1901	problems with event handling	ekofman@…	Willi Braun	"Today, I updated Open Modelica to rev 13538 (I had last updated about six months ago). I found that Event Handling is not working properly. Almost any model with discontinuities gets stuck after the first state event is detected. 
Consider for instance model Modelica.Electrical.Analog.Examples.CharacteristicIdealDiodes

In previous versions of OpenModelica state events were not correctly detected (I think OM only searched for events at output instants, so accurate event detection was strongly dependent on the output interval), but the simulations did not get stuck.

Now, once a state event is detected, OM keeps detecting it forever. 

I think this is a serious bug (now OM is not able to simulate discontinuous systems) but I assume it can be easily fixed.
