Hello,

maybe someone can help us with the following issue?

We have a task inbox that should display only certain tasks by following conditions:

[b]Show Tasks when:

1. currentUser != lastUser
   OR
2. currentUser == lastUser AND processState == MODIFIED[/b]

We already implemented the getCurrentUser method, which works fine:

public java.lang.String getCurrentUser()  {
return getFacesContext().getExternalContext().getUserPrincipal().getName();
}

So in the TaskSearchProviderBindings, we were able to display only the tasks, where lastUser <> currentUser
when we configure the TaskSearchProviderBindings as following

1. currentUser != lastUser

private static final String[][] TASKSEARCHPROVIDER_PROPERTY_BINDINGS = new String[][] {
...
...
{"#{taskSearchProvider.searchQuery.isLastUser.fieldBinding}", "#{currentTask.taskData.processData.lastUser}"},
{"#{taskSearchProvider.searchQuery.isLastUser.operator}", "<>"},
{"#{taskSearchProvider.searchQuery.isLastUser.value}", "#{activePageBean.currentUser}"},

Now we have to add the second condition, but we do not know how to achieve this in here:

2. currentUser == lastUser AND processState == MODIFIED

...
{"#{taskSearchProvider.searchQuery.isLastUser.fieldBinding}", "#{currentTask.taskData.processData.lastUser}"},
{"#{taskSearchProvider.searchQuery.isLastUser.operator}", "="},
{"#{taskSearchProvider.searchQuery.isLastUser.value}", "#{activePageBean.currentUser}"},
AND
{"#{taskSearchProvider.searchQuery.processState.fieldBinding}", "#{currentTask.taskData.processData.context.processState}"},
{"#{taskSearchProvider.searchQuery.processState.operator}", "="},
{"#{taskSearchProvider.searchQuery.processState.value}", "MODIFIED",

We tried it with a java method, but can’t get the method isTaskAccessible() working.

public boolean isTaskAccessible()
{
// Check if task is accessible by user on the following condition.
// accessible:
// currentUser != lastUser OR
// currentUser == lastUser AND processState == MODIFIED

// is not working !!!
String lastUser = getTaskSearchProvider().getTaskData().getProcessData().getLastUser();
// is not working !!!
String processState = getTaskSearchProvider().getTaskData().getProcessData().getContext().getContext().getProcessState();

if (!(getCurrentUser().equalsIgnoreCase(lastUser)))
return true;
else if (processState.equalsIgnoreCase("MODIFIED"))
return true;
else
return false;
}

The result of the method isTaskAccessible() is called in the following expression:

{"#{taskSearchProvider.searchQuery.isTaskAccessible.fieldBinding}", "true"},
{"#{taskSearchProvider.searchQuery.isTaskAccessible.operator}", "="},
{"#{taskSearchProvider.searchQuery.isTaskAccessible.value}", "#{activePageBean.taskAccessible}"},

Have you thought of using Filter Rule Expressions? Have a look at the Task Engine User’s Guide and see if the section on Filter Rule Expressions might help.
