ct has no properties

[elric6]

Hello, i make 2 forms with ext, and when i declare and render the second form, i see this error... 'ct has no properties'....


the code is :



var form = new Ext.form.Form({
labelAlign: 'right',
labelWidth: 50
});

form.render('"formulario"');

var formBusqueda = new Ext.form.Form({
labelAlign: 'right',
labelWidth: 50
});

formBusqueda.render('"formularioBusqueda"');


why??

thx in advance

This doesn't tell us much. You probably don't have a container built that you're trying to render into. Step thru the code w/Firebug to see what container (ct) it's looking for.

[brian.moeskau]

form.render('"formulario"');

It's because of your nested quotes -- you are telling it that the id of your element is actually "formulario" WITH the double-quotes as part of the id. Do this instead:


form.render('formulario');

Hi!

This error may also occur if you want to render a form, grid, etc. into a HTML container that doesn't exist. That means:

You want to render a form


form.render("myForm")but you forgot to create, for example a


<div id="myForm"></div>user23

Hey guys

I am new to Ext library and have 'ct has no properties' caught by firebug

I am using formgrid. JSON is used to pass data from server side to javascript file

The error seems to be in ext-all-debug.js

Complete citing is

ct has no properties
onRender(null, null)ext-all-debug.js (line 15681)
render("basic", undefined)ext-all-debug.js (line 12237)
render()ext-all-debug.js (line 13843)
Component(Object title=Basic StatusBar renderTo=basic width=350)ext-all-debug.js (line 12164)
apply()ext-base.js (line 9)
apply()ext-base.js (line 9)
apply()ext-base.js (line 9)
(no name)()statusbar-demo.js (line 47)
fire()ext-all-debug.js (line 1488)
fireDocReady()ext-all-debug.js (line 1525)

chrome://firebug/content/blank.gif this.el = ct.createChild({


The application works fine, its just that it has yellow exclamation at bottom left with error keyword

Please let me know if you think we can get rid of this

Thanks

I was getting the same error. In my case, I had the div, but by server side program generating the javascript was placing the render call outside the Ext.onReady() function.

Moving javascript inside Ext.onReady fixed the problem.

I know this is an old thread and the OP would have fixed the error, but posting here for the benefit of others who might be getting the same error.

From the stack trace it looks like it is erroring out when trying to render a StatusBar in the file statusbar-demo.js on line 47 to a div with an id of 'basic'.

Do you have a div with an id of basic in your page? If not make sure that you do. ct has no properties means that the ct (or container) did not exist.
