ScriptRunner script "Cannot find matching method"

[Aaron Andrade]

I wrote a script Post-Function [ScriptRunner] in a transition to set a field "Commission Date" to today's date if the field is empty.  I'm getting errors, but I'm obviously missing something.   I 'think' the types and methods are declared correctly.

Thanks in advance for your help!

getCustomFieldValue() expects you to pass in a singular custom field object. You're passing in a collection of custom field objects, because you're using getCustomFieldObjectsByName() to get the field. That seems to be causing the error.

Use

def cfFuncDate = customFieldManager.getCustomFieldObject("Commission Date")

to get a single custom field object

Thanks for the quick response.  That definitely fixed the reported errors.   I replaced my assignment with yours and it removed the compiled errors on the screen, but when I ran a test case I still received an error on the next line.   Thanks again for getting me past those initial errors.

Hi Michelle,

No problem. From the new error, it sounds like the custom field object is null. Are you sure the field is called "Commission Date" and not something like "Commission_Date"?

I'd put in an assert statement to quickly test whether or not the custom field object is null. Check the run history for the post-function whenever you test it again:

import com.atlassian.jira.component.ComponentAccessor

import java.sql.Timestamp

def customFieldManager = ComponentAccessor.getCustomFieldManager()

// get today's date
def today = new Timestamp(new Date().getTime())
def cfFuncDate = customFieldManager.getCustomFieldObject("Commission Date")
assert cfFuncDate != null
def funcDate = issue.getCustomFieldValue(cfFuncDate)
if (!funcDate) { // if this field is empty, then the current date is set for this field
    issue.setCustomFieldValue(cfFuncDate, today)
}

While your script is pretty much correctly written, you might also like our new free Script Library site that we've launched. We have tons of example scripts, including an example of how to set a custom field in a workflow transition.
