h:commandButton not work

[chicochen]

2 things in one webpage:

1. <h:commandButton id="findButton" value="Filter" action="#{projectAction.find}"/>

2. <s:link action="#{projectAction.find}" value="Projects" />

also has <h:inputText id="searchString" value="#{projectAction.searchString}" size="15" />

I find "h:commandButton" cannot call "projectAction.find" method, only can set "projectAction.searchString" field to new value; but "s:link" can.

anyone could help me?

Do you have a form around the commandButton and input field?

Note that s:link does NOT do a form submission so searchString won't be updated in the model using s:link.

Possible an error in one of the earlier JSF phases.

One thing I use for debugging is this...

public class DebugPhaseListener implements PhaseListener
{
 public void afterPhase( PhaseEvent event )
 {
 System.out.println("afterPhase: " + event.getPhaseId());
 }

 public void beforePhase( PhaseEvent event )
 {
 System.out.println("beforePhase: " + event.getPhaseId());
 }

 public PhaseId getPhaseId()
 {
 return PhaseId.ANY_PHASE;
 }
}

If you configure this listener in faces-config you can see as each phase runs. It might be failing somewhere in the validate phase in which case you'll see it jump straight to the render phase.

sorry,

<h:commandButton id="findButton" value="Filter" action="#{projectQueryAction.find2}" />

should be

<h:commandButton id="findButton" value="Filter" action="#{projectQueryAction.find}" />

, but still work.

[chicochen]

i missed

public void setPageSize(int pageSize);

in it's interface, it's work now.
