I use a parameter in an action expression. Sometimes I'd like to pass null
as argument.
<tr:commandLink text="Clear Filter" immediate="true" action="#{documentView.setFilterId(null)}">
The action handler method is
public void setFilterId(Long id) {
This more or less works, however when passing null
in EL the java side received 0 (zero).
Not a big deal, but quite unexpected and makes the java code a little uglier.
Is it a bug?
