#606 Can't make in preview

[Jonathan Dushoff]

Preview operations on the page http://lalashan.mcmaster.ca/theobio/circumcision/index.php/FGC/recode repeatably and unalterably produce PE internal errors (something about invalid URI).

[Lee Worden]

Presumably a side effect of [#605]. Looking into it.

[Lee Worden]

Turns out: not a side effect of [#605] at all! Just a coincidence.

This error comes about because this page uses project FGC, with project FGC (itself) registered as a do-not-copy prerequisite. That is not supported. But rather than failing obscurely, it should probably just override the prerequisite's do-not-copy attribute with the focal project's implicit do-copy attribute. Or maybe it should generate a warning? Will work on.

That is not supported.

I should say, it is supported as far as registering your project as a prerequisite of itself, which is a nice workaround way to give it a variable name; but you can't make the focal project do-not-copy.

Done

Or maybe it should generate a warning?

Leaving ticket open pending discussion of this crucial question, and possible objections to

you can't make the focal project do-not-copy.
