The docs for <collection> should probably be more explicit - it
expects that the context will be an array. So your example would
shorten to:
<collection with="&@all" />
As previously written, it was attempting to call the collection tag
once for each element in @all, which obviously didn't do what you
want. :)

Note that if you're attaching a multiline field to an attribute, you
may actually want to change the datatype; some DBs (MySQL, as an
example) limit :string types to pretty pathetically short lengths
(255, I believe). YMMV depending on your target DB.
In any case, if you just want to swap out one field's tag in a list,
you could do this (assume the field is called special_field):
<field-list fields="...">
<special-field-tag:>
<input for-type="text" />
</special-field-tag:>
</field-list>
This may need tweaking to match the surrounding context (field-list
may be a param, for instance) but it sounds like you've already got
that part figured out.

It does take a while - and the current state of the documentation for
the taglibs doesn't exactly help. In the meantime, we always try to
respond ASAP to questions, so ask away! :)
