RE: trouble with bean returning boolean

For the archives, a reboot of Tomcat solved this problem. Still a bit 
strange, since I checked for caching or similar by modifying other 
pieces of code. No matter, lesson learned: reboot reboot reboot.

It's a convention used in beans. Methods called isSomething should be 
recognized as booleans by something in the jsp code.

Subject: trouble with bean returning boolean


Hello all,

I have trouble getting a very simple bean (o'reilly book example)  to 
return boolean values.  I call it with:

c: choose
c:when test=${foo.valid}

...


and the validation code in the bean looks like:

public boolean isValid(){
return true;
}


This generates the following error message:

org.apache.jasper.JasperException: javax.servlet.jsp.JspException: An 
error occurred while evaluating custom action attribute test with 
value ${foo.valid}: Unable to find a value for valid in object of 
class foobar.FooBarBean using operator . (null)

Everything works fine with method getName which returns a String that 
I can output with c:out.

anyone?

thanks
