Using multiple AJAX calls on the same element Bootsfaces

Question

Can I do something like this:

<b:navLink  ...    onclick="ajax:callBeanMethodA;ajax:callBeanMethodB" />

Like that doesn't work, is there any way to make it work ?

Thanks

I guess your best bet it to combine these two or multiple method calls in a convenience method in your backing bean.

This way you can also make sure, that they're called in a consistent order:

public void combinedMethod() {
    callBeanMethodA();
    callBeanMethodB();
}

Then just call the single convenience method from your listener:

<b:navLink  ...    onclick="ajax:beanName.combinedMethod" />

Other advantages of this approach would be better readability and reusability and maintainability, as you defined the combined logic centrally.

That was my first thought, too. But on the other hand, it contradicts the goal of orthogonality. I didn't implement it in the current version of BootsFaces, but there's no reason to not implement it. This evening, I'd like to give it a try. — Stephan Rauh, May 23 '16 at 19:29

Actually, it does work. It's just a bit simpler than you thought. Omit the second ajax: prefix, and things work fine:

JSF markup:

<b:messages id="messages" />
<b:commandButton value="Click me!" 
                 onclick="ajax:menuView.save();menuView.reload()" 
                 update="@form">
</b:commandButton>

Java bean:

@ManagedBean
public class MenuView {
  public void save() {
    addMessage("Success", "Data saved");
  }
  public void reload() {
    addMessage("Success", "reloaded");
  }
}
