B4J Question Loading Custom Type From KeyValueStore From Second App

[cklester]

I have an app which creates a KeyValueStore with one of the key-values a list of custom types.

Shouldn't I be able to use that same KVS and load the custom types in a second app?

I can't seem to make it work.

I'm including the same type definition in the second app, but receiving this error when trying to load it back:

Waiting for debugger to connect...
Program started.
Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.
Error occurred on line: 25 (KeyValueStore)
java.lang.RuntimeException: java.lang.ClassNotFoundException: b4j.example.coinapi$_symbol

I've tried putting the custom type def in "Main" and "B4XMainPage," but neither works.

Can I not load a custom type from a KVS from a second app?

ADDED: Yes, I searched. None of the solutions worked for me.

You can.

I've tried putting the custom type def in "Main" and "B4XMainPage," but neither works.

Make sure to do it in both apps.

I checked on this. In app 1, the custom type definition is actually in a class module that is neither Main nor B4XMainPage.

When I move it from the class module to Main, it now gives me the same error as I'm getting from app 2.

I have a 21MB KeyValueStore with this data. Am I going to have to rebuild that database if I want to be able to use it from app 2?

I thought custom Type()s were global regardless of where defined. Seem I was wrong. Do they have to be defined in Main or B4XMainPage?

- The CustomTYPEs must be in main when you write them to the kvs.
- The CustomTYPEs must be in main in your 2nd App when you want to read the KVS.
I fear you have to rebuild the kvs.
