How to Hide a customfield when other customfield has no value?

Question

Hi,

I'm using Behaviour plugin with this script associated to the customfield I want to hide:

FormField ci = getFieldByName("CI afectado")

if(ci.getValue() == ""){
 getFieldByName("Proyecto de gestión (PdG)").setHidden(false);
}
if(ci.getValue() != ""){
 getFieldByName("Proyecto de gestión (PdG)").setHidden(true);
}

In this case, the customfield "Proyecto de gestión (PdG)" is allways hidden.....

But...... if I use the next code:

FormField ci = getFieldByName("CI afectado")

if(ci.getValue() == null){
getFieldByName("Proyecto de gestión (PdG)").setHidden(false);
}
if(ci.getValue() != null){
getFieldByName("Proyecto de gestión (PdG)").setHidden(true);
}

In this other case, the customfield "Proyecto de gestión (PdG)" is allways shown.....

Where is my mistake?

Regards

Begoña

It looks like ci.getValue() returns null always.

That explains that both ci.getValue() != "" and ci.getValue() == null are evaluated to true.
