I've got an auto complete combobox with a custom model that extends SimpleListModel. To get my sublist for the auto complete I override getSubModel(Object obj, int nRows). I am setting the model with an empty list to start and then fetching from the database for each submodel (the data is huge, so this way is more efficient).

I also have a renderer which sets both a label and a value to each combitem. I have an onChange event listener in the combobox where I want to get the value of the comboitem (not the label - I know I could just get that by getting the value of the combobox):

this.addEventListener("onChange", new EventListener() {

public void onEvent(Event e) throws Exception

{ Executions.sendRedirect("index.zul?bun=" + FindUsersAutoCompleteCombo.this.getSelectedItem().getValue()); }

});

The trouble is, the getSubModel method doesn't update the data in SimpleListModel, so when I try to get the value of the comboitem I get this error (remember, I started out with an empty list in the model, and it hasn't been updated):

SEVERE: java.lang.ArrayIndexOutOfBoundsException: 2
at org.zkoss.zul.SimpleListModel.getElementAt(SimpleListModel.java:92)
at org.zkoss.zul.Combobox.syncSelectionToModel(Combobox.java:609)

This could be solved simply with a setter for data in SimpleListModel, so the data can be updated in the getSubModel method. Thanks!
