Exception on FileUpload

[Former Member]

Hi, I am trying to upload a file using the tutorial https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/00062266-3aa9-2910-d485-f1088c3a... and I get the following exception when I select a file and press the upload button. It doesn't even hit my Action method.

I have attached "resource" property of the UIFileUpload control to the type com.sap.ide.webdynpro.uielementdefinitions.Resource. And not binding "data" or "fileName" property to anything as they are obsolete.

Very very strange and bad. Figured out what it was so posting for others. If the Resource context variable is inside a node then this error occurs. If its at the root level then it works fine. Its a bug in Web dynpro. Wasted 2-3 days on this stupid thing. Using Netweaver 7.0 sp11.

Hallo Faraz,

are you sure, that your context node is correctly initialized with a node element? You mentioned, that it works with a toplevel context attribute of type resource but not with an attribute in a toplevel context node. Make sure, that the toplevel context node is of cardinality 1..1 and that 'initializeLeadSelection' is set to true. Binding a FileUpload UI element to a multiple context node of cardinality 0..n or 1..n only make sense in a table scenario. In a simple form scenario the form is normally bound to a node with only one node element inside.

In case these recommendations do not yield any success please report a CSS message on this issue.
