Ext.Window.show() keeps the old parameter value when re-opens the window

Question

I have a Ext.Window which is called inside a function. I pass a parameter to window through function. When I try to re-open window with a new value, window performs operations with the old value.

Here is my code -

var Win;
LoadWindow = function (id) {
if (!Win) {
    Win = new Ext.Window({
        id: 'Pop-win',
        layout: 'fit',
        width: 650,
        modal: true,
        height: 450,
        closeAction: 'close',
        plain: true,
        items: [Panel],
        listeners: {
            close: function (w) {
               Win.removeAll();
            },
            show: function (p) {
                Store.reload({
                    params: {
                        'ID': id
                    }
                });
            }
        }
    });
}
Win.show();
}

PS: I Use extjs 3.4 version

Move the Store.reload(); part out of the show listener. The id it refers to is always referring to the first time you create the window.

If this window is not being used too often, it might suffice to simply change it to use closeAction: 'destroy' so that you generate a new window each time. If you need to reuse it, write a helper function on the window that reloads the store separately, and call Win.customStoreReload() followed by Win.show(). By the way, closeAction: 'close' is also not a valid closeAction. The config can only be set to either 'destroy' or 'hide'.

LoadWindow = function (id) {
    if (!Win) {
        Win = new Ext.Window({
            id: 'Pop-win',
            layout: 'fit',
            width: 650,
            modal: true,
            height: 450,
            closeAction: 'hide', // either 'hide' or 'destroy'. 'close' is not a valid option
            plain: true,
            items: [Panel],
            listeners: {
                close: function (w) {
                    Win.removeAll();
                }
            }
        });
    }
    Store.reload({params: { 'ID': id }});
    Win.show();
}
