ListMultipleChoice doesn't work when entries are preselected
------------------------------------------------------------
Key: WICKET-1337
URL: https://issues.apache.org/jira/browse/WICKET-1337
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.3.1
Reporter: Thomas Jaeckle
I tried to preselect all entries in a ListMultipleChoice:
List priorityList = getPriorityList();
lmcPriority = new ListMultipleChoice("selectContent", new Model(),
priorityList);
lmcPriority.setModelObject(priorityList);
That works, but when I now start deselecting some items or I select just one
item, the ListMultipleChoice has the wrong list.
For the szenarios I did a "System.out.println(getModelObject());" at the end of
ListMultipleChoice.updateModel()
---
First szenario:
This is my list of priorities:
[very high, high, medium, low, very low]
After I deselect (with Ctrl-Key pressed) "medium" I get:
[very high, high, low, very low]
After I deselect "high" I get:
[very high, very low]
After I deselect "very high" I get:
[] (empty List)
At this time "low" and "very low" are still selected.
---
Second szenario:
This is my list of priorities:
[very high, high, medium, low, very low]
I select only "medium":
[medium]
I select only "high":
[] (empty List)
I select only "low":
[] (empty List)
At this point I can select what I want, but the list never has entries.
---
When I don't preselect all entries, everything works fine.
