[mapguide-users] Problems with selection

[Mark Pendergraft]

What about zooming to the feature using the maps Zoom to selection
method:

ExecuteMapAction(10);

Does the map zoom to the correct feature?  Is it highlighted afterwards?

Is there a solution to the initial issue here? I came across the same
thing
but I do not have any joins in the feature source.
Here is the javascript that I have to update the selection. 

                    var selectionXml =
document.getElementById("ctl00_ContentPlaceHolder1_hfSelectXml").getAttr
ibute("value");
                    var mapFrame =
document.getElementById("viewerFrame").contentWindow.GetMapFrame();

                    mapFrame.SetSelectionXML(selectionXml);
                    mapFrame.Refresh(); 

the status bar shows 1 feature selected but no feature is highlighted. I
also tried manual refresh of the map(from context menu) that did not
highlight the selected features either. Appreciate any help.
Thanks.
