Body
The page content of your document <a href="https://docs.google.com/file/d/0B4cQ-iOkdWKvM1RtaEJ3YjFrYkU/edit?usp=sharing" rel="nofollow">Mod 2.pdf</a> is utterly broken. It actually is broken so badly Adobe Preflight (from Acrobat 9.5.4) just like iText runs into an error while trying to analyze it. A manual inspection indicates that the most obvious errors relate to operations injected into an array of operands of TJ operations, e.g. <pre><code>[(OMB) 0.0 Tc -278.0 (Approval) 0.0 Tc -278.0 (2700-0042) ] TJ [(AMENDMENT) 0.0 Tc -278.0 (OF) 0.0 Tc -278.0 (SOLICITATION/MODIFICATION) 0.0 Tc -278.0 (OF) 0.0 Tc -278.0 (CONTRACT) ] TJ </code></pre> This pattern continues, i.e. every non-trivial [ ... ] TJ operation contains injected 0.0 Tc operations. This is wrong, cf. section 7.8.2 of the PDF specification <a href="http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf" rel="nofollow">ISO 32000-1:2008</a>: <blockquote> In PDF, all of the operands needed by an operator shall immediately precede that operator. Operators do not return results, and operands shall not be left over when an operator finishes execution. </blockquote> This makes <code>PdfContentStreamProcessor.ShowTextArray.Invoke</code> (responsible for processing TJ operations) run into the error. As the operand array of TJ may contain only strings and numbers, everything which is not a <code>PdfString,</code> is cast to <code>PdfNumber</code> but the Tc operators are instances of <code>PdfLiteral.</code>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
