    Default Build error: "failed to find meta class definition for name reader.null"

    Build error: "failed to find meta class definition for name reader.null"


    REQUIRED INFORMATION


    Ext version tested:
    • Sencha Touch 2.1rc2

    Browser versions tested against:
    • N/A

    DOCTYPE tested against:
    • N/A

    Description:
    • I have a custom proxy, which uses a custom reader. In my store, I use this custom proxy, and configure some values for the custom reader. This was working before 2.1rc1. But now, it fails unless I add a "type: 'myreader'" to the store's "reader" config. That seems a little redundant, since myproxy already defaults to using myreader.

    Steps to reproduce the problem:
    • Create an app that uses the code below, and run "sencha app build production"

    The result that was expected:
    • Builds successfully

    The result that occurs instead:
    Code:
    [INFO ]		Compiling app.js and dependencies
    [INFO ]		Processing classPath entry : /project/sencha-compile-temp-dir
    [INFO ]		Processing classPath entry : /project/touch/src
    [INFO ]		Processing classPath entry : /project/app.js
    [INFO ]		Processing classPath entry : /project/MyAppDir
    [INFO ]		Processing classPath entry : /project/lib
    [WARN ]		[ [1000] : Yui Compressor Warning <> Trailing comma is not legal in an ECMA-262 object initializer => }, function() { ] :: ( /project/touch/src/app/Controller.js => 625 : 1 )
    [ERROR]		def was null
    [ERROR]		failed to find meta class definition for name reader.null
    [ERROR]		Exception running app build : JavaException: com.sencha.exceptions.BasicException: null
    [ERROR]		javax.script.ScriptException: sun.org.mozilla.javascript.internal.JavaScriptException: [object Error] (<Unknown source>#709) in <Unknown source> at line number 709
    Test Case:

    Code:
    Ext.define('MyProxy', {
    	extend: 'Ext.data.proxy.Ajax',
    	requires: ['MyReader'],
    	alias: 'proxy.myproxy',
    	config: {
    		reader: {
    			type: 'myreader'
    		}
    	}
    });
    
    Ext.define('MyStore', {
    	extend: 'Ext.data.Store',
    	requires: ['MyProxy'],
    	config: {
    		proxy: {
    			type: 'myproxy',
    			reader: {
    				rootProperty: 'myRoot'
    			}
    		}
    	}
    });


    HELPFUL INFORMATION


    Screenshot or Video:
    • N/A

    See this URL for live test case: N/A


    Debugging already done:
    • none

    Possible fix:
    • It works if you add "type: 'myreader'" to the reader config.

    Additional CSS used:
    • only default ext-all.css

    Operating System:
    • Mac OS 10.8.1

    This is due to the reader config from the store overwriting the reader config on the proxy. This wouldn't be hard to merge the two but the downside is we would have to do this on all configs which could break code (code expectations) and also cause perf issues.

    I don't have a strong preference either way....just thought I'd report it, since I'm pretty sure it used to work on ST 2.0.

    I've run into the same error and merging reader configs isn't the solution -- proxy.defaultReaderType and defaultWriterType aren't being honored even when they aren't overridden.

    Also, this error about unknown meta class definition should cite the class/file where it's encountered if possible
