Hi Henner,
I don't understand this piece of code:
DbBodyTag::doStartTag, line ~207 ------------------------------------------------------------------
if (!rsv.isLast()) { rsv.moveNext(); // teleport us to future...
// This must be done because currentRow_xxx is reread from
// the pagecontext after(!) the body of the tag. This means
// that the current body contains the currentRow of rsv(i - 1)
// # jp 27-06-2001: replacing "." by "_", so that SCHEMATA can be used
pageContext.setAttribute("currentRow_"
+ myParent.getTableName().replace('.', '_'),
rsv.getCurrentRowAsMap());
try {
pageContext.setAttribute("position_"
+ myParent.getTableName().replace('.',
'_'),
Util.encode(myParent.getTable().getPositionString(rsv),
pageContext.getRequest().getCharacterEncoding()));
} catch (Exception e) {
throw new JspException(e.getMessage());
}
rsv.movePrevious(); // ...and back to present ;=) }
}
------------------------------------------------------------------
why rsv.moveNext() ? Is it like the jdbc resultSet, where it is necessary to do a resultSet.next() to get the first record ?
I'm testing this stuff with an application; I commented the rsv.moveNext() and rsv.movePrevious() lines ... it seems the application works without problems AND I can access to the currentRow_${TABLENAME} page attribute getting the correct values: the following "jsp" declarations on the current record give all the same correct result:
<db:label fieldName="IS_ONLINE"/>
${currentRow_ITEM.IS_ONLINE} // jstl syntax permitted only in Tomcat 5.x and web apps 2.4
[scriplet: <%=currentRow_ITEM.get("IS_ONLINE") %>]
Am I missing something (insert, update and delete operations seem to work correctly...) ?
My env is: DbForms latest from CVS with default navigation settings, jdk1.5, tomcat 5.5.7
Regards, Luca

I debugged it yesterday - only change is to move the currentRow to the body tag.
