Re: Getting a collection created from 4D function to work in Storage.
The first line does nothing because you don't do anything with the function result of the call. The second line assigning $myTempVolumeCol to a copy returns a regular collection (see documentation). The error is because you can't assign a regular collection to a shared collection (Storage.serverVolumes:=$myTempVolumeCol). To duplicate an object or collection as a shared object/collection you have to iterate over all of the values and then recursively convert to shared any object/collection.

Getting a collection created from 4D function to work in Storage.
I am having a curious time with this one. I am trying to get a collection retrieved from Get System Info to be saved into the Storage Collection. Right now I am using the following to get the information. $systemInfo:=Get system info $volumeCollections:= $systemInfo.volumes This is saved in a table in 4D on the server and then retrieved at the Client machine. On the client a collection shows up as $volumeData another collection. New shared collection($myTempVolumeCol) $myTempVolumeCol:=$volumeData.copy() Use (Storage) Storage.serverVolumes:=New shared collection Use (Storage.serverVolumes) Storage.serverVolumes:=$myTempVolumeCol End use End use This code gives me the following error. “Not supported value type in a shared object or a shared collection” This seems to be preventing me from using the Storage. I can just assign the variable as an interprocess variable but I was trying to get away from using interprocess variables. Any suggestions? I have also tried the following to get the data into a shared collection prior to trying to copy to Storage. The attempt to copy will also fail. COLLECTION TO ARRAY($volumeData;$volumeArray) myTempVolumeCol:=New shared collection Use (myTempVolumeCol) ARRAY TO COLLECTION(myTempVolumeCol;$volumeArray) End use <>serverVolumeData:=$volumeData.copy() Use (Storage) Storage.serverVolumes:=New shared collection Use (Storage.serverVolumes) Storage.serverVolumes:=myTempVolumeCol End use End use C_COLLECTION($mySavedVolumes) $mySavedVolumes:=Storage.serverVolumes The array to collection will give me a collection of null values. Is this a case of 4D just not having fixed this yet. I should be able to copy a return vale object to Storage or I would expect so. ** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **
