I have a xp:inputText element with property ultipleSeparator=","
The inputText has as databinding value="#{customerBean.customer.groupMail}"
The field for the customer object is defined as followed:
private List<String> groupMail = new ArrayList<String>();
When I enter multiple values and submit, the values are properly stored on the Notes document. But when I submit just a single value then I get a warning message:
java.lang.IllegalArgumentException: argument type mismatch
What am I doing wrong?
