Question

Personal Environment

Hi,

I am doing one of the GuidedTours. Yesterday my environment was upgraded to version 10.

Today I get the following error while publishing one of the labs. I do not know if there is a connection between these events,

The error log provides no further clues, unfortunately. Does anyone have an idea what to do?

Internal Error

Invalid compiler output.

Hi Dimitri,

If you refresh the module references it will publish ok.

I'll alert the team responsible for the tutorial to update the module so it doesn't have this problem.

Thanks!

Hi Dimitri,

From the stack trace I can only see that it has something to do with the references of that module.

Which lab were you publishing? Can you post the oml in this thread for me to try it out?

Hi Carlos,

Thank you for you reply. I have attached the OML.

This is the start of Lab 22 (Scaffolding and RichWidgets). Because of the error I used the Quickstart-version of the lab (attached here), but I still got the same error.

OSMDb_Core.oml

I am having the same issue - but don't know what you mean by "reference the module references." For me the error is occurring back in the Style Sheets section of the tutorial. Thanks!

[UPDATE- I worked it out. On the Development tab you need to click Add Dependencies then Refresh All in the dialog that appears]
