In our ADF application we use the af:inputFile to upload documents/files into our application.
The end users often use it from Outlook to attachment an email to an 'order'.
They do a drag and drop from Outlook to the browser and drop the file on the inputFile component.
By default this wasn't possible in the past, you can't drag & drop an email from Outlook but with a thirdparty component it is possible.
Since Chrome 76 this changed, now you can drag & drop an email into the ADF af:inputFile without any external software being installed.
This however causes the email to be deleted from Outlook.
So the current situation:
- drag and drop from Outlook to Firefox --> doesn't work
- drag and drop from Outlook to Chrome -> it does work but the email is deleted
- drag and drop from Outlook to Edge -> it does work and the email is still available inside Outlook.
We of course don't want the email to be deleted and like to correct this behaviour.
I found the following article which describes the same issue: https://answers.microsoft.com/en-us/msoffice/forum/all/drag-and-drop-works-however-deletes-email-can-we/865f60c3-7980-4465-8a19-4d60b0ae5aba?page=1
It seems that multiple 'dropEffects' exist, 'move' and 'copy'.
I assume the following.
- Chrome deletes the mail when 'move'
- Chrome will keep the mail when 'copy'
- Edge ignores 'move' and 'copy'.
Inside the article there is a suggestion to change the dropEffect (and an example) but I've no idea how to do this inside ADF or at least I can't find it.
I also tried to look at the generated html source code to check if I could fine something similar to 'dropEffect' but I wasn't able to find anything.
The code:
As you can see the af:inputFile is quite simple and standard within ADF.
Does anyone have a suggestion/idea how to change the dropEffect for the af:inputFile? I would like to try and put it to 'copy' to see the effect.
