[mapguide-users] IE, AJAX and Tooltip Images

[Farah]

Hi,

 

I was trying out a tooltip: which displays an image as well as an iframe.
The tooltip with just an image (it is set programmatically) works fine in
both IE as well as Firefox. If the source of  the IFRAME points to an html
page, then also it works fine in both the browsers. However, if the source
of the iframe points to a jsp page, then the below mentioned problem occurs
in the case of IE. The tooltip keeps flickering and the mgserver dies after
a while. It works fine in the case of :Firefox as well as the Autodesk
studio preview pane, though.

 

 

Regards

Farah

Yes, that thread talks about the problem a bit.  But, the original issue was
raised (and I believe enterered in Project Tracker) almost a year ago when
both I and Juan Butler had the problem.  We, including a couple of the
Autodesk developers, were able to readily replicate it and only happens when
referencing images in the tooltip.  Other HTML elements appear to be OK,
except for the case that Scott noted below.  I've tried it without the image
and with a pile of other HTML, and those instances worked fine.

Andy,

  I remember this problem from a previous thread.

http://www.nabble.com/Properties-Frame-in-Studio-2007---Hyperlinks-tf3126334
s16610.html#a8662120

But I guess you may be right because if I'm not mistaken your site used the
image in the html tooltip. 

I wonder if it is associated with html tooltip? And would replicate without
the image also.

Brad

Hi Scott,

 

I haven't seen that before with non-image HTML in the tooltip.  I played
with it for awhile on my end and could not replicate that using HTML <table>
elements.  It may have to do with the speed of the data retrieval through
FDO during the individual AJAX call backs.  If it is slow enough to respond,
I could see where the behavior may be similar to what I'm seeing with
images.

 

I did enter a ticket into Trac for this, so hopefully we'll see some
attention to this item in the near future.

 

Andy

Hi Andy,

 

I experienced the flickering tooltip on IE without referencing an image. In
my case, I was trying to display a two-column <table> element with a few
rows, displaying a set of property/value pairs for the selected object. On
Firefox it works great, on IE the tooltip flashes continuously. Have you
seen this behavior?

This was a topic many months (or more like a year) ago.  When images are
referenced in the tooltip for a layer, the AJAX viewer with Internet
Explorer can yield some very odd results.  If it takes too long for the
image to be returned, say more than 4 or 5 seconds, it's like it tries to
call the image again and then this causes a loop which makes the tooltip to
appear to blink.  For an example that I just ran into, see
<http://mapguide.spatialgis.com/mapguide/spokanemaps/>
http://mapguide.spatialgis.com/mapguide/spokanemaps/.  When you float your
mouse over one of the camera symbols, a DOT traffic camera image should
appear, but often times results in the above behavior.  This works just fine
in Firefox.

Should I enter this as a bug into Trac?  I think it had been previously
entered into Project Tracker so I don't want to duplicate anything.  Thanks.
