Advanced problem does not work.

[kwangkim]

I am trying add an Advanced problem with boxes.

https://inginious.readthedocs.io/en/v0.5/teacher_doc/task_file.html#advanced-code-problem

But it does not seem to work properly. I copied and pasted a sample code.

type: code
header: some text
name: And again, another name
boxes:
    boxId1:
        type: text
        content: Some additional text
    boxId2:
        type: input-text
        maxChars: 10
        optional: true
    boxId3:
        type: multiline
        maxChars: 1000
        lines: 8
        language: java

It only works as usual code problem, boxes do not work.

How can I fix this?

seems that boxes were removed https://github.com/UCL-INGI/INGInious/commit/6dbcbcda56ad3141e514156dbd37539d628b20f5

I am also interested in this feature -- is there a workaround (a plugin)?
