Tree view doesn't work with properties containing object

[obenjiro]

Data

[{ id: 1, a: { id: 3, val: 1 }}, { id: 2, b: [{ id: 4, val: 1 }]}]

View

{
    view: 'tree',
    children: 'a or b',
    item: [
        'text:id', 'struct'
    ],
    expanded: 100
}

Actual Result

Expected To see object with id 3 in tree

Workaround that I have found. At least for now

{
    view: 'tree',
    data: '',
    children: '$r: (a or b) + []; $r.[size() > 1]',
    item: [
        'text:id', 'struct'
    ],
    expanded: 100
}

One more workaround (a or b or []) + []

A solution from 2024: a or b | is array ?:? [$] (or the full form: a or b | is array ? $ : ($ ? [$] : undefined)) More solutions:

• a or b | is object ? [$] : $ or a or b | is not object ?: [$]
• [...a or b].[] (creates temporary array)
• a or b |? [...] or full form a or b | $ ? [...$] : $ (creates temporary array)

Thanks, I think that will be enough for now.
