Brian Leathem commented on RF-12193:
------------------------------------
The cause of this issue is in this section of the initialize code:
{code}
this.rowHeight = this.dataTableElement.offsetHeight / this.rows;
if (this.rowCount != this.rows) {
this.contentElement.style.height = (this.rowCount * this.rowHeight) + "px";
}
{code}
when the EDT is not displayed, the _offsetHeight_ is 0, so the calculated
height of the EDT is 0.
A possible fix would be to:
# absolutely position the EDT off the page,
# display it,
# calculate the offsetHeight,
# un-display it,
# re-position it.
However it is not clear how well this would work when the EDT's display is
controlled by the display property of a parent element.
