GWT-RPC: encodedRequest cannot be empty error

[kishorpatel415]

Hello,

We are using GWT 2.3 in our web application. In our log files we see the error "encodedRequest cannot be empty". This error occurs when we make GWT-RPC calls. The error is intermittent. It does not happen all of the time. Based on the log file data, it happens approx 5% of the time for GWT-RPC calls.

Any work arounds for resolving this? Thanks.
