Repeating Activity/Node selection multiple times!

[fsalemi]

Hello Felix,
I am using the activity selection functionality in my app multiple times.
For the moment, when an activity is selected (clicked), it generates a reactive message through JS callback function (input$process_activities) which I can use this in my shiny app. However if the user click on the same activity again for the second time this (input$process_activities) is not generated. Probably it is because this activity is already selected.
However I need to use this (input$process_activities) in my app even if the node is already selected.
I can modify the JS function to fulfill this purpose, if I know where to look for it. Can you please help directing me to the correct JS file which generates (input$process_activities), so that I can tailor it for my app?
Thanks in advance,
