Could you explain what this has to do with Atlassian applications?

Yes sure I was looking for community help of WSO2 BPS app in this page:

https://docs.wso2.com/display/BPS360/BPMN+Samples

When I click "Online Help" it redirects to atlassian community.

I would like a sample using dates in BPS. If you try my code above will may understand the error.

I am sorry to say that you have landed in the wrong place.

The documentation you are reading is being hosted in "Confluence", which is an Atlassian product.  You have looked for help within your software community, but landed on the help link for Confluence, not one for your community.

The Atlassian community likes to help, but we can only really help with Atlassian stuff.  If your problem was with Confluence, you would get loads of help.  But it is with software than just uses Confluence for its documentation, so  I'm afraid you are looking in the wrong place.

OK :) you can delete this fórum if is possible. Thanks anyway
