Exception retrieving IDO metadata etc.

Hi,

While running through the Hello World Tutorial step by step, I'm now getting this error message:

This occurs after having:

• Written the first form script at the beginning of Part 6.
• Created the CalcOrderTotal event
• Referred to it in the Data Change property of the Item and Count components, both on the form and its grid collection.

I need to click 3 times on the OK button for the modal to stop displaying. Then the Orders form (that I prefixed with MB1_, as seen on the screenshot) works as expected, immediately updating the Order Total field when updating the Item or Count fields.

Any idea to fix the error? Otherwise, how can I investigate its cause?

Thank you.

I found the issue. Somehow, an empty Secondary Collection had been added to the Collections list of the form:

I guess I clicked the [+] button, not realizing that I was on the Collections Tab and not the Event Handlers one.

I just had to delete this empty collection to fix the issue.

Apologies, please ignore my previous post.
