java.lang.IllegalArgumentException: page parameter may not b

[mikeluu]

I am trying to do the following:
1. from page content.xhtml, there is a link to edit the contents of that page

<h:outputLink value="/edit/edit_content.seam">
 <f:param name="id" value="#{contentView.content.id}" />
 Edit Content
</h:outputLink>

2. i get redirected to edit/edit_content.seam to edit content

3. there is a save button on the edit_content page defined with:

<h:commandButton action="#{editView.saveAction}" value="Save">
 <f:param name="id" value="#{editView.id}" />
</h:commandButton>

4. when i click on the Save button, I get the IllegalArgumentException. IS THIS A BUG? IF NOT, HOW CAN I REDIRECT BACK TO content.xhtml WITH THE content id param? I have tried to set the outcome of saveAction to be "/content.xhtml?id=#{editView.id}", but i get the same result. i have tried to concat the content id explicitly, but that results in the same issue.

I have the following pages.xml configuration:

<page view-id="/content.xhtml" action="#{contentView.populate}">
 <param name="id" value="#{contentView.id}"/>
</page>

 <page view-id="/edit/edit_content.xhtml" action="#{editView.populate}">
 <param name="id" value="#{editView.id}"/>
 <navigation from-action="#{editView.saveAction}">
 <rule if-outcome="success">
 <redirect view-id="/content.xhtml">
 <param name="id" value="#{editView.id}"/>
 </redirect>
 </rule>
 </navigation>
 </page>

editView and contentView beans are PAGE scoped and javax.faces.DEFAULT_SUFFIX=.xhtml.


Thanks for your help in advance!

Please don't write things like "is this a bug" in all caps. It is not a bug in this case, and I have never once in 5 years of involvement in user forums like hibernate.org or jboss.com, seen a single case where a user who claimed to have found a bug in all caps had actually found a bug.

The h:commandButton control does not support f:param in JSF, so you should use s:button instead.

my apologies, i didn't mean to emphasize that this is a bug, and in no way am i pointing fingers. sorry.

to put it succinctly, i am trying to go from page A to page B back to page A. from page B, i am submitting a save via a command button and after saving the data, i would like to get back to page A displaying the content identified by id. the data is saved correctly, but i am trying to get back to page A.

i will try to use the s:button per your suggestion.

thanks!

s:button results in the same exception.

perhaps i would help if i included the entire stack trace. :)

If you have declared a page parameter, you do *not* need to include it explicitly in links or buttons that link or submit to that page. It gets added automatically.
