TWebStringGrid ColAlignment not found

WEB TMS WEB Core
3

Still a problem (version 1.91) if compiled for Release and fixedcols=1.
If compiled for Debug it actually works fine with fixedcols. Kind of strange...
Javascript error message: "Uncaught ReferenceError: j is not defined at Object.rtl.module.rtl.createClass.UpdateGridAlignment ...."

Another problem is I cannot set rowcount inside beginupdate ... endupdate.

This does not work properly:

  grid.beginupdate;
  try
    grid.rowcount:=100;
    ....
    ....
  finally
    grid.endupdate;
  end;

but this works fine:

  grid.rowcount:=100;
  grid.beginupdate;
  try
    ....
    ....
  finally
    grid.endupdate;
  end;
