extjs4 - Extjs 4 portlet on load collapsed not working properly

Question

I am using ExtJS portal code in my application

I want to make portlet in collapsed state at the time of loading the page. So I have done something like

items: [{
                            id: 'portlet-1',
                            title: 'Grid Portlet Texsds',
                            tools: this.getTools(),
                            height:200,
                            **collapsed:true,**
                            autoScroll :true,
                            items: Ext.create('Ext.app.GridPortlet'),
                            listeners: {
                                'close': Ext.bind(this.onPortletClose, this),
                                'endDrag': Ext.bind(this.onPortletDrag, this),
                                'resize' :Ext.bind(this.onPortletResize, this)
                            }
                        }

I have made collapsed property to true. But because of this when I am trying to expand the portlet [after page load] I can see blank Grid.Plz. refer the attached image.

What is the problem ? do I need to do refresh or something ? because when I set collapsed to false I can see the grid.

Please suggest what is missing here.

This is a code for the getTools: function(){

{
            type: 'Minimize',
            handler: function(e,target,panelHeader,tool){
                //panelHeader.ownerCt.toggleCollapse();
                if (panelHeader.ownerCt.collapsed)
                {
                    panelHeader.ownerCt.expand();

                }
                else {
                    panelHeader.ownerCt.collapse();
                }
            }
        }

for the first time when the portlet get load it is in collapsed state, Now when I click on cross icon not [the "^" for expand icons ] I can see the Blank grid.

Hope this time I am able to explain well.

我采用 Ext JS 4 示例门户应用程序并将您的代码（不带星号）添加到 portlet-1。它在加载时正确折叠并展开以显示网格。

我认为您发布的代码没有任何问题。也许您更改了周围容器的布局或布局属性，这会影响您的 portlet。

这是我完整的portal.js：

Ext.define('Ext.app.Portal', {

    extend: 'Ext.container.Viewport',
    //requires: [ 'Ext.diag.layout.ContextItem', 'Ext.diag.layout.Context' ],
    uses: ['Ext.app.PortalPanel', 'Ext.app.PortalColumn', 'Ext.app.GridPortlet', 'Ext.app.ChartPortlet'],

    getTools: function(){
        return [{
            xtype: 'tool',
            type: 'gear',
            handler: function(e, target, panelHeader, tool){
                var portlet = panelHeader.ownerCt;
                portlet.setLoading('Loading...');
                Ext.defer(function() {
                    portlet.setLoading(false);
                }, 2000);
            }
        }];
    },

    initComponent: function(){
        var content = '<div class="portlet-content">'+Ext.example.shortBogusMarkup+'</div>';

        Ext.apply(this, {
            id: 'app-viewport',
            layout: {
                type: 'border',
                padding: '0 5 5 5' // pad the layout from the window edges
            },
            items: [{
                id: 'app-header',
                xtype: 'box',
                region: 'north',
                height: 40,
                html: 'Ext Portal'
            },{
                xtype: 'container',
                region: 'center',
                layout: 'border',
                items: [{
                    id: 'app-options',
                    title: 'Options',
                    region: 'west',
                    animCollapse: true,
                    width: 200,
                    minWidth: 150,
                    maxWidth: 400,
                    split: true,
                    collapsible: true,
                    layout:{
