scriptrunner script how to check the condition if attachment was added (uploaded) in post function

[uvo3 main public name]

I'm wondering,
How to check condition in the post function by script runner script  :
Is an attachment was added from transition screen or not?
I'm working on add the condition in my code. The idea is check if attachment was added in transition screen. My script placed in post function 

Is it possible to grab files attached on transition screen by Scriptrunner custom script in post function?
The add attachment is not mandatory action.

Hi there,

Apparently you can achieve this by going through the modified fields in the postfunction.

These articles should get you on your way

Thank you for your suggestion.
I'm afraid this way doesn't fit me because
The aim is check attch adding action in the post function
Is it possible to grab files attached on transition screen by Scriptrunner custom script in post function?
when adding attachment is not mandatory action.

I think the first link (further in the comments) describes just that, checking the files added in the transition, on the transition screen.

Unfortunately, It doesn't work in post function.
The code works well as validator in Validation of transition

Euuu  ;) Thank a lot for you help.
The suggested approach works well for me.

I've move my script to Validation of transition from Post function. It was so easy.
Thanks again.

One more things. Do you know is it possible to get Attachments from Validator?

Hi,

I'm not sure but since the attachments are already on the issue when the Validator tiggers, I think you can just use the attachmentManager service. This article should get you started (the code in the question, not the answer :-)):
