I encounter a problem when I change the columns widths of a sheet programmaticly and the user resizes the columns by mouse.
I can't describe the problem in detail but when I change the line
writer.writeAttribute(HtmlAttributes.VALUE, "", false);
for the hidden widths field to
writer.writeAttribute(HtmlAttributes.VALUE, state.getColumnWidths(), false);
in renderSheet() in the SheetRenderer the problem disappears and everything works like expected.
