Problem with HtmlSelectOneMenu onChange Event

[kapil29]

Hi

I have a HtmlSelectOneMenu contains the list of item (response type), and I have another HtmlSelectItem drop down for Correct Anser, After chaning the value from response type select box i need to disabled the second Drop down (Correct Answe). All this is created in Java Custom classes.

Please see the below code

HtmlSelectOneMenu mnuResponseType = new HtmlSelectOneMenu();
                mnuResponseType.setId(questionId + "ResponseTypeMenu");
                mnuResponseType.setValueExpression("value", application.getExpressionFactory().createValueExpression(context.getELContext(), "#{projectBean.questions["+i+"].responseType}", String.class));
                //mnuResponseType.setOnchange("updateQuestionnairePreview(event);setCorrectAnswerEnabled('"+questionId+"Panel');resetCorrectAnswer(document.getElementById('"+questionId+"CorrectAnswerMenu'), this.value == 2);");
                mnuResponseType.setStyleClass("questionType");

                UISelectItem itemRadioButton = new UISelectItem();
                itemRadioButton.setId(questionId + "ResponseTypeMenu_RadioButton");
                itemRadioButton.setItemValue(1);
                itemRadioButton.setItemLabel("Select One (Radio Button)");
                mnuResponseType.getChildren().add(itemRadioButton);

HtmlSelectOneMenu mnuCorrectAnswer = new HtmlSelectOneMenu();
                mnuCorrectAnswer.setId(questionId + "CorrectAnswerMenu");
                mnuCorrectAnswer.setValueExpression("value", application.getExpressionFactory().createValueExpression(context.getELContext(), "#{projectBean.questions["+i+"].correctAnswer}", String.class));

                mnuCorrectAnswer.setValueExpression("disabled", application.getExpressionFactory().createValueExpression(context.getELContext(), "#{projectBean.questions["+i+"].isMultiSelect}", Boolean.class));

                //mnuCorrectAnswer.setOnchange("updateQuestionnairePreview(event);");
                mnuCorrectAnswer.setStyleClass("correctAnswer");

                UISelectItem itemOpinion = new UISelectItem();
                itemOpinion.setId(questionId + "CorrectAnswerMenu_Opinion");
                itemOpinion.setItemValue(0);
                itemOpinion.setItemLabel("None (i.e., Opinion Based)");
                mnuCorrectAnswer.getChildren().add(itemOpinion);

                for (int j = 0; j < answers.size(); j++) {
                    UISelectItem item = new UISelectItem();
                    item.setId(questionId + "CorrectAnswerMenu_A" + (j));
                    item.setItemValue(j+1);
                    item.setItemLabel("" + (j+1));
                    mnuCorrectAnswer.getChildren().add(item);
                }

Kindly help to sort out this issue..

Thanks

which scope projectBean has? Disabled should be stored between requests so it should live longer than request. but If your properties which holds components instances placed in the same bean - them should be moved out to some request scoped object as usage session scoped bindings could cause different problems in JSF.

ProjectBean is stored in request scope.......
