/Errata:/ In my previous email I included an outdated XML node
description. My apologies. It should be:
<node name="a1icia_datanode"
factory="com.hulles.a1icia.cayenne.A1iciaDataSourceFactory"
parameters="hint"
schema-update-strategy="org.apache.cayenne.access.dbsync.SkipSchemaUpdateStrategy">
<map-ref name="a1icia_datamap"/>
</node>
The parameters value comes from the modeler DataNode form, and the form
field is "Location hint" in the "Custom Configuration" section.
/That/ is really what fixed the "empty parameters" message in the modeler.
