KeepTogether on ListItem not implemented

[stonewoodman]

The value keeptogether on a ListItem is ignored

ListItem listItem = new ListItem("multiline text...", font);
listItem.setKeepTogether(true);

expected result The flag has the same behavior as by Paragraph.

OK, method getKeepTogether() is used in PdfDocument.add(Element) if the element is Paragraph, but not if it is ListItem, although ListItem extends Paragraph ...

public boolean add(Element element) throws DocumentException {
...
        try {
            switch(element.type()) {
...
                case Element.PARAGRAPH: {
...
                    // if a paragraph has to be kept together, we wrap it in a table object
                    if (paragraph.getKeepTogether()) {
...
                case Element.LISTITEM: {
...

does it need to be encapsulated in a table just like paragraph? as that is causing it to fail when using list item in a list component
