Include children macros

[Jamil Rahimov]

Currently I'm using Include children macros. (This macros indicates all children of another page on current page)

//---------------------------------------------------------------------------------------------------

For example as you can see there is other articles page and it has children:

//------------------------------------------------------------------------------------------------

I showed children page of Other articles on another page

But there is latency problem when I want open page it opens very late.
What can I do for resolve this problem?

User macros code:

## Categories: Confluence content

Hi guys, you need  add the below to the setenv.sh:

CATALINA_OPTS="Dmacro.required.velocity.context.keys=pageManager,spaceManager,attachmentManager,permissionHelper,userAccessor,i8n,dateFormatter,res,settingsManager,htmlUtil,generalUtil,bootstrap,containerContext,action,req,content ${CATALINA_OPTS}"

its help for me.

Best regards Aleksey.

Hi Aleksey, many THANKS it DID help !!! (one little mistake "-" char is missing before Dmacro, -Dmacro etc. is correct)

Here is some info about the reason: https://developer.atlassian.com/server/confluence/confluence-objects-accessible-from-velocity/

In Confluence 7.13 LTS (7.13.15), Confluence 7.19 LTS (7.19.7), Confluence 8.2 (8.2.0) and later versions, the user macro Velocity context is set to include only the generalUtil and bootstrap variables. To change or add more variables, you will need to configure the system property macro.required.velocity.context.keys. See configuring system properties to learn how.

Hello Jamil,

Thank you for raising this with us.

How long would you say it takes the Children Display Macro to load? How many children are there? If there are too many, it can cause performance issues when loading the descendants. If you try reducing the number of children pages that load, does the load time reduce? 

Lastly, I see you shared a user macro code, can you let me know what that is for and what you're trying to do with that?

Regards,

Shannon

@Shannon S 
My task is showing all children in one page to make it easier for users.
They want see all documents in one page rather than separately.
Yes depending on count of pages it reduces the performance.
Number of children can be different.
I need optimize system or this macros for realizing better performance regardless of number of pages.(If it is possible)

Hi Jamil,

My apologies; I hadn't seen your response to what the code was that you included, but it just occurred to me that you are not having an issue with the Confluence Children Display Macro, but with a User Macro called Include Children. I'm not familiar with that User Macro, but it looks like it originates from this Bitbucket repository.

I would recommend trying to use the built-in Children Display macro instead to see if that helps you accomplish the same thing, otherwise you might need to see if you can get in touch with the original creator of that User Macro.

Regards,

Shannon

Hello, after updating to 8.3.0, the macros  stopped working.

[Martin Hudak]

The same here, after update to 8.3.0 it does not work anymore :( .
