cancel page

Hi,

I am not sure if this is the right place for this question...
apologies if my post is off topic here.

Does anyone have ideas how to create a shared yes/no xhtml page?
say, we have yes and no buttons and there action is not predetermined.
For example, once you want yes button to invoke USER deletion action.
The next time you want yes button to invoke CITY deletion action.
(say USER and CITY are some entities).
I have tried to
<h:commandButton id="yesButton" value="Yes" action="#{yesButton}"/>
where I set 'yesButton' variable in the context, prior going to the yes no page.

Contexts.getConversationContext().set("yesButton", "#{userEditor.deleteUser}");

No success.

Many thanks,
Filip

If you are using facelets I suggest using source-composition components - they work a treat for that sort of task

<my:yesNoButtons yesBean="#{user}" yesAction="deleteUser" noBean="..." noAction="..." />

You have to pass in the bean and the action string seperately in current facelets version, but I think that is to be fixed soon (so you can pass a methodbinding as a tag attribute)

Hi Peter,

thanks for the quick response.
However, I am just a beginner in Facelets.
Could you please, point out some detailed example/tutorial on the topic?

Thanks,
Filip

The faceelets reference manual gives the bare bones,
https://facelets.dev.java.net/nonav/docs/dev/docbook.html#taglib-create-source
and unfortunately the facelets example have nothing on this.

So

yesNoButtons.xhtml

html xmlns="http://www.w3.org/1999/xhtml"
 xmlns:ui="http://java.sun.com/jsf/facelets"
 xmlns:h="http://java.sun.com/jsf/html">
<ui:composition>
 <h:commandButton value="Yes" action="#{yesBean[yesAction]}"/> <h:commandButton value="No" action="#{noBean[noAction]}"/>
</ui:composition>
</html>

examplePage.xhtml

...
xmlns:my="http://my.com/jsf/my"
...
my:yesNoButtons yesBean="#{user}" yesAction="deleteUser" noBean="#{city}" noAction="deleteCity" />
...

Wiring

my.taglib.xml

<!DOCTYPE facelet-taglib PUBLIC
 "-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN"
 "http://java.sun.com/dtd/faces-taglib_1_0.dtd">

<facelet-taglib>
 <namespace>http://my.com/jsf/my</namespace>
 <tag>
 <tag-name>yesNoButtons</tag-name>
 <source>yesNoButtons.xhtml</source>
 </tag>
</facelet-taglib>

web.xml

...
 <context-param>
 <param-name>facelets.LIBRARIES</param-name>
 <param-value>/WEB-INF/my.taglib.xml</param-value>
 </context-param>
...

Pub my.taglib.xml and yesNoButtons.xhtml in WEB-INF
