Leonardo Uribe commented on MYFACES-3011:
-----------------------------------------
I have checked the provided file and the syntax is invalid. The converterId for
javax.faces.convert.EnumConverter is javax.faces.Enum, but in this case we need
to set converter targetClass property.
One alternative is use a binding like this:
<h:selectOneMenu value="#{enumBean.selection}"
converter="#{enumBean.categoryConverter}">
<f:selectItems value="#{enumBean.categories}"/>
</h:selectOneMenu>
and on the bean (Category is the enum):
public enum Category {
......
}
public Converter getCategoryConverter()
{
if (categoryConverter == null)
{
categoryConverter = new EnumConverter(Category.class);
}
return categoryConverter;
}
the #{enumBean.categories} expression is bound using this code in the bean:
public Category[] getCategories()
{
return Category.class.getEnumConstants();
}
There is an error on MYFACES-2920 to be solved soon related, but this report is
not valid, so I have to close it as invalid.
