Max file size

[edulid]

I am trying to set a max upload file setting server.properties with: fileUpload.maxFileSize: 10485760 as shown here: https://www.smartclient.com/smartgwt...cs/Upload.html

When I try to save a larger file, I get this exception:

=== 2016-05-04 10:41:46,175 [ec-3] WARN  RPCManager - Transaction 26 aborted.  Caused by:

Which seems correct.
But the answer never returns to the client! The client keeps waiting until a timeout. And when I check the RPC tab, the update never returns, as I expected because of the timeout.
So how to tell the client that the size exceeded ?

Using smartgwt 6.0-p20160408 power

Set dataSourceField.maxFileSize. The property you're using sets a maximum across all uploads anywhere in the system, so it's really for DDOS defense. Exceeding field.maxFileSize will lead to a normal validation error, and enforcement will actually happen before the browser uploads the file at all (in browsers where that's possible).

Thank you, this worked.
Shouldn't this appear in the link I posted? I think this info is missing there
