Album with all numeric name won't display
I use [[*pagetitle]] in my Gallery snippet call to specify the album I want. I create an album with the same title as the page I want it to be seen from. (It's a real estate site: each property has it's own little gallery of images, and it helps keep control to have page and album with the same unique name).
Some of the properties have numeric-only references, others have alphanumeric references. The pagetitle is where the reference data is stored.
Given the way I arrange that album name and pagetitle are the same, I can't determine whether it's a Gallery Album name limitation, or the unholy combination that is causing the grief.
If the pagetitle/album name is alphanumeric, it doesn't matter whether it is alpha first or alpha last - it works. If all numeric the snippet is apparently ignored. No trace of it on the rendered page.
