Exception when using ch.ivyteam.ivy.scripting.objects.List on Primefaces

Question

Hi all

I'm using primefaces 5 with HtmlUserDialog, in my page i'm using <p:selectmanycheckbox> that binding with a instance of ch.ivyteam.ivy.scripting.objects.List, for example:

p:selectManyCheckbox value="#{data.selectedWeeklyDayList}" layout="pageDirection">                                                   f:selectItems value="#{data.listWeekDay}" var="weekDay" 
    itemValue="#{weekDay}"
    itemLabel="#{weekDay.value}"/>  
/p:selectManyCheckbox>

And selectedWeeklyDayList and listWeekDay are instances of ch.ivyteam.ivy.scripting.objects.List. When i submit this page, after several times, i got this exception:

IllegalAccessException: Class javax.faces.component.UIComponentBase can not access a member of class ch.ivyteam.ivy.scripting.objects.List with modifiers "private"
 RuntimeException: java.lang.IllegalAccessException: Class javax.faces.component.UIComponentBase can not access a member of class ch.ivyteam.ivy.scripting.objects.List with modifiers "private"
 IllegalStateException: Error restoring component: addNewEditForm_5649:selectedWeeklyDayList

Now i just have temporary solution to avoid this exception is i change from ch.ivyteam.ivy.scripting.objects.List to java.util.List

Why do i face this issue? and is there any solutions to avoid it but i still can use ch.ivyteam.ivy.scripting.objects.List? because i need to use some features of this class (for ex: clone() method)

Thanks all.

Thanks for your support it's problem because ivy list make it's constructor to be private then other caller can not create new instance. It's also a issue in JIRA of IvyTeam (https://jira.axonivy.com/jira/browse/XIVY-427) And it has been fixed in version 6.0.2 revision 50953

Seems your getter and setter of data.selectedWeeklyDayList is private.

To your clone() problem. The interface List does not implement Cloneable. You have to use the actual Object. For example ArrayList.

List<Object> list = new ArrayList<Object>();
list.clone(); <-- doesn't exist
((ArrayList) list).clone(); <-- unchecked cast to ArrayList. ArrayList implements Cloneable.

or you use ArrayList itself.

ArrayList<Object> list = new ArrayList<Object>();
