Collapsed ContainerPanel doesn't expand

[pdantuluri]

Hi,

I am having some issues with the Container Panel. If I collapse the panel by calling collapse method, it doesn't expand when I made the call expand. ContainerPanel.isExpanded() method returns false. So what is wrong? If Container Panel is collapsed, it can't be expanded programatically? Manually clicking the button expands the panel, though.

Any help would be appreciated.

Thanks

did you try it in a newer version of GXT not in the GXT 1.x ( i assume that you using 1.x because you post in the 1.x category)

Sorry for posting it in GXT 1.x help. Actually I am using GXT 2.0.1 version. Still I see the issue of not expanding the ContentPanel after calling expand method.

on my system a small example works.

so it should do this.
can you make a standalone example with is one class with EntryPoint - so everyone can replay your problem.

my example:

package com.mycompany.myapplication.client.forumsnippets;

import com.extjs.gxt.ui.client.event.ButtonEvent;
import com.extjs.gxt.ui.client.event.SelectionListener;
import com.extjs.gxt.ui.client.widget.ContentPanel;
import com.extjs.gxt.ui.client.widget.Html;
import com.extjs.gxt.ui.client.widget.Window;
import com.extjs.gxt.ui.client.widget.button.Button;
import com.extjs.gxt.ui.client.widget.form.FormPanel;
import com.google.gwt.core.client.EntryPoint;

        private void createWindow() {
            setWidth(400);

                    setCollapsible(true);
                    add(new Html("abc"));
                }

            add(contentPanel);
            add(new FormPanel() {

                        @Override

                            contentPanel.collapse();
                        }
                    }));
                    add(new Button("B", new SelectionListener<ButtonEvent>() {

                            contentPanel.expand();
                        }
                    }));
                }
            });

        }
    }
