zero field value not shown in subpanel

[johnfd]

Hi all,

I have module Parent that displays a subpanel of a module Child in its DetailView form (they have one-to-many rel). The Child module has a field declared as follows:

 'min_allowed' => array(
            'name' => 'min_allowed',
            'vname' => 'LBL_MIN_ALLOWED',
            'type' => 'float',
            'dbtype' => 'double',
            'required' => true,
            'default' => 0,
            'comment' => 'minimum allowed evaluation value',
            'isnull' => false,
            'validation' => array ('type' => 'range', 'min' => '0', 'max' => '10')
        ) 
  

which it is displayed in subpanel. When this field is zero, it is displayed as empty under the field's column in subpanel. It is displayed correctly in Child's DetailView though. Any thoughts of what might be wrong?

Thank you,
John
