We are using extjs 3.4. The purpose is to replace a component in a Ext.Window. Even if there is no error when we remove the old and add the new component, when trying doLayout() the error Uncaught TypeError: Cannot read property 'offsetWidth' of undefined occurs.
The code that creates the window is:
function createWindowConf(id, winconf, items) {
var conf = {
id: id,
title: winconf.title,
iconCls: winconf.icon,
x : winconf.xpos,
y : winconf.ypos,
width : parseInt(winconf.xsize),
height : parseInt(winconf.ysize),
layout : winconf.layout, //'border',
border : false,
resizable : winconf.resizable,
manager: windows,
shadow: false,
closable: true,
items: items
};
var win = new Ext.Window(conf);
win.render(desktopEl);
return win;
};
The items are a Ext.grid.GridPanel and a Ext.form.FormPanel. According to user's current selection in grip (component in position 0) the old form should be removed and a new should be added (component in position 1).
The code that creates the form is:
var theConfig = {
id: config.yid,
bodyStyle: 'padding:5px 5px 0',
width: 370,
maxWidth: 370,//not resizable
minWidth: 370,
layout: 'form',
margins: '0 0 0',
region: 'east',
split: true,
colapsible : true,
trackResetOnLoad: true,
autoScroll: true,
fieldDefaults: {
msgTarget: 'side',
labelWidth: 75
},
items: [],
buttons: [scopeDetails.updateButton, scopeDetails.submitButton]
};
this.detailsForm = new Ext.form.FormPanel(theConfig);
and the items added afterwards.
The code that updates (adds/removes) components from the window is:
this.updateWin = function(moduleForRemoveId, form, idWin) {
var win = this.getWindow(idWin);
if (win != null) {
win.remove(moduleForRemoveId);
win.add(form);
win.doLayout();
}
}
and produces the error in win.doLayout().
By removing all components and add the add the new ones:
win.removeAll();
win.add(this.grid);
win.add(this.form);
win.doLayout();
we have the same error.
Any suggestion will be really helpful since more than 3 days spent for that error
