Wizard and CheckGroup

[David Leangen <wi...@leangen.net>]

Hello.

I'm using a CheckGroup in a Wizard.

Let's say the CheckGroup is in step 2 of my Wizard:

 [1] <-> [2] <-> [3]

Going through the Wizard, during step 2, I check all the checkboxes,
then I go to step 3.

If I back up to step 2, everything remains checked.

However, if I back up again to step 1, then click next to step 2, I lose
all my checkmarks.


In the code for Check, whether or not the checkbox is checked is
determined by this:

  if (group.hasRawInput())
  {
    final String[] input = group.getInputAsArray();

    if (input != null)
    {
      for (int i = 0; i < input.length; i++)
      {
        if (uuid.equals(input[i]))
        {
          tag.put("checked", "checked");
        }
      }
    }
  }
  else if (collection.contains(getModelObject()))
  {
    tag.put("checked", "checked");
  }


When group.hasRawInput() returns false, and we fall through to the else
clause, everything works as expected.

However, when group.hasRawInput() returns true, on the next line
group.getInputAsArray() returns null. This means that the for condition
never gets executed, so my checkboxes don't get checked.

What's the story with hasRawInput()?


Thanks!
David

Why would there be raw input for the Checkbbox on page 2 when stepping
from 1 to 2? What is happening is that the checkbox is populated from
the underlying model, which happens to come up unchecked. What you
should check is: why isnt's the model updated when you first step from
2 to 3? Are you looking at the same model instance?
