How to set resolution in a jira issue using SOAP API?

[Bharadwaj Jannu]

Hi, We are SOAP API to set the resolution to Unresolved. I tried the snippet

RemoteFieldValue[] actionParams = new RemoteFieldValue[] { new RemoteFieldValue("resolution",
new String[]{null}) };

RemoteIssue updatedIssue = jiraSoapService.updateIssue(authToken, issueKey, actionParams);

But the issue's resolution not clearing to Unresolved.

Can you help where I went wrong.

As soap is deprecated and unused in later versions, my memory of it is failing.  Part of me wants to suggest using a blank string instead of "null", and also the resolution value is not an array, it's a single value.

However, Resolution should not be on an Edit screen either, and SOAP should not be able to edit it if it's not.  I suspect you need to trigger a workflow transition instead, one with "clear resolution" set on it.
