Question:
When I add or remove and item to the text array in my list dialog then call DrawNow() the dialog is not updated and does not reflect the addition or removal.

Answer:
There are two methods in the class CEikListBox::HandleItemAdditionL() and HandleItemRemovalL() that need to be called after an addition or removal to ensure the list dialog is updated correctly.

After adding or removing an item call the relevant method before calling DrawNow() to ensure the list dialog updates itself with the change.
