If I create an instance of a class in a view like this: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/2/22c276abdcef2b9b106a438459b78ad81e00faeb.png) That class is given a place in memory i.e. `< __builtin__.test instance at 0x8>` ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/6/b60df49be9a0cbfa7ad9299f1610bdf41ac04ca5.png) If I know that memory address, is there any way that I can recall the instance of `test` on the second button in this page? I don’t know if Java would allow me to do this or Python, but it would be convenient for a few use cases. ---

I guess another way to ask this question based off the problem, Is there any way for me to instantiate the class in button one, and reference it in button two. I know that I could make it serializable, store it as an object in a custom property, and then de-serialize it in the second buttons script. However sometimes you just can’t make thing serializable, so I am trying to see if I can get around that. ---

`system.util.getGlobals` maybe? ---

I think what that line means is that your globals map won't be emptied every time your scripting restarts from e.g. saving a project. Not that it will be persisted and accessible again if your gateway restarts. The contents of the map do not need to be serializable. ---

If that’s not actually the case then I have no idea why the documentation team wrote that. ---

Just tested it with a publish and my example still works!
