Combobox clearing value issue

Question

I've stumbled on an issue with Comboboxes in javafx2.2. This is the scenario: - Users click on the 'editFile' button. - Another pane becomes visible (with the setVisible method). This pane contains 6 comboboxes. Three of them have fixed items: cboReport, cboSales, cboSend. Three of them get their data from a db (ObservableList) and get populated when the pane becomes visible: cboFile, cboCustomer, cboVet - The user selects a file number from the cboFile. The rest of the comboboxes are beeing set with the correct values. - The user presses the save button, the file gets saved as intended. - Next the user presses a close button. When the window closes, the data on the pane gets resetted through a resetGUI_editFilePane() method. There is have lines like: ``` ... cboReport.getSelectionModel().clearSelection(); cboSales.getSelectionModel().clearSelection(); cboSend.getSelectionModel().clearSelection(); cboFile.getSelectionModel().clearSelection(); cboCustomer.getSelectionModel().clearSelec…

I ran into nearly the exact same situation and came across your question while looking for a solution. Fortunately, I came up with a workaround that forces the ComboBoxes to reset. When you reset the data on your pane, instead of doing something like:

```
cboVet.getSelectionModel().clearSelection();
cboVet.getItems.clear();
```

do something like this...

```
parentNode.getChildren().remove(cboVet);
cboVet = new ComboBox();  // do whatever else you need to format your ComboBox
parentNode.add(cboVet);
```

You'll also need to do a setItems() again on your ComboBox so the new one will be populated. This is not an ideal solution but it seems to be working as I expect the provided clearSelection() method would.
