Hi,

For what its worth I find myself doing the same thing on a component I am developing.

It would be nice if there was an api for this but it doesn't seem there is one.

I wonder how easy it would be to add...or if its planned?

My component allows for new fields to be defined by the end-user for any object that supports it within the component.

I accomplished this by subclassing JModelAdmin, and making all of my models inherit from my new base admin model.  Within this class, I override the 'preprocessForm' method that is called by the MVC framework and add the custom fields into the form.  It's working great, except I'm curious if there is a better way of doing it.

Here's a snippet from that method. This block of code is looping over all custom fields that are configured for the object.  What seems a bit kludgy is how I have to create an XML representation of the fields and then shove them into the form with the ->setField(..) call.  It seems that you should be able to use the JField objects and add them to the form.

                        // this defines how the field will be rendered.

                        $fieldType = 'inputbox';

                        $fieldOptions = '';

                        $fieldFormat = '';

                        switch ($field->typecode)

                        {

                                case 'BIT':

                                        $fieldType = 'radio';

                                        $fieldOptions = '<option value="0">JNO</option><option value="1">JYES</option>';

                                        break;

                                case 'TEXT':

                                        $fieldType = 'textarea';

                                        break;

                                case 'DATE':

                                        $fieldType = 'calendar';

                                        break;

                                case 'DATETIME':

                                        $fieldType = 'calendar';

                                        $fieldFormat = 'format="%Y-%m-%d %H:%M:%S"';

                                        break;

                        }

                        $xml = sprintf('<fieldset name="udf"><field type="%s" name="udfId%d" label="%s" description="%s" %s>%s</field></fieldset>'

                                        , $fieldType

                                        , $field->id

                                        , htmlspecialchars($field->code)

                                        , htmlspecialchars($field->description)

                                        , $fieldFormat

                                        , $fieldOptions);

                        // this assigns the stored UDF data into the data that is bound to the form

                        $data->{'udfId'.$field->id} = $field->data;

                        $xmlElement = new SimpleXMLElement($xml);

                        $form->setField($xmlElement);

K...
