Subject: HtmlSelectOneMenu valueChange behavior
Hi,
I have the following code in my
application, and it works, but I'm wondering if this is the right way to do
it:
public HtmlPanelGrid getPanelGrid() {
grid = new
HtmlPanelGrid();
grid.setColumns(4);
grid.setBgcolor("red");
HtmlSelectOneMenu chooser
= new HtmlSelectOneMenu();
chooser.setId("reportsOfCategory");
chooser.setOnchange("submit()");
chooser.setValue("${selector.reportName}");
chooser.setValueChangeListener(application.createMethodBinding(
"#{selector.buildControls}",
new Class[] {
ValueChangeEvent.class}));
chooser.setTitle("Please select a report to
run");
chooser.getChildren().add(ReportsPerCategoryMapper.getOptionItems(this.getCategory().getName()));
grid.getChildren().add(chooser);
//this is only for testing
grid.getChildren().add(displayCategory());
return grid;
}
public
void buildControls(ValueChangeEvent event)
{
System.out.println("I got
the report's name: " +
event.getNewValue());
}
Calling chooser.getValue() in the listener method returns null, whereas event.getNewValue() works. Could someone please explan this behavior. What is the purpose of chooser.setValue() if getting the value doesn't work? Would it be correct to do:
reportName = event.getNewValue();
or is there a better way?
TIA.
