How to determine which submit button was clicked from a phase listener

[Ajay Dhar]

I'm using JSF 1.2 and I need to determine which submit button was clicked from a phase listener which is triggered before JSF conversion. I am assuming that this information is available from FacesContext but I can't find it.

Previously I had to do something similar, but not exactly the same. I had to find the name of the submitted form. I used the following method in my phase listener:

public final String getSubmittedForm(FacesContext context){
        Map<String,String> map = context.getExternalContext().getRequestParameterMap();
        for(String key : map.keySet()){
              UIComponent comp = findComponentByClientId(context.getViewRoot(), key, context);
              if(comp!=null){
                    if(comp instanceof HtmlForm){
                          return comp.getId();
                    }
              }
        }
    	return null;
}

If someone could help me out I would greatly appreciate it.

Thanks,
Ajay
