I've been looking at this problem for just about a day straight now, and just can't see why I'm getting an out of bounds error on send. I've tried updated to the latest Gumbo nightly (9377), which no luck.
My code to launch the WebService call looks like this: _calibrationData = new ByteArray(); var stream:FileStream = new FileStream(); stream.open(file, FileMode.READ); stream.readBytes(_calibrationData, 0, stream.bytesAvailable); var token:AsyncToken = this._service.mLoadCalibration(file.name, _calibrationData); token.addResponder(this._mLoadCalibrationResponder); Which seems to be a-okay. Or, am I missing something obvious? I'm pretty sure I've hit up against a SDK bug. I've opened a bug report with Adobe, to track this issue at http://bugs.adobe.com/jira/browse/SDK-22751 Anyone else transferring "large" (1MB) base64 encoded data using the Flex webservice client? Any feedback highly welcome! Thanks, Mike
