Can the Greenhopper rank by manipulated in scripts via an API?

[Rick Trudeau]

We have Jira 4.3.4 running GreenHopper 5.6.8. We are using the GH Rank property to assign ranks to the issues in our sytem.

In our setup, I would like to be able to modify the GreenHopper Rank of an issue based on the rank value that is assigned to a different issue.

For example, as a side effect of changing the Rank on Issue#1 to 100, I would like to have Issue#2's rank changed to 101.

I have been looking through the API and have found a way to read the GH Rank using the Groovy script getCustomField function.

What I see in the returned rank value is not the absolute value of the Rank as seen in the GUI, but some very large number. I don't want to attempt to set the rank value because I'm not sure what relative value should be used.

So, my questions are:

1) Does anyone know how to translate the rank DB value to the value seen in the GUI?

2) Is there a better API for retrieving the Rank value?

3) Is there an API that allows us to modify the Rank value?

You can indeed ust the REST API internally to a JIRA plugin to do this but the more direct route is via the RankService. I posted some sample code for this in this answer.

You can use the REST api of GH to do this. Read https://answers.atlassian.com/questions/45323/rest-api-for-ranking

If you are developing a JIRA plugin, you will have to invoke the rest method from a javascript to do it.
