The task is to show a specific plan depending on a certain object value.

Code:

$(function(){
 if (typeof grp != 'undefined') {
   grp.listen('1/1/1', function(object, state) {
     var value = object.value;
     if (state == 'value') {
       if (value == 1) {
         showPlan(11);
       }
       else if (value == 2) {
         showPlan(12);
       }
       else if (value == 3) {
         showPlan(13);
       }
     }
   });
 }
});

Hi admin, I have some problems with this script.
I use boolen object, I changed value == 1 to value == true/false.
When I'm changing value from false to true, my visu page is switching.
But  when I Send True once again nothing happens. to make it works I nedd to switch my object to false and then to true.
whats the reason of this behavour? (tested on 20170620 FW)

the second thing I need is the opposite task. I need to write some value to object when specific plan is Opened. could you help me?
