I found the "when" clause could not response some events in the software of simulationx.

Modelica Language
I do the modelica programme in the simulationX environment. Recently, I found in the some cases, the statement “when” could not response the many event. Here is one of my examples.
when v5>0 then reinit(xx5,0.03);elsewhen v5<0 then reinit(xx5,0.06);end when;
During the simulation process, the variety xx5 changing events from negative to positive or from positive to negative couldn’t trigger the command of “reinit”.
In the programme piece, there is a clause “x=x1+x5”. If I designate “x1=0”, the clause “when v5>0 then reinit…” works well. If the variety x1 is integrated in a complicated equation, the clause “when v5>0 then reinit…”does not work well completely. I could not understand the above problem. Is the problem a bug of the software. Does anybody could help me to solve the problem.
The piece of the my codes is as following
equation
x=ctr1.x-ctr2.x;
v=ctr1.v-ctr2.v;
x=x1+x5;
vv5=der(xx5);v5=der(x5);vv5=0;
when v5<0 then reinit(xx5,0.03);elsewhen v5>0 then reinit(xx5,0.06);end when;
vv1=der(xx1);v1=der(x1);vv1=0;
when v1<=0 then reinit(xx1,10);elsewhen v1>=0 then reinit(xx1,20);end when;
