Session Variable Change Not Firing Event

[jimh]

Hi All,

I'm trying to fire an event when a session variable is changed, but nothing seems to happen.  I set up the variable and bound the changed event to a service, but when I update the session variable via a service, nothing happens.  I did confirm that the variable is being updated.  I'm using 8.5.3 and I found this:

Which is the same issue I appear to be having.  I was just wondering if anyone else has noticed the same issue -- as I'm probably doing something wrong. 

I'm trying to implement:

Option 1

Thanks!

This has somewhat been solved. I talked to a smart colleague who pointed me in a different direction. He suggested setting the variable via a mashup function and that seemed to do the trick!

Never could get the PTC example to work though.

Hi @jimh.

Glad you found a solution.  I will have someone look at the articles you referenced for needed updates.  They are both fairly old.

Hi @slangley 

There isn't a post as we chatted on the phone.  But, the gist of it is:

Instead of updating the session variable through the service, updated it through the actual mashup using a function.  So when I want to update the contained mashup, I also fire the mashup function that sends its output to the session variable via the function -- if that makes sense.

Hi @jimh.

I have marked one of your posts as the solution.  If you disagree with my choice, please let me know.

Regards.
