I've got the same problem. With some images, Acrobat failed to display pages with this message: <blockquote> Insufficient data for an image </blockquote> My problem came from the colorModel in some jpeg images. To track which images weren't ok, i log the BufferedImage colorModel by <code>log.warn(img.getColorModel());</code> <pre><code>[VisualLocatorServlet.doGet:142] ColorModel: #pixelBits = 24 numComponents = 3 color space = java.awt.color.ICC_ColorSpace@4b7fce transparency = 1 has alpha = false isAlphaPre = false [VisualLocatorServlet.doGet:142] ColorModel: #pixelBits = 24 numComponents = 3 color space = java.awt.color.ICC_ColorSpace@4b7fce transparency = 1 has alpha = false isAlphaPre = false [VisualLocatorServlet.doGet:142] ColorModel: #pixelBits = 8 numComponents = 1 color space = java.awt.color.ICC_ColorSpace@19ef899 transparency = 1 has alpha = false isAlphaPre = false </code></pre> Obviously, failing images are 8-bits encoded. To fix that, i did the following: <pre><code>byte[] buffer = null; ByteArrayOutputStream out = new ByteArrayOutputStream(); BufferedImage img = ImageIO.read(new URL(visual)); /* resample 8-bits to 24-bits if necessary to fix pdf corruption */ if(img.getColorModel().getNumColorComponents()==1){ log.warn("components #1"+img.getColorModel()); BufferedImage out = new BufferedImage(w, h, BufferedImage.TYPE_3BYTE_BGR); Graphics2D g2 = out.createGraphics(); g2.setBackground(Color.WHITE); g2.drawImage(i, 0, 0, null); g2.dispose(); log.warn("redrawn image "+img.getColorModel()); } ImageIO.write(img, "jpeg", out); ... </code></pre> The main point is to recreate a BufferedImage in 24bits. (<code>BufferedImage.TYPE_3BYTE_BGR</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.
