Signatures for the "onBeforeAjax" event do not match.
ajax
callEvent("onBeforeAjax", [mode, url, params, x, headers, null, defer])
Uploader
callEvent("onBeforeAjax", ["POST", url, details, xhr, headers, formData])

Hey @lBeJIuk, the passed in parameters do match from what I can see. If we go by the article that you yourself linked, we can see that the parameters seem to match:
This is different simply because in the case of uploader we are actually sending the data (files argument = formData), whereas in the other cases we are not.
@Dzmitry Yeah, that's right. But in the case of Uploader, "promise" is not sent.
You are correct, this is the intended behaviour, as the file uploading process isn't the same as sending a standart
webix.ajax
request and doesn't use the promise API, which is why it is not being sent.Is there any particular reason why this is an issue in your case? As far as I'm aware, you can make a use of the uploader events and cover most of the use cases.
Or, perhaps, you want this to be reflected somewhere in the documentation, and you were pointing out the inconsistency?
@Dzmitry
I use "onBeforeAjax" to make a global response interceptor.
Something like that:
And when trying to use Uploader, it was found that the event was called with other parameters.
