Local fix

• This is only intended for experienced users and administrators
  of Business Process Manager (BPM) and WAS. Use extreme caution
  when applying these steps. This is also only intended as a test,
  please revert the change, and obtain a formal fix from IBM.
  
  1. In a simple single server environment, locate the file
  tm_error.jsp in the BPM install profile directory,
  <BPM_install>/<Profile_name>/installedApps/<Node_name>/IBM_BPM_T
  eamworks_SampleNode01_server1.ear/teamworks.war/html
  
  where
  <BPM_install>  = Install root for BPM
  <Profile_name>  = Profile name
  <Node_name>  = Node name
  
  2. Backup the file tm_error.jsp, can be in same directory
  
  3. Edit the file tm_error.jsp, as follows,
  
  ORIGINAL CODE:
  <%@ page import="java.io.PrintWriter,
  com.lombardisoftware.core.StringUtilities,
  ...
              "parameters": [ '<% if (exception != null) { %><%=
  exception.getMessage() %><% } else { %><%=
  request.getAttribute("com.lombardisoftware.error.message") %><%
  } %>']
  
  UPDATED CODE:
  <%@ page import="java.io.PrintWriter,
  com.lombardisoftware.core.StringUtilities,
                   java.io.StringWriter,
  org.apache.commons.lang.StringEscapeUtils"%>
  ...
              "parameters": [ '<% if (exception != null) { %><%=
  StringEscapeUtils.escapeJavaScript(exception.getMessage().toStri
  ng()) %><% } else { %><%=
  StringEscapeUtils.escapeJavaScript(request.getAttribute("com.lom
  bardisoftware.error.message").toString()) %><% } %>']
  
  4. Save the file and test. The server may need to be restarted,
  and/or the browser cache cleared, but these should not be
  necessary.
  
  5. Revert to the original file.
  

Problem summary

• When exception happens in HS runtime, "Details" button does
  nothing when clicking it. The issue is caused by a syntax error
  in the Java Script of the generated HTML error page.
