I would do something like this. Hope this help.
theControl.events.register("getfeatureinfo", this, showInfo);
function showInfo(evt)
{
if( evt.text != "\n" && evt.text != "")
map.addPopup(......);
}

[OpenLayers-Users] WMSGetFeatureInfo hangs when getfeatureinfo returns no
results
Hi,
I am using openlayers 2.9 together with mapsever 5.6. I am retrieving
queries with OL control WMSGetFeatureInfo() and getfeatureinfo event. Up
to this point everything works fine, being able to show query results when
the user clicks on a queryable map feature. However if the user clicks the
map on a zone where no features are available, the mouse cursor moves to
the loading state (hourglass icon), and waits for a response that doesn?t
seem to arrive. The mapserver logs show that no result was returned (?
GetFeatureInfo Results: Search returned no results). However, it seems
that OL is not able to handle this response and remains waiting in this
state until the user performs another operation.
Any suggestions about how behaviour could be fixed? Shouldn?t OL handle
the no result exception case?
Thanks in advance,
Manuel
