Hi everyone,

I'm having a hard time dealing with an error that appeared overnight
in one of my PHP script:

Fatal error: Undefined class constant 'self::TYPE_HIDDEN' in
/#########/classes/framework/HTML/HTMLForm.php on line 120

HTMLForm.php snippet:

..........
// Creates the HTMLFormFields
foreach ($this->Record->Columns as $_column)
{
// Add only visible columns
if ($_column->IsVisible)
{
// Default field type
$_type=HTMLFormField::ELEMENT_TYPE_TEXT ;

// Adjust default type based on Column type
switch ($_column->Type)
{
case Column::TYPE_AUTONUMBER:
$_type=HTMLFormField::ELEMENT_TYPE_HIDDEN ;
break;

case Column::TYPE_BOOLEAN :
$_type=HTMLFormField::ELEMENT_TYPE_CHECKBOX ;
break;
default:
break;
117: }
118:
119: // Add the column to the list of fields
120: $this->Fields[$_column->Name]=new
121: HTMLFormField($this->Name,$_column,$_type);
122:
123: }

}

As you can see there is no refference to any TYPE_HIDDEN constant
at line 120, nor in the HTMLFormField's constructor.

I searched the net, but I just can't find the reason of this.
Can someone please me ?

Thanks,
Puiu
