Perspective FileUpload component onFileRecieved event script issue

[Haniyeh_Seyed_Alinez]

Hi everyone,

In my Perspective project, I used two FileUpload components, each running a script onFileReceived. My issue with both FileUpload components is that when a file is uploaded, the script associated with the onFileReceived event is executed twice. I tested same scripts on other components' event actions and there was no issue. I guess it could be something related to Perspective's FileUpload component. The version of Ignition I am using is 8.1.32.

Any idea about this is appreciated.
Thanks

The problem was fixed in version 8.1.36.

If you can't update versions, this post has some workarounds:

Upload component gets file Received Script triggered twice

I ran into that issue myself a while back, and came up with this workaround: def runAction(self, event): import java.lang.Exception from threading import Timer # Fixes a bug in Ignition that causes this event to fire twice in a row... def setOkayToUpload(self): self.custom.okayToUpload = True if self.custom.okayToUpload: self.custom.okayToUpload = False ...(process upload)... Timer(0.5, setOkayToUpload, [self]).start()

Thanks for your response. As I cannot update the ignition version running on the server, I resolved this issue based on the post you provided. Here is the link to the workaround I used:
