How to automatically assign a number to a page?

Question

I am building a knowledgebase and each article has its own distinct number. The format is K-0000. There is a requirement from our stakeholders that this number be automatically assigned so our authors don't accidentally assign the same number to multiple kb articles. This number appears in the title and in a table at the top of the article.

Any idea how to accomplish this in Confluence 4.0?

Thank you!

Ok, I see... Thus you might probably want to develop your custom plugin and got the autonumber for pages from a kinda global variable (thread safe, singleton, etc)...

We already have 850 articles and people know and refer to them by their number. I don't want to change them now, and I don't want to change the numbering convention...or have gaps in the number if the page ids were used for other spaces.

Why don't you want to use PageID for that?

In admin area go to Edit Site Layouts » Page Layout and change page layout in a way that it will show somewhere "K-<Page ID>" page id I guess can be obtain through a helper variable (not sure), need to read some documentation.
