f:setPropertyActionListener and h:commandButton leads to
IllegalArgumentException
----------------------------------------------------------------------------------
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 1.1.13 snapshot, MyFaces
1.2.1snapshot
Reporter: Jan Ziegler
Im having a problem with f:setPropertyActionListener when binding the target to
int-field. I never had this problem when using the latest MyFaces 1.1 which
backported the setPropertyActionListener-functionality to JSF 1.1 Environments.
Here´s 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:
the bean (string-approach):
public class MyBean
{
private int currentPage;
...
public String getCurrentPage()
{
return String.valueOf(this.currentPage);
}
public void setCurrentPage(String page)
{
this.currentPage = Integer.parseInt(page);
}
...
}
But I´m facing another problem, when having "calculation-expression" as the
value of setPropertyActionListener like:
<f:setPropertyActionListener target="#{myBean.currentPage}"
value="#{myBean.currentPage - 1}" />
then neither the int- approch nor the string-approch works. with using 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?
