We detected that when we create Variables in formulas and then changed the value, this value is not updated in the formulas (keeps the first value and the variable must be removed and re-create).
For example, create text-type Variable "var" with value "a". Then change the value to "b", but the value being used is still "a".
Raul - This works if the user edits the Variable value in the Sidebar device, but there seems to be an issue if the change is made using the Edit dialogue...we are investigating
This is not a bug, but default behaviour. Text variable can take unlimited number of values, and you can edit these easily on the sidebar. What you tried to do is to edit the initial value, the value that will first appear when the variable is created. This initial value cannot be edited. Having said that, you can force the refresh (refresh button on the sidebar, next to your variable) and the new value will appear.
