disable s:link based in datatable

[gebuh]

I'm trying to enable or disable a link in a datatable based on a users status:

s:link view="/SomeTable.xhtml"
                        value="edit"
                       propagation="none"
                    id="canEdit"
                    rendered="#{validationAction.getIsValidUser}">
                <f:param name="someSysid"
                        value="#{_aPerson.sysid}"/>
            </s:link>

so if validationAction.getIsValidUser returns true, the link is rendered.  The method it's tied to just returns a random true or false:

public boolean getIsValidUser(ValueChangeEvent uiEvent) {
              //temporary for testing
               Random generator = new Random();
               int r = generator.nextInt();
               if(r%2 == 0){
                    this.isValidUser = true;
               } else {
                    this.isValidUser = false;
               }
               return this.isValidUser;
          }

but no matter what I do, or where I put it(as output, value, etc) I keep getting:
javax.el.PropertyNotFoundException: /startingtable.xhtml @366,46 value="#{validationAction.getIsValidUser}": Property 'getIsValidUser' not found on type package.ValidationAction_$$_javassist_seam_23

I have other methods in this class that work fine elsewhere.

I'm running seam 2.2.0, with jsf, hibernate, and not a lot of experience with seam.

any idea what I'm doing wrong?

getIsValidUser isn't really a property, that might be a hint. Try calling it specifically as a method, as in:

validationAction.getIsValidUser()

Beth,

You are calling a method getIsValidUser() without a parameter in the rendered attribute, while your method getIsValidUser has a parameter of ValueChangeEvent.

That was it, I was copying another bit of code, but it was in the form of
valueChangeListener="#{someClass.someMethod_also_with_parameters}
Why is that different?
