anna-lenasundin Jul 8, 2011 7:58 AM (in response to juankprada)Hi,
I don't get any error messages.
<a4j:commandButton value="Save" ajaxSingle="true"
action="#{bean.update}"
actionListener="#{navigationBean.setPage}"
oncomplete="if(!#{bean.storeOutcome})Richfaces.showModalPanel('messageWindow');"
reRender="messageWindow" >
<f:param name="current" value="/xxx/show.jsp" />
</a4j:commandButton>
Thanks

5. Re: Navigate to another page, a4j:commandButton
juankprada Jul 8, 2011 9:48 AM (in response to anna-lenasundin)I think i understand what you are doing, but can you tell me what is the value of Constants.FAILURE_OUTCOME and Constants.SUCCESS_OUTCOME?
What I think you are doing is when you click on the button, the action listener should be executed, and 'page' parameter should be set. Not sure where you are using that parameter, but i guess it is not that important. Now, after the actionListener executes, the action method should be executed, that is the one that will send your app to the new page right?. I see that in the method updateXX() which is the one i think is executed in the action parameter, has an extra }. If its like that, it should not even compile. Now you validate a xxx variable that is not declared in that code, can you show the complete code to see what is this variable holding? and where are you setting it?
I would replace the f:param with f:setPropertyActionListener. so your NavigationBean should look something like this
public abstract class NavigationBean extends BaseBean {
protected String page;
protected String popup;
protected String script;
public void setPage(String page) {
this.page = page
}
public String getPage() {
return page;
}
.....
}
And your xhtml would look something like this:
<a4j:commandButton value="Save" ajaxSingle="true"
action="#{bean.update}"
actionListener="#{navigationBean.setPage}"
oncomplete="if(!#{bean.storeOutcome})Richfaces.showModalPanel('messageWindow');"
reRender="messageWindow" >
<f:setPropertyActionListener target="#{navigationBean.page}" value="/xxx/show.jsp" />
</a4j:commandButton>
Without the appropriate code i can't really help you.
