Upload with Direct action


  • Subject: Upload with Direct action

Hello folks

We are using a plug-in to upload the file contents to Webserver. The file
information will be submitted to a direct action method. There is an
independent Form along with the plug-in.

As we all know WO 5.2 has many changes to the upload component, somehow the
communication between the upload plug-in and server is broken.

I browsed through the Release notes of WO 5.2 and 5.2.1.

The file contents are the last item to be uploaded. Direct action method
fetches the form values in the order of submission. In spite of this, the
request is blocked at the form value parsing routine.

The exception looks similar to Apple Reference: 3181505 in WO 5.2.1 release
notes.

Mac OS 10.2.4
WO 5.2.1
December Developer Tools
FrontBase 3.19

Please let me know the possible problem.

Thank you.

Regards

Suhas
