[OpenLayers-Users] WMSGetFeatureInfo hangs when getfeatureinfo returns no results

[Manuel Aymerich]

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
