I don't see what the problem is. Components call getters all the time.
Normally this is no problem since there should not be logic in the getter.
But your solution is not uncommon.
So, the model.isEmpty protects the loadData to be called multiple times. Two
things:
1 Are you sure you update your model attribute within loadData()? If not,
it's no surprise loadData gets called, since it remains empty. :)
2 When loadData loads an empty model, model.isEmpty() will always return
true, even if called multiple times.
I think the easiest thing to do (if what I'm describing is really your
problem) is replacing the isEmpty check with a "model == null" check, which
is more reliable, because it can deal with empty models. Also, it is more
fail-fast, instead of lurking in your code until the stars line up.
But a getter being called multiple times within a single request is not
uncommon. If you want to do stuff inside the getter, just protect the code
with a check like the null check I said before.
Hope this helps.
