Page title appended with title from another DCR

We're currently working on an issue with our site which utilizes 6.7.2. Specifically, the issue involves the site's "Share this page" link which uses a default email client and creates an email using a mailto link with the current page information. Specifically, it displays the page <title> in the body of the email along with a link to the page.

However, we've discovered that on pages using a a specific page template which contains a component that is served data using an external handler, the page title is being appended with the a page title from another DCR utilizing the same template.

The external handler sets the page <title> value by placing it into the page scope data.

Eg.

Map pageData = context.getPageScopeData();

if (StringUtils.isNotBlank(content.getTitle()))
{
  pageData.put(RuntimePage.PAGESCOPE_TITLE, content.getTitle());
}
if (StringUtils.isNotBlank(content.getSummary()))
{
  pageData.put(RuntimePage.PAGESCOPE_DESCRIPTION, content.getSummary());
}

The summary data populates without issue. However, this is used on other templates where this issue does not occur when the user clicks on the "Share this page" link.

After troubleshooting this for a while, we're at a loss in regards to the cause of this issue. Does anyone have any ideas on what could cause this or how we might troubleshoot further?

What's the problem? That it appends to the title instead of replacing it?

The issue is that the title from another DCR is being appended to the title of the loaded DCR. We're not looking to replace anything with anything.

In addition to this issue presenting itself in the email generated by the Share This Page functionality, it also appears in Search listings. So the issue seems to lie in how the page loads it's <title>.

Well by default, the page title is loaded from the .page file itself. If yours is doing anything different, then it's a result of custom code on your end. So the implication is that you have a custom controller and/or external that appends stuff to the title, apparently incorrectly. Without seeing your code base, it's hard to say where your problem is.

You should check fixed-layout.page.xsl or div-layout.page.xsl.

There is easy way to attach prefix / suffix to page title slightly modifying core layout file like fixed-layout.page.xsl or div-layout.page.xsl located at path WEB-INF/classes/com/interwoven/xsl/runtime.

These XSL file contains ,

<xsl:template match="Page_Display_Properties">
<html>
<head>
<title><xsl:text>$CONTEXT{pageTitle}</xsl:text></title>
....

....

</head>

<body>

....

</body>

</html>

</xsl:template>

Notice <title><xsl:text>$CONTEXT{pageTitle}</xsl:text></title> it can be modified to <title><xsl:text>$PAGE_SCOPE[Prefix]$CONTEXT{pageTitle}$PAGE_SCOPE[Suffix]</xsl:text></title>

From second DCR read in separate component external you can set this values using following API.

context.getPageScopeData().put("Prefix", <some_field_value_from_DCR>)

context.getPageScopeData().put("Suffix", <some_field_value_from_DCR>)

If there are .pages which do not have component (DCR) that sets Prefix and/or Suffix , then only title will appear without any backend exception.

$CONTEXT requires method getPageTitle() in backend RequestContext object. By LSDS design using $PAGE_SCOPE does not have such restriction and there is no penalty for missing value of supplied key. So you might not be getting any exceptions and code is still functional in both cases.

Pratish, thanks for your attention to this thread but unfortunately we don't want this to occur and we can't determine why it is occurring.

Yes I got that , it is something which is occuring but you don't want it. Still have a quick look at fixed-layout.page.xsl or div-layout.page.xsl, whatever you are using.

After all whatever you put in .page or code does not appear in final HTML output by magic. These XSLs might serve as first step in reverse engineering to root cause of your issue.
