You need to pass child_args to the elines that contain child_args
themselves.
I'm not 100% sure because of the GrowingTableFieldSet, but it's either
directly a dict, or a list with a dict with one entry per row.
So either this
entryform.display(child_args=dict(...,
elines=dict(child_args=dict(etype=dict(...)))
)
or this:
entryform.display(child_args=dict(...,
elines=[dict(child_args=dict(etype=dict(...)), ...])
)
I presume the latter.
