Could not apply filter TableFilter error

Hi,

I have a form with a Text field as TYPE_AHEAD asociated with a valuelist gerentes. That valuelist uses related values using a global variable to select only users that are managers. The list appears into the field but this error is shown into the log (some times 5 times one after the other):

Could not apply filter TableFilter{lookupValuelist.nameFilter}(hrdb,usuarios) [valuelist_name=gerentes] on table usuarios : column not found:valuelist_name

I am running Servoy 6.0.10
