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

[jweber]

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:

Test Case:

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'
			}
		}
	}
});

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.

[jweber]

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
