WB16: Last line in table not visible

Startbeitrag von Piet van Zanten am 07.06.2011 09:17


I'm making my first steps in the world of Webdev. :cool:
Unfortunately I'm facing something that could be a nasty bug.
I'm using several Ajax tables, linked to a query, display only, no edit, no selection.
The tables are Ajax enabled because I like the vertical scrollbar.
None of the tables display the last line of the table content :confused:
In some cases there's a very small top part of the last line visible, but no further scrolling possible. (tested in IE8, Firefox 4, Safari and Chrome)
The tables are on different tabs on the same page.
Has anyone got the same or similar problems?



Hi Piet,

I've encountered this as well when moving to WB16 but never got a satisfying solution...

Hi Peter,

I have kinda solved it by increasing the margin between the bottom of the table and its container. I also noticed that the positioning of controls is not rock solid, so it seems wise to leave some extra margins here and there and not design "on the edge".
Having done quite some manual html design, I can appreciate how hard it is to make a sophisticated tool like Webdev work.

Re: WB16: Last line in table not visible - SOLUTION

It turns out a similar problem still occurs with WB17.

IE8 will often not allow a user to select the last line of a Table when it is configured with the "Unlimited Number of Lines" option Enabled.

I have discovered this is due to the way IE fails to correctly render a horizontal scroll bar when one is required.

I suspect IE merges the horizontal scroll bar into the last row of the table which in turn traps the user's mouse clicks.

There work-arounds to fix this are:
1. ensure the right hand column is well inside the right table boarder so IE doesn't even try and render a horizontal scroll bar.
2. or turn off the Automatic Horizontal Scroll Bar and set to "Yes" so the bar is always visible. IE does render the scrollbar correctly in this case.
3. or set the Horizontal Scroll Bar option to "No" so IE never tries to render it.

FWIW my tests show this bug only affects IE so far. Opera and Chrome worked perfectly when the setting is "Automatic".

Can you post a link to an example table where this happens?

Hello Geoff

Unfortunately I don't have an externally facing website that I can load an example onto for you.

However I have make a quick Screencast video that:
1). demonstrates the IE bug happening.
2). explains what to change in WB to avoid it

I was going to have a look at it with FireBug and see if the css could be tweaked to display the last line, since it sounds like a formatting rather than a data retrieval error.

Liked your video though, explains the problem and solution very well!

Never knew a French accent sounded like that :-)
