I declare a variable declaration block of code and code completion does not 
provide that variable in its list of defined variables in any other scriplet 
tags. i.e.

<%! MyClass var = new MyClass(); %>
<!-- Some HTML -->
<%= //var is not available in the code completion list here %>
<% //var is not available in the code completion list here %>

If I declare the variable inside of the scriptlet block then the variable is 
available in the code completion list while I am inside that same blocak of 
code. If I open another scriplet then the variable is no longer visible in the 
code completion list. i.e.

<% MyClass var = new MyClass();
//In here var is in the code completion list
%>
<!-- Some HTML -->
<%= //var is not available in the code completion list here %>
<% //var is not available in the code completion list here %>
