fxml LoadException only when using MouseEvent ! (Java + Scene Builder)

Question

I have a problem, i have an event handler that should do some code, apart from the code, the event handler accepts a MouseEvent and the event that will invoke it is onMouseClicked event, Everytime i try to run the program i get an exception, if i remove the MouseEvent and leave it empty or put any other type of event like just Event or ActionEvent it works, but this is not logical plus i need the mouse event because i will then check which mouse button is clicked in my code. i reviewed other people having the same questions and i did all what was in the answers to them but didn't work.

Exception + Stacktrace:

    javafx.fxml.LoadException: Error resolving onMouseClicked='#maginfyRecord', either the event handler is not in the Namespace or there is an error in the script.

The event handler is as follows:

    @FXML
        public void magnifyRecord(MouseEvent event) {
            if ((event.getButton()== event.BUTTON2)) {
                TextArea area = new TextArea();
                area.setText(selectedTable.getSelectionModel().getSelectedItem().toString());    
                JFXPopup popup = new JFXPopup();
                popup.setPopupContent(area);
                popup.show(selectedTable);
                popup.show(selectedTable, event.getX(), event.getY());
            }     
        }

and here is the fxml for this portion:

<Tab fx:id="toDoListTab" onSelectionChanged="#switchTab" text="To Do List">
               <content>
                  <StackPane prefHeight="150.0" prefWidth="200.0">

               </content>
            </Tab>
            <Tab fx:id="notesTab" onSelectionChanged="#switchTab" text="Notes">
               <content>

            </Tab>
            <Tab fx:id="contactsTab" onSelectionChanged="#switchTab" text="Contacts">
               <content>
                  <StackPane prefHeight="150.0" prefWidth="200.0">
                     <children>
                        <TableView fx:id="contactsTable" onMouseClicked="#magnifyRecord" prefHeight="200.0" prefWidth="200.0" />
                     </children>
                  </StackPane>
               </content>
            </Tab>
            <Tab fx:id="locationsTab" onSelectionChanged="#switchTab" text="Locations">
               <content>
                  <StackPane prefHeight="150.0" prefWidth="200.0">
                     <children>
                        <TableView fx:id="locationsTable" prefHeight="200.0" prefWidth="200.0" />
                     </children>
                  </StackPane>
               </content>
            </Tab>
            <Tab fx:id="productsTab" onSelectionChanged="#switchTab" text="Products">
               <content>
                  <StackPane prefHeight="150.0" prefWidth="200.0">
                     <children>
                        <TableView fx:id="productsTable" prefHeight="200.0" prefWidth="200.0" />
                     </children>
                  </StackPane>
               </content>
            </Tab>

I tried commenting out the code completely, no change, it only works if i remove the MouseEvent or replace it with any other event

I am using Netbeans + JDK 8 + Scene Builder + jfoenix library

Answer 1

Try checking your imports, you must've imported the wrong MouseEvent. You should import

javafx.scene.input.MouseEvent

for the event handler and not any other MouseEvents.
