Body
Having a little trouble here. Basic premise is that I need to hit a button, generate HTML, create PDF, and throw into output-stream for download: <pre><code><ice:commandButton title="Download" image="/images/dl.png" value="Download" action="#{bean.downloadPDF}"> </ice:commandButton> </code></pre> <hr> <pre><code>public void downloadPDF() throws IOException { PD4ML pdf = new PD4ML(); pdf.setPageSize(PD4Constants.LETTER); pdf.setPageInsets(new Insets(0, 0, 0, 0)); pdf.setHtmlWidth(1000); pdf.enableImgSplit(false); pdf.generateOutlines(false); File pdfFile = new File("tmp.pdf"); FileOutputStream fos = new FileOutputStream(pdfFile); StringReader sr = new StringReader("Testing Download"); pdf.render(sr, fos); FacesContext facesContext = FacesContext.getCurrentInstance(); PortletResponse portletResponse= (PortletResponse)facesContext.getExternalContext().getResponse(); ResourceResponse portletResourceResponse = (ResourceResponse) portletResponse; portletResourceResponse.setContentType("application/pdf"); OutputStream out = portletResourceResponse.getPortletOutputStream(); out.flush(); facesContext.responseComplete(); } </code></pre> Problem I am having is after the <code>pdf.render()</code>, when I attempt to generate the response based on the current context and the convertion to <code>ResourceResponse</code>: <pre><code>java.lang.ClassCastException: com.liferay.portlet.RenderResponseImpl cannot be cast to javax.portlet.ResourceResponse </code></pre> What is the proper way to take that file and output it in Liferay/portlet?

Guidance

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.
