    Default DirectProxy example needed

    DirectProxy example needed


    I have searched the internet up and down to find an ExtJs DirectProxy example. Even one for 3.x would be great.

    I need explanation for instance, how to code the directFn function and what directFn.directCfg.method is.

    I got a directFn working, but what are the parameters that I get? One seems to be callback function. What parameters does this need?

    There is severe lack of documentation about this, I guess.

    Thanks!

    Thanks for the pointer. I had searched in examples, but did not find it, because I only searched for "DirectProxy" instead of "type: 'direct'".

    In those examples, what is that "TestAction"? I cannot find it declared anywhere.

    did you looked in examples/direct? Everything is in, TestAction is the direct method in php.

    Thanks. Got it. I had only looked in the .js files.

    I am no php expert. TestAction seems like a server side class that can be remotely called by js, I guess.

    But what about directFn.directCfg.method? Or even directCfg? I can't find that in the examples.

    It's an internal thing, you shouldn't touch it.

    OK, but I get an exception from ExtJs Beta 1 at line 38490 of ext-all-debug.js:

    Code:
    method = fn.directCfg.method;
    fn.directCfg is undefined.

    Code:
        var getData = function() {
          console.info('DirectProxy callback!');
          console.info(arguments);
        }
        var bufferStore = new Ext.data.BufferStore({
            id: 'bufferStore',
            pageSize: 200,
            model: 'Artikel',
            remoteSort: true,
            proxy: {
                type: 'direct',
                directFn: getData,
                model: 'Artikel'
            }
        });
    
    [...]
    
        bufferStore.guaranteeRange(0, 199);

    Because you haven't set it up properly. The directFn isn't a regular function, have a look through the examples.

    Hmm, I don't see this special setup. Any more pointers would be greatly appreciated.

    OK, I finally found this page, which explains some things:
    http://www.sencha.com/blog/ext-js-30...-for-everyone/

    However, this page (Direct specs) does not exist (anymore):
    http://www.sencha.com/products/extjs/direct.php

    I am beginning to understand what ExtJs Direct is and I think now, that this does not fit our needs, because we already have a remoting solution: DWR

    So, the question is: How can I get a callback from a Ext.data.BufferStore, when it needs data, so that I can call an existing DWR method to fetch the data?
