Is there any way that i can store the state of this parameter in expression. I dont have anything to bind it from my mashup. So in the screenshot you can see that i have bool which has default value true and i just want it to change every time i use this function. For example I change the state to false then again next time i evaluate i turn it into true.

Hi @RadekIOT  @Rocko , Thank you both of you. Its working now. The problem was that when i uncomment the console.log it does not work... I just commented it out and now everything is working perfectly fine! 🙂 Sometimes Thingworx is a bit different haha..

To store and reuse the computed value, you can try

a) a Checkbox you make invisible

b) a Mashup parameter

c) a Session variable

    I have created a mashup parameter named status. Its a checkbox and i have selected it with true and i change it everytime i run this expression so i change it to true and false

    Maybe try to assign a value when opening the mashup first to debug. You can also log something on the event of statusChanged which should be there on the mashup.

    It can be it does not work with mashup parameters.  Options a) and c) are sure shots though.
