>             Project: JBoss Tools
>          Issue Type: Bug
>          Components: Seam
>    Affects Versions: 2.1.2, 3.0.0.alpha, 3.0.0.beta1
>         Environment: Latest nightly build of JBoss Tools. On eclipse 3.4 SR1. JSF/Facelets/Richfaces/Seam 2.1.x environment
>            Reporter: Tim Evers

>             Fix For: 3.1.0.M4

> JBoss Tools does not validate method EL expressions properly if the method name starts with 'is'
> If I have a method in my SEAM bean like this.
> public boolean isEditButtonDisplayed() {
>     return true; //removed what this method actually does for example
> }
> and then I have in my xhtml this:
> <gekko:commandButton
>     id="tenureEditButton"
>     value="Edit"
>     action="#{TenureKeyController.editButtonClicked()}"
>     rendered="#{TenureKeyController.isEditButtonDisplayed()}" />
> When I validate this it says: "isEditButtonDisplayed" cannot be resolved.
> It looks like when the validation method sees the word 'is' it automatically thinks that the expression is a value expression. This should not be the case. Infact if I end my expression witih '()' it should always look for a method.
> The behaviour of the EL validation should be exactly the same as what happens when I run the system. But this is not what is happening. If I change my code to what the JBoss Tools autocomplete says to it actually breaks the application. According to JBoss Tools it says I should have this.
> <gekko:commandButton
>     id="tenureEditButton"
>     value="Edit"
>     action="#{TenureKeyController.editButtonClicked()}"
>     rendered="#{TenureKeyController.editButtonDisplayed}" />
> Which of course will not work when the app is deployed.
> This is somewhat related to: https://jira.jboss.org/jira/browse/JBIDE-2673 just a different scenario.
> The fundamental problem is that the rules of validation are not the same as a running app.
