Re: RequestFactory Could not parse payload: payload[0] = N

I ran into the same problem. With a bit of debugging I found out that I was trying to send NaN in one of my Float attributes to the GWT Client.

If you have a test case to reproduce that issue, you can provide it to that issue on google app engine: https://code.google.com/p/googleappengine/issues/detail?id=8471

I should have thought of that, sorry. Unfortunately (fortunately for me), I don't see the error anymore. Lots of things changed in the mean time (source code and db schema) as this project is under heavy development. Yes, I could go back-trace using my repository and maybe make it fail again, but time is a scarce commodity, so I choose to continue development.

I did notice one anomaly the day it happened, not sure it's related to the issue; I had a copy of a src directory under my WEB-INF folder, (I blame eclipse, but who knows, could have been user-error; me), which I deleted. I'll make sure to capture the payload if I see this again.

Would be great if any of you could log the request payload when this error happens.

In the mean time, we might want to modify the RequestFactoryServlet to log the payload when there's an unrecoverable error, in addition to the exception.

Could you please open an issue? (if there's none already)

Just saw this error myself as well, slightly different message:

Unexpected error: java.lang.RuntimeException: Could not parse payload: payload[0] = I

using GWT 2.5 and no GAE. Stacktrace is exactly the same though. Don't know why or what it means, just that I get it so far when a specific request is made. Has anybody found out what this means?

Hey Sydney, I've been seeing the same error message recently. Did you figure it out?

Any idea of what the exception means? Thanks
