[jboss-user] [JBoss Seam] - Re: javax.el.ELException , unable to localize the error
Hi, is it possible, you are getting some where an uncaught exception (i would say null pointer) and seam interceptor rolls back the transaction? In the next step your page will rerender and touch a really null (or corrupt) objects.

I must say, finally, that petemuir's version was correct : anonymous wrote : ajax4jsf namespace isn't being resolved correctly The problem is solved now, thanks.

Is that the whole exception? Use your debugger and break on ELException.

"petemuir" wrote : Is that the whole exception? Use your debugger and break on ELException. Yes, that's the whole exception. I am not yet experienced enough with Eclipse IDE to use debugger with JBoss. I will try to master it ASAP, but exception trace must be more informative. The good style of programming is when top-message of stack trace explains what is wrong, exactly. "find" is a method of SFSB annotated as Seam component. Other methods of this component are successfully invokable from web-page (I checked that by commenting calls to "find"), so component itself is visible. And it seems weird to me that "find" is called "property" in error message .

When I comment the link to #{partSearch.findParts} (command button code), page
is displayed fine , although calls to other partSearch methods exist in this
page.

It looks to me like the ajax4jsf namespace isn't being resolved correctly. Does it work as a h:commandButton?

Is your findPart method declared in the PartSearch interface ?

Yes

I've just played a bit with (un)commenting references to partSearch component
in xhtml page.
Interesting results :
action="#{partSearch.findParts}" - throws Exception
actionListener="#{partSearch.findParts}" - throws Exception
value="#{partSearch.pageSize} - works
action="#{partSearch.nextPage}" - throws Exception
rendered="#{partSearch.nextPageAvailable}" - works
Looks like property-invoking methods works but action-methods of type void does
not work.
Any ideas ?
