Behaviour: formField.setFormValue causes java.lang.StackOverflowError Edited

[Jens Kisters _APTIS_]

Hello,

i am trying to set a formfield using a behaviour.

The data i am trying to set is read from another issue.

When i try to set the field value like this

Issue presetFound = (Issue) issueIterator.next()
Customfield field = customfieldManager.getCustomFieldObject(11603L)
java.lang.Object fieldValue = presetFound.getCustomFieldValue(field)
if (fieldValue != null) {
   com.onresolve.jira.groovy.user.FormField formField = getFieldById(field.getId())
   errorMessage += "set field " + field.getId() + " to " + fieldValue.toString() + ", field is " + formField.getClass().toString()
   formField.setFormValue(fieldValue)
}

When i comment out the last statement the errorMessage is 

set field customfield_11700 to KLE-VE-4753 field is class com.onresolve.jira.groovy.user.FormField

When the statement is not uncommented the beheviour is not executed and this errror is logged:

Hi @Jens Kisters _APTIS_,

your are add an Object to custom field and this cause the error. Please, could you verify what is the type of your custom field?

If it is a text, you need to add String as value, if it is a select list you need to add an Option and so on.

Great, that was exactly the problem.

Thanks a lot!

You're welcome Jens!

Hi Jens, can you provide the full working code?

[Jens Kisters _APTIS_]

Hi Bryan,

i have nothing i can quickly paste for you, but the working version should be something like this (3rd line is the one with the change):

Issue presetFound = (Issue) issueIterator.next()
Customfield field = customfieldManager.getCustomFieldObject(11603L)
String fieldValue = (String) presetFound.getCustomFieldValue(field)
if (fieldValue != null) {
   com.onresolve.jira.groovy.user.FormField formField = getFieldById(field.getId())
   errorMessage += "set field " + field.getId() + " to " + fieldValue.toString() + ", field is " + formField.getClass().toString()
   formField.setFormValue(fieldValue)
}

Am I the only one left wondering why this causes a StackOverflowError?
