comment Unexpected behavior when using SortBy as a dataset filter
@Rojo "Yes" on both points. Query always treats its parameters as operators, so it is not receiving special treatment when inside another query. I'll leave it in the quoted extract since that it how it appears in the documentation.

comment Dataset: cannot reproduce a basic example. A bug?
@PatoCriollo I followed those exact steps and they work for me. I even tried it with no init.m. Hopefully the next time the problem occurs for me it won't be in the middle of real work and I can take some time to diagnose.

@PatoCriollo FYI, I couldn't find a way to make that expression fail on my machine.

comment Dataset: cannot reproduce a basic example. A bug?
I experience this problem intermittently, but have not yet been able to determine reproduction steps. At some point in my session, this error begins to appear in all typeset Datasets, even the examples from the help. In my case, a kernel restart usually corrects the condition. V10.0.0 / Win7 / 64-bit
