user macro resolution order

When I put a {userMacro} inside a [link to {userMacro}] it doesn t get resolved at the right time. Confluence wants to create a page, though the link exists.

Solution?
Thx

I would suggest you modify the userMacro in question to just generate the link rather then the page name.

Thanks, I did just this, but isn t the resolution order violation a major bug?

Hi Guenter,

I'm not so sure this is a bug, major or minor. The output from a user macro could be anything, not just text. I guess Confluence is playing it safe and saying that a text string is expected between [ and ], hence it doesn't parse the contents for any user macro processing.

Well, thanks, my opinion is that expressions should be parsed in the right order, no matter what - and they could throw an error still if it evaluates to something the browser can t handle.

The currents behavior fits well with Confluence s other inconsistencies.

@Guenter - if you feel strongly, I suggest you raise a well-worded ticket here, https://jira.atlassian.com and make your case for the Atlassian team to address. If feasible and highly desired they usually will deliver.

@Guenter - I would also be interested to know what version of Confluence you are using.

Good idea, Daniel!
5.1.3, so I need to re-test how much this applies to a version > 4. We were at 3.5.9 until recently.

Just tested this quickly and saw that a Link > Advanced [link to {userMacro}] renders an internal server error.

Needa rethink the whole dynamic link thing.
Thanks

As I couldn t find a way to put a macro inside a link I had to code the whole thing as XHTML:

## @noparams
#set($len1 = $space.key.length() - 2)
#set($len2 = $space.key.length() - 1)
#set($sub0 = $space.Key.substring($len2))
#set($sub1 = $space.Key.substring($len1, $len2))
#set($sub2 = $space.Key.substring($len1, $len2))
#set($sub3 = $space.Key.substring($len2))
<ac:link> <ri:page ri:content-title="page title part 1 #if ($sub0 == "0")$sub1#else$sub2.$sub3#end page title part 2" ri:space-key="SPACEKEY"/> </ac:link>

As I got no answer to the https://answers.atlassian.com/questions/205782/velocity-expression-as-argument/205824 I had to put the argument expressions into variables.
