Apache digester addSetProperty method is unclear and probably wrong.
--------------------------------------------------------------------
Key: DIGESTER-142
URL: https://issues.apache.org/jira/browse/DIGESTER-142
Project: Commons Digester
Issue Type: Bug
Affects Versions: 2.1
Environment: linux, 64 bits
Reporter: i30817
Priority: Minor
The addSetProperty method call:
Digester d = new Digester();
d.push(this);
d.addObjectCreate("rdf:RDF/pgterms:etext", Book.class);
d.addSetProperty("rdf:RDF/pgterms:etext", "rdf:ID", "setId");
OR
d.addSetProperty("rdf:RDF/pgterms:etext", "rdf:ID", "id");
on a class Book with the method public void setId(String)
running on this xml (simplified and not tested the simplification):
<rdf:RDF>
<pgterms:etext rdf:ID="etext10452">
<dc:publisher>&pg;</dc:publisher>
<dc:title rdf:parseType="Literal">Peter's Mother</dc:title>
<dc:creator rdf:parseType="Literal">De La Pasture, Henry, Mrs.,
1866-1945</dc:creator>
<pgterms:friendlytitle rdf:parseType="Literal">Peter's Mother by Mrs. Henry
De La Pasture</pgterms:friendlytitle>
<dc:language><dcterms:ISO639-2><rdf:value>en</rdf:value></dcterms:ISO639-2></dc:language>
<dc:created><dcterms:W3CDTF><rdf:value>2003-12-01</rdf:value></dcterms:W3CDTF></dc:created>
<dc:rights rdf:resource="&lic;" />
</pgterms:etext>
</rdf:RDF>
gives this exception:

...(my code the rest).
To work around it use instead:
d.addSetProperties("rdf:RDF/pgterms:etext", "rdf:ID", "id");
Doesn't make much sense to me. Also the confusion between a javadoc bean
property and a xml one is very, very misleading on the javadoc.
