AjaxCommandButton

[kslm23]

Hi,
is it possible to invoke AjaxCommandButton as a UIComponent from java code. I am constructing my JSF GUI components in Java as opposed to jsp due to some GUI complexity. I tried to invoke the code below (using both AjaxCommandButtonTag and AjaxCommandButton) and the exception was thrown at runtime saying that the child wasn't an instance of UIComponent. I was thinking that there must be a way to do it from java. Please share your thought on this issue.
HtmlPanelGrid panelGrid = new HtmlPanelGrid();
AjaxCommandButtonTag btn2 = new AjaxCommandButtonTag();        
btn2.setTitle("testing");          
panelGrid.getChildren().add(btn2);

Thanks!

Any of Ajax4jsf tag can be invoked from java code. For a4j:commandButton, the right class is:

org.ajax4jsf.ajax.html.HtmlAjaxCommandButton

 

The corresponding class for each of the ajax4jsf component will be mentioned in the final version of the documentation.

 

For now, there is a simple tip:

ajax4jsf.jar has two key files in the META-INF/ folder: a4j.taglib.xml  and faces-config.xml

In the a4j.taglib.xml  you can find a component-type. Then, in the faces-config.xml the implementation class by this type.

Hi,

        I have similar question too.

I am using jsf popup to display some messages. Now I want to invoke this popup when some exception or error occurs in backend(controllers) & pass the user's action(yes/no/cancel) back to backend.

User may click some link which might take long time & may fail too, in this case error msg should be popped up. Depending on user's action(yes/no), it should allow preceding operations.

How should I accomplish this?

One way I think is, by inserting hidden variable & javascripts template in component renderer & rename elements on the fly & store user response in that hidden field. I think there should be some standard approach too.
