[dbforms] NPE with empty table and db:dataLabel

[Christian Kullmann]

First of all my long overdue thanks for a brilliant tool.
 
I am migrating an application from V1.1.13 to V2.2.
 
I have a problem when using this new version with empty tables.I have a set of JSP's 
that are supposed to render a read-only view of tables. I then use radioselection and 
gotobuttons to navigate to edit panels and other updating functions.
 
The problem seems to occur whenever I use the db:dataLabel tag. I need this in order 
to imbed either db:query or db:staticdata tags to resolve field values. 
 
The problem appears as 
 
javax.servlet.ServletException: Error: null
at 
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:463)
...
 
I see the exact same symptom when using the bookstore sample 
testBOOKSListAutoUpdate.jsp changed as shown below
 
   <db:body allowNew="true">
    <tr>

     <td><db:dataLabel fieldName="BOOK_ID"/></a>&nbsp;</td>    <!-- Changed to cause 
NPE -->

     <td><db:textField fieldName="ISBN"/>&nbsp;</td>
     <td><db:textField fieldName="AUTHOR_ID"/>&nbsp;</td>
     <td><db:textField fieldName="TITLE"/>&nbsp;</td>
    </tr>
   </db:body>
