Stateflow chart coverage not 100% when only state entry action is executed

I have a model, where I have added an entry action (en: x=0;) in a state say A and used the same as condition ( [x==0]) to exit the state A. In this case, as soon the state A is entered, the entry condition is executed and immediately, the state A is exited because of the condition. In this case, coverage results show that the state A is not executed. When I change the action in state A from en: to du:, then coverage results show that state is executed.
Does it mean that, all states have to be active for alteast two timesteps?
Thanks in advance.

Not sure exactly what you're asking, but perhaps you could use a dummy variable:
if x == 0
dummy = 1;
end
while dummy == 1
execute commands that update x here
if x == 0
dummy = 0;
end
end
Can also use the "break" command instead of the "dummy=0" line if you want to exit the loop immediately.
