It wouldn't get loaded from there, unfortunately, unless you included it
somehow. application.dryml is the typical place that such things go.
There is one important gotcha to note, however, between a param tag and a
regular tag. For instance, this:
<def tag="form" for="SomeModel">
<form merge>
<field-list fields="foo, bar, baz />
</form>
</def>
will produce a form with fields foo, bar and baz but without a submit button,
whereas this:
<def tag="form" for="SomeModel">
<form merge>
<field-list: fields="foo, bar, baz />
</form>
</def>
will produce a form with fields foo, bar, and baz *and* the default submit
button. Note the : after field-list.
In the first case, you're replacing the entire content of the form tag with
what you're passing. In the latter, you're passing the field-list parameter to
form leaving the remainder of the contents unchanged.
