Hi,

I'm getting 100<4==true - when using 2 variables while using of constant on any
position - works correctly. I had to change the code (to take one variable from
a bean and that works as well - to fix the problem in my code. But this seems
to be weird...
Tried both jakarta-taglibs-standard-1.1.2.zip and jakarta-taglibs-20060829.zip
-  behave the same.

test.jsp demonstrating the bug:
------8<------
<% 
    long x=4;
    pageContext.setAttribute("x", Long.toString(x));

    long y=100;
    pageContext.setAttribute("y", Long.toString(y));
%>
y=${y},x=${x}, ${y}&lt;${x} is ${y<x}
<br>
However if we'll change any of variables to a constant - no problem: <br>
y=100,x=${x}, 100&lt;${x} is ${100<x}<br>
y=${y},x=4, ${y}&lt;4 is ${y<4}<br>
y=100,x=4, 100&lt;4 is ${100<4}<br>
------8<------

what I'm getting in the browser:

------8<------
y=100,x=4, 100<4 is true
However if we'll change any of variables to a constant - no problem:
y=100,x=4, 100<4 is false
y=100,x=4, 100<4 is false
y=100,x=4, 100<4 is false
------8<------

thanks
Vasili
