After migrating from 7.2 to 7.3 my tree of jsp files in my project lit up like a christmas tree with message "JavaServer Page File Error parsing file".

I think the problem may be related to parsing of tags in a javascript context.

In the following extract from a jsp page the parsing error occurs unless I put javascript comments before the logic tags. Wrapping the tags in jsp comments <%-- -- %> also clears the error but obviously makes the tag not function.

  <script type="text/javascript">
      
    document.login.j_username.focus();
     
    //<logic:present parameter="loginError">
    msg = "Sorry - we could not find a match for the user name and password you provided.\n" 
        + "N.B. both user name and password are case sensitive.";
    
    alert(msg);
    //</logic:present>
        
    
    function ie8Alerter() {
        
       var Y = YUI();
        // leverage boolean coercion -- 0 evaluates as false
       if (Y.UA.ie && Y.UA.ie < 9 ) {  // IE
           document.login.btnLogin.disabled = true;
           alert("We are very sorry...\n\nIE8 does not have sufficient capabilities to work with Liberty Accounts\nPlease updgrade to a current version of IE\nor use Firefox or Chrome if you are on Windows XP.");
       }  
       
    } 
    
    ie8Alerter();
        
  </script>


The problem is similar for tags in javascript in the event handlers so:

<input type="text" class="inputText26" onfocus="this.select();" name="j_username" maxlength="25">  is OK

but

<input type="text" class="inputText26" onfocus="this.select(<bean:write name="cobrandBean" scope="session" property="partnerID" filter="false"/>);" name="j_username" maxlength="25">

triggers a parsing error.

The tags only produce the error when they are parsed in a javascript context. When they are in the html context there is no parsing error.
