Multi-Blind generation runs into No multiBLD number for round

[lgarron]

Actual (problem) behavior

When trying to generate Multi-Blind scrambles, TNoodle errors with:

No multiBLD number for round Round(id=333mbf-r1, format=3, scrambleSetCount=1, scrambleSets=[], extensions=[Extension(id=org.worldcubeassociation.tnoodle.SheetCopyCount, specUrl=, data={"numCopies":"1"})]) specified

Expected behavior

I can generate Multi-Blind scrambles.

Steps To Reproduce

1. Launch TNoodle and open http://localhost:2014/scramble (don't log in).
2. Add a multi-blind round to the default competition.
3. Click "Generate".

This results in the error above. Clicking "More" gives:

org.worldcubeassociation.tnoodle.server.webscrambles.exceptions.ScrambleMatchingException: No multiBLD number for round Round(id=333mbf-r1, format=3, scrambleSetCount=1, scrambleSets=[], extensions=[Extension(id=org.worldcubeassociation.tnoodle.SheetCopyCount, specUrl=, data={"numCopies":"1"})]) specified

I can seem to kick things into action by selecting the field for the number of scrambles and re-typing 35 to replace the existing value of 35. It seems a listener on the field needs to be triggered.

Desktop (please complete the following information):

• OS: macOS 14.2.1
• Browser: Chrome 120
• TNoodle Version 1.2.1
• Java version [e.g. Java 8] (how to find out)

I ran into the same error using Firefox 121.0.

A possible workaround is to increase then decrease the number of generated scrambles for multi, then it's possible to generate the scrambles.
