18 * @class Ext.Error
19 * @extends Error
20 * <p>A base error class. Future implementations are intended to provide more
21 * robust error handling throughout the framework (<b>in the debug build only</b>)
22 * to check for common errors and problems. The messages issued by this class
23 * will aid error checking. Error checks will be automatically removed in the
24 * production build so that performance is not negatively impacted.</p>
25 * <p>Some sample messages currently implemented:</p><pre>
26"DataProxy attempted to execute an API-action but found an undefined
27url / function. Please review your Proxy url/api-configuration."
28 * </pre><pre>
29"Could not locate your "root" property in your server response.
30Please review your JsonReader config to ensure the config-property
31"root" matches the property your server-response.  See the JsonReader
32docs for additional assistance."
33 * </pre>
34 * <p>An example of the code used for generating error messages:</p><pre><code>
35try {
36    generateError({
37        foo: 'bar'
38    });
39}
40catch (e) {
41    console.error(e);
42}
43function generateError(data) {
44    throw new Ext.Error('foo-error', data);
45}
46 * </code></pre>
47 * @param {String} message
