
  19 }
  20 catch (e) {
  21     console.error(e);
  22 }
  23 <b>function</b> generateError(data) {
  24     throw <b>new</b> Ext.Error(<em>'foo-error'</em>, data);
