Version incompatibility

Ignition
1

We have recently upgraded our version of Ignition to 7.2.7. When we deployed the system to our customer (who was still running 7.2.3) we found that they were getting a null pointer exception error for (we think) every table when opening a window. We couldn’t carry out too much testing as we had to fix the problem quickly, which we did by upgrading the customer to 7.2.7.

I wasn’t aware of anything that should stop this working - is there an incompatibility between these versions that would cause this error?

Are you saying you developed a project in 7.2.7, and then deployed it to a 7.2.3 gateway by importing the project (or gateway backup)?

If so, I’m pretty sure Ignition isn’t designed to do that. I don’t think any version of Ignition is forwards-compatible (i.e. 7.2.3 doesn’t work with projects created in 7.2.4+, or at least will likely have problems).
