Problem with gform_pre_render and a custom field type

Hi!

I created a custom field type and i try to change the defaultValue by using the gform_pre_render, but somehow its not working.

Here is the gform_pre_render function:

add_filter("gform_pre_render", "populate_field");
				function populate_field($form){
					$postID = $_GET['id'];
				    if($form["id"] != 5)
				       return $form;

				    foreach($form["fields"] as &$field) {
				        if($field["id"] == 34){
				            $field["defaultValue"] = 'just a test default value';
				        }
				    }
				    return $form;
				}

So as you can see, nothing special, however, its not working. If i set the default value in the admin panel, its working fine, but i can't change it like this. I also tried to change the description, and surprisingly that is working fine.

Any idea? Thanks

Well, not exactly i created it, but its definitely a custom made field, thats what i tried to explain somehow:) You can find it here:

By default, it doesn't support the defaultValue option, so i changed the code in line 124 from this:

wp_editor('', $input_id, $args);

To this:

wp_editor($field["defaultValue"], $input_id, $args);
