Buggy source:
@Override public void actionPerformed(TableElementButton tableElementButton,String actionID){
  if (actionID.equals("String_Node_Str")) {
    int index=Integer.valueOf(tableElementButton.getID().substring(3));
    BlockTransformerProvider provider=StructureHandler.blockTransformerProviderForID(currentTransformerType);
    BlockTransformer blockTransformer=provider.defaultTransformer();
    TableDataSource tableDataSource=provider.tableDataSource(blockTransformer);
    blockTransformerList.add(index,blockTransformer);
    navigator.pushTable(new GuiTable(tableDelegate,tableDataSource));
  }
 else   if (actionID.equals("String_Node_Str")) {
    currentTransformerType=nextTransformerID(currentTransformerType);
    tableDelegate.reloadData();
  }
 else   if (tableElementButton.getID().startsWith("String_Node_Str")) {
    int index=Integer.valueOf(tableElementButton.getID().substring(11));
    BlockTransformer blockTransformer=blockTransformerList.get(index);
    BlockTransformerProvider provider=StructureHandler.blockTransformerProviderForID(StructureHandler.blockTransformerIDForType(blockTransformer.getClass()));
    if (actionID.equals("String_Node_Str")) {
      navigator.pushTable(new GuiTable(tableDelegate,provider.tableDataSource(blockTransformer)));
    }
 else     if (actionID.equals("String_Node_Str")) {
      blockTransformerList.remove(blockTransformer);
      tableDelegate.reloadData();
    }
 else     if (actionID.equals("String_Node_Str")) {
      blockTransformerList.remove(index);
      blockTransformerList.add(index - 1,blockTransformer);
      tableDelegate.reloadData();
    }
 else     if (actionID.equals("String_Node_Str")) {
      blockTransformerList.remove(index);
      blockTransformerList.add(index + 1,blockTransformer);
      tableDelegate.reloadData();
    }
  }
}

Fixed version (ground truth):
@Override public void actionPerformed(TableElementButton tableElementButton,String actionID){
  if (actionID.equals("String_Node_Str")) {
    int index=Integer.valueOf(tableElementButton.getID().substring(3));
    BlockTransformerProvider provider=StructureHandler.blockTransformerProviderForID(currentTransformerType);
    BlockTransformer blockTransformer=provider.defaultTransformer();
    TableDataSource tableDataSource=provider.tableDataSource(blockTransformer);
    blockTransformerList.add(index,blockTransformer);
    navigator.pushTable(new GuiTable(tableDelegate,tableDataSource));
  }
 else   if (actionID.equals("String_Node_Str")) {
    currentTransformerType=nextTransformerID(currentTransformerType);
    tableDelegate.reloadData();
  }
 else   if (tableElementButton.getID().startsWith("String_Node_Str")) {
    int index=Integer.valueOf(tableElementButton.getID().substring(11));
    BlockTransformer blockTransformer=blockTransformerList.get(index);
    BlockTransformerProvider provider=StructureHandler.blockTransformerProviderForID(StructureHandler.blockTransformerIDForType(blockTransformer.getClass()));
switch (actionID) {
case "String_Node_Str":
      navigator.pushTable(new GuiTable(tableDelegate,provider.tableDataSource(blockTransformer)));
    break;
case "String_Node_Str":
  blockTransformerList.remove(blockTransformer);
tableDelegate.reloadData();
break;
case "String_Node_Str":
blockTransformerList.remove(index);
blockTransformerList.add(index - 1,blockTransformer);
tableDelegate.reloadData();
break;
case "String_Node_Str":
blockTransformerList.remove(index);
blockTransformerList.add(index + 1,blockTransformer);
tableDelegate.reloadData();
break;
}
}
