newTableView insertRow scrollHeight bug

searchm · October 30, 2013, 3:36pm

Hey there,

I noticed that by inserting a new row, the tableView becomes scrollable, even when the contents height is not large enough to exceed the limits.

e.g.: Means that if you have a tableview with a height of 300px and there are only two rows each height 30px tall, and you insert a third one, you are suddenly able to scroll out of the boundaries.

well I think the problem is that the following code adds a new row height to _scrollHeight, even if this got set to the full tableView._height in case that it’s smaller then this ( Line 496 / enterFrame Method ).

Following line in function view:_insertRow( options, reRender ):

self.\_scrollHeight = self.\_scrollHeight + self.\_rows[table.maxn(self.\_rows)].\_height + 1

replaced by this

self.\_scrollHeight = ( #self.\_rows + 1 ) \* ( self.\_rows[#self.\_rows].\_height + 1 )

fixes the bug, but it still does something weird with the scrollBar itself.

please take a look.

thanks,

roman
