RenditionService node update error.

[docterwatson]

I am having some issues getting renditions to properly populate using the RenditionService. Here is what I am doing:

Creating about six renditions for an image using the renditionService, here is an example of how I am doing this.

NodeRef renderedNode = this.createRendition(node, <path to rendition folder + rendered node name>, <imageMagick command>, "myRendition");

private NodeRef createRendition(NodeRef node, String destination, String command, String rendDefName) {
      QName renditionName = QName.createQName(NAMESPACE_URI, rendDefName);
      RenditionDefinition renditionDef = renditionService.createRenditionDefinition(QName.createQName(NAMESPACE_URI, rendDefName), ImageRenderingEngine.NAME);
      renditionDef.setParameterValue(ImageRenderingEngine.PARAM_COMMAND_OPTIONS, command);
      renditionDef.setParameterValue(ImageRenderingEngine.PARAM_ALLOW_ENLARGEMENT, true);
      renditionDef.setParameterValue(ImageRenderingEngine.PARAM_AUTO_ORIENTATION, false);
      renditionDef.setParameterValue(RenditionService.PARAM_DESTINATION_PATH_TEMPLATE, destination);
      renditionDef.setExecuteAsynchronously(false);

      // Check for existing rendition for given definition
      ChildAssociationRef renNode = renditionService.getRenditionByName(node, renditionName);
      if (renNode == null) {
         logger.debug("Rendition of type " + renditionName + " does not exist, creating it now.");
         logger.debug("Imagemagick command to execute: " + (String) renditionDef.getParameterValue(ImageRenderingEngine.PARAM_COMMAND_OPTIONS));
         renNode = renditionService.render(node, renditionDef);
      }
      return renNode.getChildRef();
   }

This is great. I can generate my renditions and all is well. However, whenever I <strong>update</strong> my source image, I receive errors as follows:

I have tried simply removing the RenditionService.PARAM_DESTINATION_PATH_TEMPLATE piece and allowing the renditions to be created hidden, but I get the exact same error when I update the original image.

I have also tried setting renditionDef.setParameterValue(RenditionService.PARAM_ORPHAN_EXISTING_RENDITION, true); as I don't really care what happens to the old renditions, but the results are the same.


Any input here would be great. Thanks all.

I figured out my issue. <strong>All rendition definitions must have a unique name!</strong> Learned my lesson, hope this helps someone else.
