Started to look into ERAttachment and found this to be more or less what I
need. Trying to implement things however don't go well. I want to use
ERDragAndDropUpload component from ERAttachment but somehow the data is not
properly transferred.
Here is the bindings:
Uploader : ERDragAndDropUpload {
attachment = currentERAttachment;
action = uploadAction;
completeAllFunction = finishedFunctionName;
configurationName = "UserAttachment.attachment";
editingContext = patient.editingContext;
storageType = "file";
includeFileSelector = true;
}
Everything seems to work but no data is available. When I set a breakpoint at
ERDragAndDropUpload.takeValuesFromRequest I observe the following:
public void takeValuesFromRequest(WORequest request, WOContext context)
{
NSData data = (NSData) request.formValueForKey(dropTargetID());
if(data != null) {
// this is always null
Adding a line to access the request contents I get (see screenshot)
_bytes == 0 ???, however _streamLength seems reasonable (uploading a 5.3 MB
PDF). When I try to dump all formValueKeys (using the formValueKeyEnumerator
from the request) I get nothing and so formValueForKey(dropTagetID()) returns
null. I tried to stream the contents() to a file with
rawData.writeToStream(aFileOutputStream) just to get at the data somehow, but
the resulting file is of length 0.
What am I missing?
Thanks a lot
