    <p>I was trying to display a panel where user can see a list of items category(displayed as images) and on clicking they can view products within the category(images will be displayed)</p> <p>For displaying the item category, i used the ui:repeat nad the supporting bean calss Below is my xhtml code</p> <pre><code>&lt;ui:repeat id="repeat" value="#{getData.images}" var="img" varStatus="loop"&gt; &lt;h:panelGroup&gt; &lt;p:graphicImage id="img1" value="#{img}" alt="image not available" &gt; &lt;/p:graphicImage&gt; &lt;/h:panelGroup&gt; &lt;/ui:repeat&gt; </code></pre> <p>And the Managed Bean Code parts</p> <pre><code>private ByteArrayOutputStream baos = new ByteArrayOutputStream(); private List&lt;StreamedContent&gt; imageList = new ArrayList&lt;StreamedContent&gt;(); public List&lt;StreamedContent&gt; getImages(){ for (int i = 0; i &lt; sdh.getNumOfImages(); i++) { imageID = imageIDArray.get(i); ImageService imgSer = new ImageService(); imgList.add(imageID); imgSer.setData(imageID); baos = imgSer.getImage(); try { imageList.add(new DefaultStreamedContent(new ByteArrayInputStream(baos.toByteArray()))); } catch (Exception ex) { ex.printStackTrace(); } } imageNum = 0; return imageList; } public StreamedContent getData() { baos = imageList.get(imageNum); //imageList.add(baos); imageNum++; return new DefaultStreamedContent(new ByteArrayInputStream(baos.toByteArray())); } </code></pre> <p>Now my problem if i don't uncomment the 'imageList.add(baos)' in 'getData', the images are not displayed. Now i really wants to know how the 'ui:repeat' works, since the 'imageList' contains the images and i can save the same if required in either of the method. If i specify a fixed number (ex:'imageList.get(0)') in the 'getData' method then the same image is show multiple times. Where as if i put the 'imageNum' without the 'imageList.add(baos)' it throw error 'Error in streaming dynamic resource'</p> <p>I tired Bjorn Pollex's suggestion and made the necessary changes but now images don't appear</p>

    1. COYou are not referencing the loop-variable (`img` in your case) inside your `<ui:repeat>`. Your `getImages` should return a `List<StreamedContent>`, and your `<p:graphicImage>` should have `value="#{img}"`.

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.
