[mapguide-users] [MapGuide 2.4] Web .Net API SetResource failed 1 to 2 times

[Rémy Gourrat]

Hello,

I have a .net web api  wich edit feature source definition

At the end of the function, I update the new feature source definition by this code in the session repository

"...
// Chargement du String xml dans une variable type MgByteSource
                               MgByteSource contentByteSource = new MgByteSource(encodedDefinition, encodedDefinition.Length);

                               //Ecriture du nouveau FeatureSourceID dans la Session: en lieu et place du précédent s'appuyant sur Library
                               String str_NewFeatureSourceId = FeatureSourceListElem.Replace("Library:","Session:" + sessionId);
                               MgResourceIdentifier new_MgfeatureSourceId = new MgResourceIdentifier(str_NewFeatureSourceId);

                               // Sauvegarde de la ressource avec la nouvelle définition
                               ag_ResourceService.SetResource(new_MgfeatureSourceId, contentByteSource.GetReader(), null);

...
"
During many hours it's running very very  well

And suddenly it's failing, and after few minutes or hours or enable the iis trace it's running well again !

But when it failed, my Exception Catch code is not executing in my function

"
                catch (MgException mge)
                {
                               errMsg = mge.GetExceptionMessage() + "\n" + mge.GetDetails();
                               ag_PrintMessage("ag_proc.aspx : " +  "ag_SetSRSFeatureSource : ","Erreur ! Exception levée par Catch " + errMsg);
                }
"

But I have a message in the Errors.log :
"

Somebody have an explanation for this ? is there a specific concept that I don't understand ?

Thanks
