I think you would get the same result with a regular field. If the value is a scalar value (e.g. string, number) the result of a Javascript expression, there's no data context to work on.

 

 

 

Using ExpressionLanguage, you might get a rendered field, bit there's little to work with, as the field isn't bound to a data context. 

 

If you bind it to a scoped variable, or a document field, you will get an input[type=hidden]. 

 

E.g. 

 <xp:inputHidden id="inputHidden1" value="#{viewScope.hiddenField}" />   

 <xp:inputHidden id="inputHidden1" value="#{document.first_name}" />     

 

 

Ups. Yes a regular field also renders to a <span>. But at least the tag contains the value: <span .....>hallo</span>. Still this doesn't help ;)

So the value property is in reality a value binding...

 

Hi,

 

you can set the field value to compute on load.

F.e.
