             Project: Pivot
          Issue Type: Bug
          Components: wtk, wtk-terra
    Affects Versions: 1.4, 1.5, 1.5.1, 2.0, 2.1, 3.0
         Environment: Windows XP, Java 1.6.0_17
            Reporter: Thomas Guretzki


TextInput Component: setSelection(int selectionStart, int selectionLength): 
third <if> should be:
"if (selectionStart < 0
            || selectionStart + selectionLength > (textNode == null ? 0 : 
textNode.getCharacterCount())) "
or something similar

respectively

TerraTextInputSkin's updateSelection():
definition of local variable <n> (6th line of code) should be
"int n = (textNode == null ? 0 : textNode.getCharacterCount());"
