Problem using SAX as described in xdksample_040602

Question

I am trying to implement SAX-based parsing/loading of large XML-documents into an Oracle817 database.
When trying to create the procedure "docExpand" I get an error on the following line of code:
"select xml into p_xml from xml_tbl where id=xmlid;"
This is because the XML column in table XML_TBL is of type CLOB, but the p_xml variable is defined as VARCHAR2(32767).
I then tried to change VARCHAR to CLOB in all the relevant places and succeded in creating all the procedures,
but when I try run the procedure "docExpand" as described in the script "DBTest.sql" I get a type mismatch error:
SQL> exec docExpand(1,1);
begin docExpand(1,1); end;
ERROR at line 1:
ORA-00932: inconsistent datatypes
ORA-06512: at "SAXSAMPLE.XMLDOCUMENTEXPANSION", line 0
ORA-06512: at "SAXSAMPLE.DOCEXPAND", line 16
ORA-06512: at line 1
It seems to me that the CLOB parameter of XMLDocumentExpansion is incompatible whith the java.lang.String parameter of ExDocumentHandler.docExpand ?
All I can think of now, is to change the CLOB in XML_TBL and DTD_TBL to VARCHAR2(32767), but then I wont be able to handle documents larger than 32K (for which I suppose DOM would appropriate).
Is there a way to make this work ?

Since the PDL documentation does not state that it will honor embedded converters I would assume it does not. Considering what you see that is most probably the case. If you think this is inconsistent put it in as an issue.
In the meanwhile you can use the following:
<f:viewParam .... converter="#{topTenHome.dateConverter}"/>
Where 'dateConverter' resolves to a DateConverter instance.
Hope this helps
