Hi < kirillrakhman> If the screenshot is needed I can attach that also

kirillrakhman · Answer

Thank you the stack trace is enough I ve added it to the issue you linked

kirillrakhman · Answer

It seems the compiler throws an exception when trying to report gt Exported declaration uses non exportable 0 type 1 Does this help you to add a workaround to your code Also does K1 not report a similar error If not and you think the new error is inappropriate you should file an additional issue

Gopi S · Answer

Hi K1 did not have a similar error I have annotated the DoublyLinkedList class with JSExport IMO the inner class does not have to be marked with JSExport even If I do so I get this error JsExport is only allowed on files and top level declarations

Gopi S · Answer

I could not figure out the workaround

Sasha · Answer

I m afraid the only workaround is to move the inner class to the top level and pass the outer class as a parameter to the inner class
