Hello,
We are using Query Issues Custom Fields plugin. One of the fields is Query issue multi linker custom field wich stores data in an array.
To change data in that field without user interaction we use:
def cField = customFieldManager.getCustomFieldObject(cField_ID)
def tmp = new ArrayList<String>()
tmp.add(issue.key)
issue.setCustomFieldValue(cField, tmp)
issueManager.updateIssue(
currentUser.directoryUser
, issue
, EventDispatchOption.ISSUE_UPDATED
, false);But it updates that field value for an issue.
What we need to achive
When we call a transition_1 we have a screen with an emty Query issue multi linker custom field.
We need to push some data into that field on screen load. And that data should not instantly update an issue field, but be present on that screen only until form is submited. Any advice on how can we achieve that?

If this situation is plugin scpecific, maybe someone could help me with the sources of that plugin (maybe to achive my goal I have to import some class of that plugin?)
