Hello,

I am testing sao client with an application. One form of my app have a binary field with image widget.

When I want to upload a file biggest than 100Kb and try to save the registry, sao show "processing..." message indefinitely.

When I upload a file smallest than 100Kb this work.

I am using version 3.8 on Archlinux.

Grettings...

I think you should report an bug.
I suspect a limitation on the size for Blob or createObjectURL creation.
Please check the browser log if there is no error message and include it
on the bug report (usually when "processing..." stays is because an
exception was raised at an unexpected place).

About this topic...

BIG_IMAGE_SIZE value is set to Math.pow(10, 6) -> 1MB

however apparently the error is that the comparison
if (value > Sao.common.BIG_IMAGE_SIZE) is true

although my image size is 482kB.

I test changing BIG_IMAGE_SIZE to Math.pow(10, 7) and works.
But I when I return BIG_IMAGE_SIZE to original value Math.pow(10, 6) now also works...

Did you get this by using a debugger?
What was the value of 'value'?

This is very strange. Unreproducible bugs are most of the time
impossible to fix.

To reproduce the error, I am using:
Trytond 3.8.0
Sao from hg -> commit: 9635. The last commit at time
Chromium 47.0.2526.80

I debug the code and see that the problem is on call to function String.fromCharCode.apply(null, value) on tryton-sao.js:676 inside Sao.rpc.prepareObject.
I found this info concerning:
https://github.com/michael/github/issues/137
https://github.com/mathiasbynens/String.fromCodePoint/issues/1

I can confirm that Firefox dont produce this error.

Regards.
