EL: Warnings on write-only value bindings

Is there anything I can do to make Idea not show a warning for the "to" attribute value here?

<tr:setActionListener from="#{options.employeeId}" to="#{reportAction.employeeId}"/>

The reportAction bean only has a setter, which is all that is needed.
Probably Idea can't really figure out that the value is only ever written to by the tag, but can't I configure that somewhere?
