AUTOINC is resolved in Foswiki::UI::Save, but not in Meta. So when you want to create a topic using Foswiki::Func::saveTopic, AUTOINC will not be resolved.

This code should be implemented in Meta.

-- ArthurClemens - 02 Jan 2011

This also applies to the edit script; POSTing to an edit script with a topic named with AUTOINC0 will not expand properly (it literally creates, Eg. TestTopicAUTOINC0 instead of TestTopic1234).

-- PaulAlexander - 02 Mar 2012

should implement this for 1.2.0 -
  1. move the AUTOINC processing to Meta,
  2. fix the corner case Paul found - I've seen a few instances where we have non-expanded AUTOINC's saved too

-- SvenDowideit - 08 Mar 2012

It would be great to fix this so it works for all saves.

Now for edit scripts, I see a risk in making this possible. Isn't this function deliberately left in save? IIRC the number is generated simply by globbing the topics in the directory that match the AUTOINC pattern, then find the last entry, add one to the number found and create a new topic name. This ensures at save-time a unique new topic name which is actually used.

If moved to edit (to handles Paul's case), does that not mean the generated topic name will not necessarily be saved. More importantly, an edit screen can be open for some time, other users could initiate a new topic in a similar manner and be given the same topic name to create. I suppose the globbing could include picking up leases as well as txt files to prevent this. OTOH this would potentially create gaps in the sequence if the user cancels the edit session, which may not be desirable.

-- JulianLevens - 08 Mar 2012

Good point. I thought making AUTOINC consider lease files would be enough, but perhaps we should encourage people to post to save first, then redirectto the edit screen.

On the other hand... allowing the save method to stomp on topic with an active lease could be considered a bug.

If users really care about contiguous numbering, they should be use the save + redirectto -> edit; those who don't care, could simply go straight to an AUTOINC edit. Are there any holes in that?

-- PaulHarvey - 08 Mar 2012

No that covers it, as long as the user understands the options they have available. It's their party or funeral.

-- JulianLevens - 08 Mar 2012

Defer to 2.0.

-- GeorgeClark - 02 Jun 2014

Will be fixed in Foswiki 2.2.
