Ask for reactivate Order - PROBLEM

[Andrea Checchia]

Goodmorning everyone.

I would need help to be able to ask a question before reactivating an order.

I tried to use an AbstractEventHandler class, with 

registerTableEvent (IEventTopics.DOC_BEFORE_REACTIVATE, I_C_Order.Table_Name);

but by error in the process if I want to set and open the FDialog.ask (....):

!ENTRY org.eclipse.equinox.event 4 0 2019-02-28 08:50:27.232

I wanted to try to intercept the "WorkflowProcess" and use the method

SvrProcess.processUI.ask (String message, Callback <Boolean> callback)  

but for example

Env.getProcessUI (Properties ctx)

returns NULL.

Do you know to tell me, please, how can you solve this?

Thanks in advance.

Hi,

I don't think it is possible to open a popup from an Event class.

I see 2 options :

 #1 : use a process instead

 #2 : customize directly WDocActionPanel and do something similar to the line 364 : if(clientInfo.isConfirmOnDocClose() || clientInfo.isConfirmOnDocVoid()) ; ugly but it should work

Regards,

Nicolas

Thank you Nicolas for your answer.

I will try the solution n. #2 and I'll see if I can solve the problem.

Thanks a lot.

Andrew.

Hi Nicolas,

Thanks a lot. I followed your advice (solution #2) and it worked !!

Thanks again.

Andrew.
