Workflow Post Function - If Original Estimate is 0m, clear the field by setting Original Estimate to NULL

[Sean Hayes]

If the Original Estimate of an issue is 0m, any time written to it will set the Work Ratio to 9223372036854775807%

To correct this, I used a post function on my Workflow Transitions to conditionally clear the Original Estimate and Remaining Estimate fields, only if the original estimate is 0m:

if( 0 == issue.getOriginalEstimate()){
    issue.setOriginalEstimate(null)
    issue.setEstimate(null)
}

Is there a better approach?

This should work for you without any custom scripting:

Still use a Post Function, use Update Issue Field, select "Remaining Estimate", leave Field Value blank, hit Update.

You can do the same for Original Estimate if you wish.
