Task priority is set with TextBox in "Quick New Task" / with ListBox in "Task Details"

Description of problem:
There's an inconsistency in the GUI when setting the task:

1) In QuickNewTaskViewImpl the taskPriorityListBox is declared as TextBox

2) In TaskDetailsPopupViewImpl the taskPriorityListBox is declared as ListBox

Although both should serve the same purpose (setting the task priority) they don't work the same.
E.g. when creating new task it is possible to set priority 999999999, while ListBox only enables priorities 1-10

Version-Release number of selected component (if applicable):

How reproducible:
Always

Steps to Reproduce:
1. Go to Tasks > Tasks List
2. Add new task - there is simple text box for setting task priority
3. Edit this newly added task using task details (magnifying glass icon) - in the Details modal there is list box with priorities 1-10 only

Actual results:

Expected results:
I don't know what are the permissible values for task priority in jbpm (1-10?) but the same widget should be used in all the places manipulating the task priority.
