updateValue () OR createValue()

[Mikkel Kragelund Nielsen]

Hey

I have a eventlistner, that have to either change the value of a custom date field.

But i can't seem to determin when to use createValue() and when to use updateValue() method.
How do i test if the custom field value is set for a issue?

I have tried to get the customfield like this:

CustomField test = componentManager.getCustomFieldManager().getCustomFieldObjectByName(<<Name>>)

And then the the value for the issue:

issue.getCustomFieldValue(test)

If i get a NullPointerException, i use createValue, if not i use updateValue.
But this dosen't seem to work.

Hi,

try

MutableIssue.setCustomFieldValue(customField, newValue)

and store + reindex issue.

If you want to have change record in history tab use something like this:

if (!dummy) {
	// Update history for existing, no dummy issues
	customField.updateValue(
		fieldLayoutItem,
		issue, 
		new ModifiedValue(oldValue, newValue),
		changeHolder
	);
}

Hey

I don't see how this solves the issue?
Does setCustomFieldValue deside if the value is to be created or updated?
