Description

I upgrade my project from grails 1.0.3 to 1.0.4, but it failed in uploading files. I have to revert back to 1.0.3.
The bug can be reproduced as follow:

gsp:
Upload Form: <br/>
<g:form method="post" enctype="multipart/form-data">
<input type="file" name="file"/>
<input type="submit"/>
</g:form>

controller:
def index = {
if (!params.file) return

def f=request.getFile('file')
if (!f.empty)

{ f.transferTo(new File("d:\\tmp\\a.jpg")) render 'transfer ok' }

else

{ render 'null file' }

}

This controller sometimes returns 'transfer ok', but if you try more times, it throws exception:
Error 200: java.lang.IllegalStateException: File has already been moved - cannot be transferred again
Servlet: grails
URI: /testuf/grails/uploader/index.dispatch
Exception Message: File has already been moved - cannot be transferred again
Caused by: java.lang.IllegalStateException: File has already been moved - cannot be transferred again
Class: UploaderController

In fact, the controller call transferTo() only once. Why the file is moved?

If I start a new browser, sometimes the controller throws another exception:

[1149703] errors.GrailsExceptionResolver
java.lang.NullPointerException
at java.net.URLDecoder.decode(URLDecoder.java:119)

The test app is added.
I run the app with "grails run-app", and then try to upload files, the bug reproduced.

Probably another manifestation of the bug related to multipart forms, that I already reported and is now fixed.
