Jan Ziegler commented on MYFACES-1695:
--------------------------------------
Hi Mike,
this does also clear it up for me now. If I use Long-Fields it is working. But
Jetty´s EL-Implementation als seems to accept int-fields...
anyway, Long is ok for me.
Thanks!

> Issue Type: Bug
> Affects Versions: 1.2.1-SNAPSHOT

> Reporter: Jan Ziegler

> Im having a problem with f:setPropertyActionListener when binding the target

> Here´s an excerpt of the example xhtml-page:
> <h:commandButton value="click">
> <f:setPropertyActionListener target="#{myBean.currentPage}" value="1" />
> </h:commandButton>
> and here the bean (int-approach):

> ...
> public int getCurrentPage()
> {
> return this.currentPage;
> }
> public int setCurrentPage(int page)
> {
> this.currentPage = page;
> }
> ...
> }
> So when I click on the button to perform a submit I´m getting the following

> public String getCurrentPage()

> public void setCurrentPage(String page)

> so far so good, but I´m facing another problem, when having
> "calculated-expression" as the value of setPropertyActionListener like:
> <f:setPropertyActionListener target="#{myBean.currentPage}"
> value="#{myBean.currentPage - 1}" />
> then neither the int-approach nor the string-approach works. with using the
> int-binding I´m getting the same error as above and with the string-binding i
> get another IllegalArgumentException (caused by a ClassCastException):

> I also tried to use standard converters to ensure that "value" is always
> converted to an Integer or String, e.g.:
> <f:setPropertyActionListener target="#{myBean.currentPage}" value="1" >
> <f:convertNumber integerOnly="true"/>
> </f:setPropertyActionListener>
> But I also had no luck with this. It didn´t change anything.
> So whats wrong here? Do I have to ensure or convert the value somehow or
> should the jsf-implementation perform the needed convertions?
