Hi, i'm looking the method getValue() of UISelectItems:
public Object getValue()
{
if (_value != null) return _value;
ValueBinding vb = getValueBinding("value");
return vb != null ? vb.getValue(getFacesContext()) : null;
}
And I see that if a value property of the SelectItemsTag is setted with
a ValueBinding format, then every time I get getValue() the value is
rebuilded. This could be a problem for example in the case I have a
property value of my managed bead used for value binding that access to
DB to return the result, because in the life cycle of a page, this
getValue() is called more than one time. My question is:
Why the getValueBinding("value") result is not cached? For example:
private Object _vb=null;
private boolean vbCalculated=false;
public Object getValue()
{
if (_value != null) return _value;
if(!vbCalculated) {
ValueBinding moment = getValueBinding("value");
_vb= moment.getValue(getFacesContext());
vbCalculated=true;
}
return _vb;
}
Ciao
Mario
