virtual form and validator (bug or feature)
I got 2 virtual forms
First, VF is associated with a drop down.
Second, VF is associated with text field and a button.
The text field has a validator
Upon selecting a value from dropdown (VF1 get submitted) the text field will get populated.
Here is where it get strange, the validator get called and when first form get submitted (dorpdown change) and the validator will not get called if the second VF get submitted.
How can I reverse the order? Have the validator evoked when the right virtual form is submitted?

I tried to duplicate your problem but it seems impossible.
Message Group Component.
DropDown List in Virtual Form 1: Participates and Submits. Auto-Submit is on.
Text Field in Virtual Form 2: Participates
Button in Virtual Form 2: Submits
Prerender Code:
public void prerender() {
if (dropDown1.getSelected()!= null) {
textField1.setText(dropDown1.getSelected());
}
}
Text Field Validate Code:
public void textField1_validate(FacesContext context, UIComponent component, Object value) {
error("validator called");
}
I see that the is not getting updated when I choose a new value from the drop down list., because it does not participate in the form submit for the drop down list (VF1). Also, the I see that the validator method is not getting called (makes sense).
Then, I make the text field participate in both VF1 and VF2 and, because of the call to error() from the validation method, I see that the validator is indeed being called when I click the button to submit VF2 as well as when I choose it from the drop down list.
I cannot reproduce your problem. Can you help?

Ok it's a bug in the way SJSC update 1 handle validator
I have removed all the Virtual Forms, commented out all the validator procedures and made sure that in the properties there are no validator for the drop down. I also added in the prerender()
info("VALS: ");
Validator val[] = dropDown1.getValidators();
for (int i = 0; i < val.length; i++) {
info(val[i].toString());
}
When I ran it I got nothing.
I then created an
public void TEMP_validate(
FacesContext context, UIComponent component, Object value) {
}
and placed the procedure in the drop down validate property. To my surprise I found that the system is trying to find the old validator that I commented out when I change the value for the drop down.
