No matter if I set it 

pageContext.setAttribute("errmsglength", new Integer(errmsglength));

or like this

<c:set><%=errmsglength%></c:set>

No dots, nada. 
I will create a fresh project that simulates the current situation and see
if it shows the same behavior... That might allow me to track down the
problem.

At least, I learned that EL is somewhat picky about what it sees and what
not ;)

Thanks anyway guys... I'll post again, if/when I found the reason for this

or you can do something like:

<c:set><%=variable%></c:set>

you need to put appropriate attributes on the c:set tag of course.
