ClassCastException on call to DSRequest.getSortBy() in custom DataSource

[ispringer]

I'm using a recent snapshot build of SmartGWT. When I try to call getSortBy() on the DSRequest object passed in to my GWT-RPC (i.e. ClientCustom) DataSource's transformRequest() method, I get the following ClassCastException:

Note:

String sortBy = request.getAttribute("sortBy");

works fine.

but:

SortSpecifier[] sortSpecifiers = request.getSortBy();

causes the above exception.

This was fixed only a few days ago. Pick up the latest nightly.
