I have a bit of an issue that’s causing size and maxArrayElements on all checkboxes selected after the first checkbox to be undefined if the input boxes are untouched. They are all set to default to 1 if not touched.
So in the sandbox, pick a dataschema, selectorField, check one box, just choose the lengthType, and hit submit. The object will come back (in the console) with the default values for size and arrayElements of 1.
Now if I check another box, just choose the lengthType, and hit submit, the size and arrayElements values come back undefined if not touched. They should default to 1. I do have a placeholder value set to 1, so it might be misleading. Specifically, the value prop on the inputs value={this.state.size[lastCheckedFieldName] || 1} handle this by setting the default value to 1 if not changed. But for some reason this isn't happening
This sandbox is reproducing the issue.
