Buggy source:

Fixed version (ground truth):

  this.matrix.getCellFormatter().setWidth(1,1,"String_Node_Str");
  this.matrix.setWidth("String_Node_Str");
  this.matrix.setCellPadding(10);
  this.matrix.setStyleName("String_Node_Str");
  initializeRequirementFormWidgets();
  if (!CommandTypes.insert.equals(currentCommand)) {
    setRequirementFormValues(currentRequirement);
  }
  this.matrix.getCellFormatter().setAlignment(1,0,HasHorizontalAlignment.ALIGN_RIGHT,HasVerticalAlignment.ALIGN_TOP);
  if (currentCommand == CommandTypes.read) {
    loadReadOnlyRequirementForm();
  }
 else {
    loadEditableRequirementForm();
  }
  this.matrix.setWidget(1,0,requirementDescriptionLabel);
  this.matrix.setWidget(1,1,getField(requirementDescriptionTextBox));
  this.matrix.setWidget(2,1,createHTMLSubGoalList());
  this.matrix.getCellFormatter().setAlignment(1,0,HasHorizontalAlignment.ALIGN_RIGHT,HasVerticalAlignment.ALIGN_TOP);
