My application which was recently migrated to Ext JS 5.1.0 from 4.1.1 is showing a random issue,
on panel collapse/expand the layout fails. the issue ia random. might appear on the second expand /collapse. or the following ones.
It shows the following error in console:
Uncaught TypeError: Cannot read property 'getStyle' of null
Attaching screen shot of the error in console.
Attaching screenshots of the UI.
I have used border layout for viewport.
The problem panel is in the center region panel. This panel has a 'responsive' plugin which changes it to a collapsible panel in devices other than desktop.
Following is the code for the view.
Code:
Ext.define('XX.view.report.agency.CampaignReportPanel', { extend : 'Ext.panel.Panel',
border : false,
xtype : 'campaignreportpanel',
initComponent : function() {
var prevMonthDate = new Date();
prevMonthDate.setMonth(prevMonthDate.getMonth() - 1);
var accountStore = Ext.create('Ext.data.Store', {
model : 'XX.model.Account',
proxy : this.accountStoreProxy,
listeners : {
load : function() {
accountStore.insert(0, {
id : -1,
title : Ext.getStore('MessageResources').getMessage('CAMPAIGN_REPORT_ALL')
});
}
}
});
var cgTypes = XX.controller.CreativeGroup.prototype.getSupportedTypesObjectArray(false);
var channelTypeStore = Ext.create('Ext.data.Store', {
fields : ['id', 'displayField'],
data : cgTypes
});
var campaignStore = Ext.create('Ext.data.Store', {

}
}
});

goButton.fireEvent('click', goButton);
