Future implementations are intended to provide more * robust error handling throughout the framework (in the debug build only) * to check for common errors and problems. The messages issued by this class * will aid error checking. Error checks will be automatically removed in the * production build so that performance is not negatively impacted.
*Some sample messages currently implemented:
"DataProxy attempted to execute an API-action but found an undefined url / function. Please review your Proxy url/api-configuration." *"Could not locate your "root" property in your server response. Please review your JsonReader config to ensure the config-property "root" matches the property your server-response. See the JsonReader docs for additional assistance." **An example of the code used for generating error messages:
* @param {String} message */ Ext.Error = function(message) { // Try to read the message from Ext.Error.lang this.message = (this.lang[message]) ? this.lang[message] : message; }; Ext.Error.prototype = new Error(); Ext.apply(Ext.Error.prototype, { // protected. Extensions place their error-strings here. lang: {}, name: 'Ext.Error', /** * getName * @return {String} */ getName : function() { return this.name; }, /** * getMessage * @return {String} */ getMessage : function() { return this.message; }, /** * toJson * @return {String} */ toJson : function() { return Ext.encode(this); } });try { generateError({ foo: 'bar' }); } catch (e) { console.error(e); } function generateError(data) { throw new Ext.Error('foo-error', data); } *
