A JavaScript error occurs when the combination of table.deleteRow() and table.insertRow() is used. The deleteRow statement is nested in a while loop where "table.rows.length > 0" controls the looping. The insertRow statement must have at least 2 rows to insert in order to see the exception. And finally, this will only occur on the 2nd call (onclick events used below) from the page. The first call succeeds.
This scenario makes me think that a variable (an index is what the JavaScript exception mentions briefly below) is not being properly reset. The HTML and webtest script are below. If possible could someone try to reproduce this? If it's a real bug, then let me know where to open it.
