Quick transform h:selectOneMenu to q:dropDownField?

Hi

 

What is the best method of transform of this case?

 

h:selectOneMenu  value=Integer

  f:selectItems value=List of javax.faces.model.SelectItem(Integer,String,String)

 

to

 

q:dropDownField   value=Integer converter=()

  q:dropDownItems  value=List of javax.faces.model.SelectItem(Integer,String,String)

 

For now q:dropDownItems do not support List of SelectItem's so I use converter Integer<>SelectItem but usage of  objectToString is very intensive and not neccesery.

 

Is any better method?

Krashan,

 

Actually, the purpose of the DropDownField component is a different from the SelectOneMenu. The SelectOneMenu component is a select component, the user can only select one of the predefined values. The DropDownField component is an input component where the user can either type in a value or select one of the values from an attached drop-down list. The user can type not only the value from the predefined list, but any value.

 

We are going to add new component that will be extended SelectOneMenu (ComboBox) component in one of the future releases.

 

Regarding your question. Yes, you are right. Since the DropDownField component is an input component, not a select component, you have to use a converter. There is no any other ways to use the DropDownField component with SelectItems.

 

Regards,

Tatyana
