Issue with FileUpload UI element in WDA

I have a problem when trying to use the ‘FileUpload’ UI element in Web Dynpro ABAP.  I get the below error when trying to upload any file:

Error when Uploading; the file name is invalid or the file is too large.

I researched about this and found that this is a problem with the standard SAP UI element and was directed to the note ‘0001736212.  According to this, we need to have support packs ‘SAPKB73105’ and  ‘SAPKB73106’ to rectify this error.  We are not in a position to upgrade our system since we are about to go live and it's a risk to the entire project.

Now the question is, is there any other alternative solution I can use to upload the files from the WebDynrpo application with out using the standard WebDynpro File Upload UI element.

Thanks
