    Table in PDF footer is rendered in header

    Chris Sweeney Newbie

      When I try and include a table (because the footer I need is two lines of text) the footer is rendered behind an image that I have in the header. Anyone have any success with more complex footers? Example



      <f:facet name="header">
                <font size="14" family="garamond">
                <header borderWidth="0" >
                 <ui:include src="../components/Header.xhtml"/>
              </header>
         
                
              <footer borderWidthTop="1" borderWidthBottom="0" alignment="center">
              <table columns="1" horizontalAlignment="center">
                <f:facet name="defaultCell">
                      <cell  horizontalAlignment="center" borderWidth="0"/>
                      </f:facet>
                <cell horizontalAlignment="center"><paragraph><font size="7" horizontalAlignment="center">Contact information:</font></paragraph></cell>
                      <cell horizontalAlignment="center"><paragraph><font size="7" horizontalAlignment="center">Line 2:</font></paragraph></cell>
                </table>
              </footer>
               </font>
      </f:facet>

          Can you open a JIRA issue for this?  I definitely see that this is a problem.

            I wanted to have in my footer the report date on the left and page x on the right.  I also tried a table at first but I had the same problem you did.  I found that just using space characters rendered line spacing in the pdf (scroll all the way to the right to see what I mean!):



            <f:facet name="header">                     
            <font size="8">            
            <footer borderWidthTop="0" borderWidthBottom="0" alignment="center">#{dateTimeDisplay.dateDisplay}                                                                                                                                                                                                                                                  Page: <pageNumber /></footer>                
            </font>
            </f:facet>



            If your footer text width might vary widely this might not work for you.  I feel comfortable with it in my scenario since the text widths will remain pretty much the same.

              hi,


              i also have the same problem. The footer is get out just under the header.
              I try to get a table in the footer but have no success with it.
              I saw in the forum some ideas to use html table. But it does not work in the footer.


              Since this thread is one year old i would hope there should be a workaroud or a fix


              If it was implemented already may be there are some ideas how it could  be implemented??


              any tips would be very nice


              thanks and regards
              Dmitri

                hi,


                i have built my own solution for this problem. May be someone find it usefull...
                First i have implemented a TAG:




                public class UIDirectFooter extends ITextComponent
                {
                     /**
                      * @return the footerContent
                      */
                     public Iterator<Element> getFooterContent()
                     {
                          return footerContent.iterator();
                     }
                
                     protected List<Element> footerContent = null;
                
                     /** {@inheritDoc} */
                     @Override
                     public void createITextObject(FacesContext context) throws IOException, DocumentException
                     {
                          System.out.println("UIDirectFooter createITextObject() called");
                          footerContent = new ArrayList<Element>();
                     }
                
                     /** {@inheritDoc} */
                     @Override
                     public Object getITextObject()
                     {
                          System.out.println("UIDirectFooter getITextObject() called");
                          return null;
                     }
                
                     /** {@inheritDoc} */
                     @Override
                     public void handleAdd(Object other)
                     {
                          System.out.println("UIDirectFooter handleAdd() called");
                          if (other instanceof Element)
                          {
                               Element element = (Element) other;
                               System.out.println("try to add " + element.getClass().getName());
                               footerContent.add(element);
                          }
                          else
                          {
                               throw new IllegalArgumentException("cannot add " + other);
                          }
                
                     }
                
                     /** {@inheritDoc} */
                     @Override
                     public void removeITextObject()
                     {
                          System.out.println("UIDirectFooter removeITextObject() called");
                     }
                     
                     
                }
                


                Then i have a seam component derived from UIDocument. The footer drawing is made in it.
