Brian,
One thing that I don't understand is why you see a different behaviour if
the condition is fulfilled (i.e. there is no StaleElementReferenceException)
and when it is not. Is it the case that the value of the date field does
not change when your test passes? The fact that you are getting the
exception stems most probably from the fact that the DOM is still updating
while the condition is being checked.
A slightly better way of avoiding the exception would be to wrap the
extraction of the element value in a waitFor:
waitFor { labRequest[0].dateField.value() } == requestDate
This way you will utilise the fact that waitFor() retries if there is an
exception thrown from the closure passed to it.
Anyhow you should probably use a better wait for condition to wait for the
page to stabilise after performing the action that triggers DOM updates.
The one you shared previously, that is waitFor { labRequest[0].labNameField.
value() }, clearly did not work given the behaviour you observed after
introducing it.
