OMI-changevalue-simulation time (Tn) jumping forward/backward when changing value

[isiho]

OMI Interactive – changevalue
I'm testing the OpenModelica Interactive with the TwoTanks example and the example client and with my own client. If I use the command
" changevalue#seq#Tn#par1=0.03#end",
The following problem occurs:
e.g: If I change the value at Tn = 50,
in the next result message from OMI to GUI Tn will jump to Tn=70 and
in the next step the simulation time will either return to Tn = 50
or sometimes it also returns to a time < 50 ( e.g. Tn=35). Then the simulation continues.
For my purpose OMI should change the value at the time I tell him and it should continue at that time. The simulation time shouldn't jump forward or backward, because if the simulation continues with the new value at the wrong time the results will be false.
I attached 2 screen shoots.

OMI hasn't been part of OpenModelica for some time, so this is no longer relevant.
