FileDownload implementation not working



I am trying to implement a file control which is not working. I have done the following.

I have mapped the data attribute to a context node of type binary.

The content of the file is String array. I have converted the contents to byte and assigned it to data node. But I think the data node should not be assigned the content it is a place holder for the data while downloading. So I have tried by assigning data as well as without it.

And following mappping has been done in code

IWDModifiableBinaryType binaryTypeDownload;

IWDAttributeInfo attInfo = wdContext.nodeConfigFiles().getNodeInfo().getAttribute("DownloadData");

ISimpleTypeModifiable type1 = attInfo.getModifiableSimpleType();

binaryTypeDownload = (IWDModifiableBinaryType) type1;

binaryTypeDownload.setMimeType(new WDWebResourceType(type,"",false));


It gives me this exception : MappedAttributeInfo(DetailsView.Device1.ConfigFiles.DownloadData): must not modify the datatype of a mapped attribute

Please help.
