Changes

• Added retry after dragToCell

[labkey-tchad]

This retry doesn't know enough to replicate the initial state. It assumes that a single cell is selected, which is not always the case.
In order to be able to do a retry, a method would the start and end point of the selection area. Most calls to dragFill are preceded by a call to selectCellRange. You could overload dragFill to include the selectCellRange step and retry if it fails. Something like this:

public void dragFill(WebElement selectStart, WebElement selectEnd, WebElement dragEnd)
{
    selectCellRange(selectStart, selectEnd);
    dragFill(selectEnd, dragEnd);
    /*
     check result and retry if necessary
     */
}
