Store locding problem with buffered: true,

[zjda]

Hi All,

I am trying to make it more restful by dynamically setting proxy url. This is my store code:

    buffered: true,
    leadingBufferZone: 4,
    pageSize: 2,
    proxy: {
        setGroupId: function(id) {this.url = '../rest/admin/group/' + id + '/user'},        
        type: 'ajax',
        url: '../rest/admin/group/0/user',
        reader: {
            type: 'json',
            root: 'user',
            totalProperty: 'total',
            successProperty: 'success'
        },
    },
    remoteSort: true,
    simpleSortMode: true,
    sorters: [{
        property: 'name',
        direction: 'ASC'
    }],
    autoLoad: false,
    groupId:0,
    load4Group: function(id) {
        if (id != this.groupId) {
            this.removeAll(true),
            this.groupId = id;
            this.proxy.setGroupId(id);
            this.pageMap.clear();
               this.load({
                   scope: this,
                   callback: function(records, operation, success) {
                       console.log(records);
                   }
               });
        }
    }

First time when calling load4Group(), it works fine. The value of "total" is 2 and it sends only one request to the server for page 1. However, afterward it will send 3 requests to the server to get pages 1, 2 and 3 even though the "total" value is 2 in these responses. The loading mask will never go way. I try to use removeAll and pageMap.clear to rest the buffer, but it does not help. If I set "buffered: false", the problem will NOT occur.

Any suggestion will be appreciated.

The following code fixes the problem:

    load4Group: function(id) {
        if (id != this.groupId) {
            this.groupId = id;
            this.proxy.setGroupId(id);
            this.removeAll();
            if (this.prefetchData) {
                this.prefetchData.clear(); 
                delete this.guaranteedStart;
                delete this.guaranteedEnd;
                delete this.totalCount;
            }
            this.guaranteeRange(0, this.pageSize - 1); 
        }
    }
