Hidden form field

[mhaddy]

If a form field is hidden

{
  xtype:'hidden',
   name:'UserID'
}

an exception is thrown:
maxLength is not defined

at

function f1(out,values,parent,xindex,xcount) {

 try { with(values) {

  return(maxLength !== undefined)

 }} catch(e) {}

}

When do you get the error? Just displaying is fine for me:

Ext.create('Ext.form.Panel', {
    renderTo : Ext.getBody(),
    width    : 400,
    height   : 400,
    title    : 'Test',
    items    : [
        {
            xtype : 'hidden',  //should use the more standard hiddenfield
            name  : 'text'
        }
    ]
});

Interesting. Your panel worked for me also. It seems to fail when wrapped in a window:

var dlPassChangeWin = Ext.create('Ext.window.Window', {

    width: 400,

    height: 400,

    title: 'Test',

    items: [

        {
            xtype: 'hidden',  //should use the more standard hiddenfield
             name: 'text'

        }

    ]

});

dlPassChangeWin.show();

And you are using 4.1 beta 1? I'm not getting any error using that code.

[mhaddy]

Uhhg. I am. Unfortunately, all my forms are contained in windows and all that have hidden fields are throwing this error. I will try to isolate this outside my application.

[mhaddy]

I have no problem getting this exception outside my application using the code above.

Let me ask you this...
The error is wrapped in a try/catch block. The settings I am using is to break on all exceptions (caught or not).

Are you breaking only on uncaught exceptions or are you just not getting it at all?

It's a caught exception when testing the definedness of an optional value. Not a bug.

[mhaddy]

Throwing an exception to test the definedness of an optional value sounds crazy to me - but I guess that is a topic better discussed elseware.

Thanks for the info.
