This issue will not advance anymore, so it is better to close it as won't fix.
If anyone has objection, it can be reopened (explaining the reasons why this
should be left open or giving hints about the direction to take)
> f:setPropertyActionListener and h:commandButton leads to

> Key: MYFACES-1695
> URL: https://issues.apache.org/jira/browse/MYFACES-1695
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 1.2.1-SNAPSHOT
> Environment: Tomcat 6.0.13, Facelet 1.1.12 / Facelet 1.1.13 snapshot,
> MyFaces 1.2.1snapshot
> Reporter: Jan Ziegler
> Assignee: Leonardo Uribe

> Im having a problem with f:setPropertyActionListener when binding the target
> to an int-field. I never had this problem when using the latest MyFaces 1.1
> and Facelets 1.1.12 which backported the
> setPropertyActionListener-functionality to JSF 1.1 Environments.
> 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 class MyBean
> {
> private int currentPage;
> ...
> 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
> Exception:
> java.lang.IllegalArgumentException: argument type mismatch

> Afterwards I changed the target-binding to String -this fixed the problem for
> my xhtml-example above. I change the Methods like this:
> public class MyBean
> {
> private int currentPage;
> ...
> public String getCurrentPage()
> {
> return String.valueOf(this.currentPage);
> }
> public void setCurrentPage(String page)
> {
> this.currentPage = Integer.parseInt(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?
