dynamically generated fieldset is appended outside the form

[simonspitz]

Hi everybody. I've encountered some weird behavior of the form/fieldset classes.

I try to append a new fieldset to a previously rendered form.

This is the dynamically generated form:




MYFORM = function(){

var myForm;

return {

init : function(){

this.myForm = new Ext.form.Form({
labelAlign: 'left',
labelWidth: 200,
method: 'post',
url: '[some url]'
});

<?php foreach ($this->production_data as $key => $val): ?>

var fieldset = new Ext.form.FieldSet(
{legend:'Title: <?php echo $this->escape($val['title']); ?>'}
);

this.myForm.start(fieldset);

this.myForm.add(
new Ext.form.TextField({
fieldLabel: 'Title',
name: 'title_<?php echo $this->escape($val['id']); ?>',
width: 160,
value: '<?php echo $this->escape($val['title']); ?>'
})
);

this.myForm.end();

<?php endforeach; ?>

this.myForm.render('myForm');

} // END init
};

}();

Ext.EventManager.onDocumentReady(MYFORM.init, MYFORM, true);


in another class in this script I have a button to append a new fieldset to the form:



var button = new Ext.Button('button_new', {
text: 'Append fieldset',
handler: function(){

var fs = new Ext.form.FieldSet({
autoCreate: true,
clear: true,
labelAlign: 'left',
legend: 'foo label'
});

var form = MYFORM.myForm;

form.start(fs);

form.add(
new Ext.form.TextField({
fieldLabel: 'Title',
name: 'title_new',
width: 160,
value: '...'
}));

form.end();
form.render('myForm');
}
});


So far so good, but unfortunately the new fieldset is appended outside the form...

Even experimenting with getting the last generated dom element with


this.lastFieldSet = fieldset.getId();

in the MYFORM class and then trying to append


Ext.DomHelper.insertAfter(MYFORM.lastFieldSet, { tag: 'div', id: 'new_fieldset'});
....
fs.render('new_fieldset');

in the button function didn't have influence on the behavior.

It would be cool to know if this is a bug.

Cheers and big thanks

I don't think what you're doing will work. See this thread (http://extjs.com/forum/showthread.php?t=8070) for another way.
