HTMLSerializer does not correctly detect and add # + subscribeId to hrefs/actions

In uPortal 3.1 urls are not correctly written with '#' + subscribeId
I found the problem in HTMLSerializer.appendAnchorIfNecessary()

The algorithm searches for ".render." but urls look like: /render.userLayoutRootNode.target.u34l1n9.uP in our instance. We're running under the ROOT context. I vaguely remember that it may have had uPortal.render.userLayoutRootNode before when under /uPortal context root.

I rewrote the method to look like this and verified that it works:

protected String appendAnchorIfNecessary(String elementName, String attributeName, String attributeValue) {
if (anchorId != null) {
// looking for an <a> or <form> tag element
if (elementName.equalsIgnoreCase("a") || elementName.equalsIgnoreCase("form")) {
// found an <a> or <form>, let's peek at the attributes it contains
// does it contain either an "href" or "action" attribute
if (attributeName.equalsIgnoreCase("href") || attributeName.equalsIgnoreCase("action")) {
// found the attribute, now lets make sure it points back to a channel
// check for an existing anchor ..
// check that it doesn't contain # or javascript:
/*

• Arlo's Notes:

• used to be ".render." but didn't work.

• Changed to "render.userLayoutRootNode.target" to be more specific.
  */
  if (attributeValue.indexOf("render.userLayoutRootNode.target.") != -1
  && attributeValue.indexOf("#") == -1
  && attributeValue.indexOf("javascript:") == -1){
  // this link points back to a channel, so let's
  // rewrite it and place back into the Attribute Object
  attributeValue += "#" + anchorId;
  }
  }
  }
  }
  return attributeValue;
  }
