How to access a page property via macro

[Adolfo Casari]

I need to access a page property via a (user) macro.

Is this possible?

Is this what you are looking for?

#set ($containerManagerClass=$content.class.forName('com.atlassian.spring.container.ContainerManager'))
#set ($getInstanceMethod=$containerManagerClass.getDeclaredMethod('getInstance',null))
#set ($containerManager=$getInstanceMethod.invoke(null,null))
#set ($containerContext=$containerManager.containerContext)
#set ($contentPropertyManager=$containerContext.getComponent('contentPropertyManager'))
 
$contentPropertyManager.setStringProperty($content, "myProperty", "Stuff")
$contentPropertyManager.getStringProperty($content, "myProperty")

Thanks. myProperty would be set according to https://confluence.atlassian.com/display/DOC/Page+Properties+Macro (like Deadline in the example in that page), right?

Ah ... got it. You are looking for how to access values within a page properties macro. Not sure you could do it with a user macro. Mainly it is for paring with the page properties report macro.

[Adolfo Casari]

$content is a reference to the current page objet? Your code showed me how to move forward. In my scenario myProperty is a JIRA issueId associated with a page that display info about that issue.

Adolfo did you succeed in retreiving page properties in a User macro ?

[Adolfo Casari]

Yes.

@Adolfo: I also want to display values located in the page properties macro of the current page. Would you mind posting a code snippet of your successful approach here? i take it that Davin pointed you in the right direction but you had to develop the final thing? I would be very interested in what you ended up with. Thanks in Advance

[Adolfo Casari]

You just need the last two lines of the snippet above. The first one to set a property and the second to read it.

Thanks for the information. i tried it but didnt get any results regarding access to values inside the page properties macro on the same page (i assume that is what you originally asked about?) I guess i need to ask that specific question on my own, huh? :-) Thanks anyway!

[Adolfo Casari]

That snippet is not for set/get Page Properties macro values, it's for your own values than can be set with a user macro and read within another. I used it to set a JIRA issueid to a confluence page and then use that issueid to query jira with a jiraissue macro.

Thanks David, this worked for me.

Sorry for the newbie question, how would I integrate this, I seem to have the option of a user macro, a macro plugin or a full blown macro.

I have documents with a page property block with things like version and document number.

I want to have the document number and version in a footer.

It would seem a generic macro that just takes one parameter, the name of the property would do.

  $contentPropertyManager.getStringProperty($content, parameter1)

I need to can the solution and pass it to general purpose IT department to install.

BTW: Am I missing the point, this is such an obvious thing to want to do, is it built in and I missed it?
