Description

After running the following code, it is not possible to retrieve the function calls and function result messages so that they can be readded to the history.

InvocationContext invocationContext = new InvocationContext.Builder()
            .withToolCallBehavior(ToolCallBehavior.allowAllKernelFunctions(true))
            .build();
        List<ChatMessageContent<?>> results  = chat.getChatMessageContentsAsync(chatHistory, kernel, invocationContext)
        .block();

In .NET, after invoking the chat completion model, the ChatHistory is mutated so that it includes all of the messages that were created (including function calls from the assistant role and function results as tool messages)

Because of this limitation, it is not possible for the AI to reuse context it was able to retrieve in previous function calls/results. For example, in the following chat, the AI used a function call to get the states of the lightbulbs. This included the IDs of the lights which are necessary for subsequent function calls.

Unfortunately, because the function result is lost, subsequent questions aren't able to use that information and the AI cannot complete them.

Research direction

Start at the Java call to getChatMessageContentsAsync shown in the issue and trace how InvocationContext and ChatHistory handle function calls and results. Compare the described Java behavior with the .NET ChatHistory behavior; done means function-call and function-result messages can be retrieved or readded so later questions can reuse the retrieved context.
