How to use your own custom fields in desktop gadget

[Роман Симашев]

I have an issue statistics gadget

It works great with built-in types of custom field, but i need to add my own custom fields here. I implemented customfield Stattable and my fields appeared in dropdown list:

But when I choose this custom field, it drops an error

Translation: 

Failed to get the project configured for this gadget. Confirm that it is still valid in the problem navigator.

In Logs i get this error

Hi @Роман Симашев ,

what type of custom field is it? And has a project configuration been set up on this custom field that it is not for the specified project?

Regards, Marco

[Роман Симашев]

Here is a custom field initialization

public class AgreementCF extends AbstractSingleFieldType<Issue> implements RestAwareCustomFieldType, RestCustomFieldTypeOperations {

And it's searcher

public class AgreementCFSearcher extends AbstractInitializationCustomFieldSearcher implements CustomFieldSearcher, NaturallyOrderedCustomFieldSearcher

 And I do not understand what do you mean

"project configuration been set up on this custom field that it is not for the specified project"
