Validation error message is not displayed for an attribute as an Input List Of Value

Question

Hi everyone,
I use jdev 11.1.1.7.0
In my application I've created an Entity Obj and a View Obj base Employees table.
for the JobId attribute I've taken actions as listed below:
1. in Employees EO I've created a validation for this attribute and in some cases an error message returns (the error message is "the salary is not high"):
     * Validation method for JobId.
    public boolean validateJobId(String jobid) {
        if (...) {
            return false;
        if (...) {
            return false;
        if (...) {
            return false;
        return true;
2. in Employees VO  I've created a LOV for this attribute (the view accessor is JobsViewObj ) and I display the attribute as an Input Text with List Of Values.
in jspx page I drag& drop this attribute as below:
          <af:inputListOfValues id="jobIdId"
                                popupTitle="Search and Select: #{bindings.JobId.hints.label}"
                                value="#{bindings.JobId.inputValue}"
                                label="#{bindings.JobId.hints.label}"
                                model="#{bindings.JobId.listOfValuesModel}"
                                required="#{bindings.JobId.hints.mandatory}"
                                columns="#{bindings.JobId.hints.displayWidth}"
                                shortDesc="#{bindings.JobId.hints.tooltip}"
                                autoSubmit="true">
            <f:validator binding="#{bindings.JobId.validator}"/>
          </af:inputListOfValues>
I open the Popup and I select a row from the Popup list and then I click Ok. After that if the validation method(validateJobId) returns false, the error message("the salary is not high") must be show to the user. but the error message doesn't display. I don't understand why this happens.
Can anybody guide me about this problem?

Answer 1

yes, you're right, I've tested it in 12.1.3 and error message was displayed.
it seems it's a bug(bad bug ) in both 11.1.1.7 and 12.1.2. and now what can I do? is there any way to display the the error message?
