Enable/Disable a link based on a column value

Question

Hi Team,
I am Using Jdev 11.1.1.5.0.
I have a link button named 'register'on first page by clicking on to which will navigate to next page where i will get the option of selecting for the courses through checkboxes.
When all the checkboxes are checked by clicking on the submit button i am able to update the checkboxes value in the backend and able to navigate to the first page.
I can count that all the checkboxes are checked.
My requirement is if all the checkboxes are checked i wanted to disable the register button other wise keep it as enable.
The data on the first page and second page are joined using a view link.
the data on the first page contains employee records and the data on the second page contains record for the courses selected for the corresponding employee.
Please let me know what is the correct approach for it.
Kindly guide me in it.
Thanks,
Ajay

Answer 1

Which scope is the bean defined in?
You can put the bean in pageFlowScope. This way it can be accessed from both pages. Now you implement a method in the bean which returns the count or better a method which make the decision if all check boxes are checked and returns true if yes and false otherwise.
The signature of the method looks like
    public boolean isAllChecked()
        // calculate if all marks are checked
        return true;
    }and in your page you access the method on the disabled property like
              <af:commandButton text="commandButton 1" id="cb1"
                                disabled="#{pageFlowScope.YUOT_BEAN.allChecked}"/>Timo
