com.vaadin.copilot.exception.CopilotException

com.vaadin.copilot.exception.MixedLanguageNotSupportedException

All Implemented Interfaces:

CopilotErrorCode, Serializable

public class MixedLanguageNotSupportedException
extends CopilotException
implements CopilotErrorCode

Thrown when a single operation would have to rewrite files in more than one language at once.

The common cases are safe and stay supported, because an operation resolves to the files holding the selected component's own create and attach locations: a Kotlin view under a Java @Layout, or a Java custom component used inside a Kotlin view. Only a component created in one language and attached in another is refused, since operations like move, wrap and extract rewrite both files and would need a coordinated two-language transaction.

The message names the files, because "created here, attached there" is the part the user needs in order to understand the refusal.
