As of 3.0, the dfdl:fillByte is now required for all elements, even if it may not be used. We had a bug where we didn't require the property even though there were cases where it was needed. Because we didn't require it, we didn't know it was missing until runtime which lead to an exception. Rather than trying to figure out exactly when it is and isn't needed at schema compile time, it's easiest to just always require it where it *might* be needed.
The easiest way to add this is to just specified it once in the dfdl:format tag so it is applied globally. Which is what you have. But when I try to compile your schema, I get a different error: Schema Definition Error: For fillByte, the string ( ) must not contain any whitespace. Use DFDL Entities for whitespace characters. So the issue here is that you cannot use a space character to specify a space fillByte. Instead you need to use a DFDL entity, e.g. fillByte="%SP;" On 12/11/20 11:06 AM, Roger L Costello wrote: > Hi Folks, > > I installed the latest version of Daffodil (3.0). > > My DFDL schema worked with previous versions of Daffodil, but now it doesn’t > work … > > My DFDL schema is below.
