    Default [CLOSED]Ext4 PR5: "Cannot create an instance of unrecognized alias: reader.tree"

    [CLOSED]Ext4 PR5: "Cannot create an instance of unrecognized alias: reader.tree"


    It looks like this example (which works with 'ext-4.0-pr4'):

    http://dev.sencha.com/deploy/ext-4.0...tree/tree.html

    does not work with 'ext-4.0-pr5'.

    The error message is (Firefox 4.0 and Chrome 12.0.712.0):

    [Ext.ClassManager] Cannot create an instance of unrecognized alias: reader.tree

    I have attached a reproduction test case of the issue: Same code side-by-side,with the only change being that in 'index-pr4.html', ExtJs 4 PR4 is used, and in the other, 'index-pr5.html', ExtJs PR5 is used.

    Forgot to include the 'json' config; now it's included in the attached 'lazy_tree.zip' file test case.

    Default Has 'Ext.data.TreeReader' been intentionally omitted in PR5?

    Has 'Ext.data.TreeReader' been intentionally omitted in PR5?


    If 'Ext.data.TreeReader' is defined in PR5 'ext-all-debug.js', the test case works for PR5.

    Checking for the existence of the missing alias, I noticed that in PR4, 'Ext.data.TreeReader' is defined, but not in 'ext-all-debug.js' for PR5.

    TreeReader has been removed as of Beta1. You should use the Json/Xml readers as per usual.
