Embedding multiple issue collectors version

[Cristina_Abunei]

Hello,

I'm trying to use multiple issue collectors on the same page in confluence and I'm trying to use this documentation for "Embedding multiple issue collectors": https://confluence.atlassian.com/adminjiraserver073/advanced-use-of-the-jira-issue-collector-861253497.html?_ga=2.171918176.1948679480.1505720674-229346078.1475408468#AdvancedUseoftheJIRAIssueCollector-FullSourceCode

I tried and is not working.

My question is in what version of issue collectors is working this solution? because i'm using  2.0.14 and that example is for 1.2. 

Thank you!
