Hi Lia,
I figured it out how to do it correctly.
The item in the parent form has to be identical to the first item in the
child form.
For example, the red items in both forms have to be exactly the same in
terms of its schema name (dc), element (contributor), and qualifier
(editor). The child should be also named accordingly
(dc-contributor-editor).
The second item (green) in the child form can be any other schema you
prefer. The logic sounds werid but that is how I get it work.
<form name="publicationStepGroup"> (parent form)
<row>
<field>
<dc-schema>dc</dc-schema>
<dc-element>contributor</dc-element>
<dc-qualifier>editor</dc-qualifier>
<repeatable>false</repeatable>
<label>Editor</label>
<input-type>inline-group</input-type>
<hint>The editors of this publication.</hint>
<required>You must enter at least the author.</required>
</field>
</row>
</form>
<form name="publicationStepGroup-dc-contributor-editor"> (child form)
<row>
<field>
<dc-schema>dc</dc-schema>
<dc-element>contributor</dc-element>
<dc-qualifier>editor</dc-qualifier>
<label>Editor</label>
<input-type>onebox</input-type>
<repeatable>false</repeatable>
<required>You must enter at least the author.</required>
<hint>The editors of this publication.</hint>
</field>
<field>
<dc-schema>oairecerif</dc-schema>
<dc-element>editor</dc-element>
<dc-qualifier>affiliation</dc-qualifier>
<label>Affiliation</label>
<input-type>onebox</input-type>
<repeatable>false</repeatable>
<required />
<hint>Enter the affiliation of the editor as stated on the
publication.</hint>
</field>
</row>
</form>
Kind regards,
Gary
