@arporter @sergisiso This is ready for a look.

[arporter]

Thanks for tackling this so quickly Aidan. I think it's OK but it would help to see what the generated code looks like in the test too. I'll run the ITs next time around.

[LonelyCat124]

@arporter ready for another look. Also added where test in here but it just worked correctly so no code changes to support it.

[arporter]

Looking good, thanks Aidan.
Just a bit of tidying to do.
I've fired off the ITs just now.

[LonelyCat124]

@arporter I think I fixed all this, ready for another look.

[LonelyCat124]

Martin has some other cases so I'll try to check that too before we merge this.
Edit: that was covered by #3350

[arporter]

Thanks Aidan, pretty much done now. There's just one test that I think should be split into two and then this is good to go.

[LonelyCat124]

@arporter Fixed, added the missing test declaration back in, sorry for that.

[schreiberx]

Thanks a lot for this update! It fixes my problem.

[arporter]

Thanks Aidan, all good now. ITs were all green.
@schreiberx is happy and I will proceed to merge :-)

[schreiberx]

Thanks a lot :-)
