Sorry, I didn't notice you were using t:selectItems in the first part
of the message.
Here's the issue:
myBean.loggedDropDownActions.entrySet
would be resolved as
myBean.getLoggedDropDownActions().getEntrySet()
and not as
myBean.getLoggedDropDownActions().entrySet()
So your value list would be null/empty.
Not sure about clay, but facelets would allow you to define a static
function where you could get the entry set value....
#{myFunctions:entrySet(myBean.loggedDropDownActions)}
I suppose you could just define
public Map.Entry getLoggedDropDownActionsEntrySet()

Mike,
Thanks. I guess I'll go for the t:selectItems then. But that doesn't explain
why t:selectItems produces an empty t:selectOneMenu. Do you have any idea
why?
Thanks,
Joost Schouten

You need to use t:selectItems.
f: does not support var or value (at least, it's not supposed to).
