Portlets don't resize into different size columns inside Portal

**Neilcoder** · 21 Jun 2012, 3:38 AM

Required Information

Version(s) of Ext GWT
�Ext GWT 3.0 Release Candidate�

Browser versions and OS
(and desktop environment, if applicable)

�Chrome 17, Windows XP, Aston Shell�

Virtual Machine
No

Description
Portlets don't resize when moved to a different sized column inside portal. Pictures will explain this below. Portal is added inside of a TabPanel.

Run mode
development mode

Steps to reproduce the problem

</i>
Create a TabPanel
Add the PortalLayoutContainerExample from the examples, add it to a tab on the tab panel
e.g.: PortalLayoutContainerExample myPortal = new PortalLayoutContainerExample();
tabPanel.add(myPortal.asWidget(), new TabItemConfig("PortalLayoutContainerExample",true));
run this code and play around with moving the portlets

Expected result
portlets should resize to the different columns in the Portal

Actual result
portlets sometimes resize, sometimes don't

Test case

Code:

package com.example.demo.client;


import java.util.Iterator;

import com.example.demo.client.MainToolBar.StockProperties;
