Behaviour that works on any (input) field

[Bernd Anderer]

I am not sure if I am missing something here...

What I want to do is this:

create a behaviour that limits the number of characters to 64.

If I want that behaviour to be active I just add the according field to the Fields list in the behaviour configuration.

Currently my code looks like this:

def field = getFieldByName("Document ID")
if ((field?.value as String)?.length() > 64) {
field.setError("Length of this field should be less than 64 chars")
} else {
field.clearError()
}

The problem is obvious - there is a hardcoded field name.

Question:

how can I make the script generic, so that it works on all fields that are added in the fields list?

Hi @Bernd Anderer, 

you can use this

def field = getFieldById(getFieldChanged())

getFieldChanged() refers to the field Id that the server side script is attached to

Thanks - this was what I was looking for.
