RE: Event Handler Doesn't get Parameter

You forgot to tell us, but the second screenshot suggests that the handler is attached to update() method of PurchTable table. Is it the case?

The first screenshot highlights _args.getThis(), therefore I assume there is the problem. What happened? Does it execute without error but it returns an empty record?

Hi Martin Dráb,

Yes it attached to update method on PurchTable

It execute (compile) without error, but _args.getThis() can't get purchTable, always return empty record like you said

Here is I attached when debugger is running

I don't know what's wrong on my code

Any suggestion?

What about the other event handler for the update method, do you see PurchTable buffer there if you debug? Could you share the code of the other event handler, too?

In your latest screen shot we do not see the call stack - could you share that too? Just to double check it's coming from PurchTable/update.

RE: Event Handler Doesn't get Parameter

Hi Nikolaos Mäenpää,

All right one by one

Here is the code for sendEmailAfter

public static void sendEmailAfter(XppPrePostArgs _args) { PurchTable purchTable, purchTableUpdate; purchTable = _args.getThis(); try{ //Bintang Check if Status Confirmed send email if(purchTable.DocumentState == VersioningDocumentState::Confirmed && purchTable.EmailSent == VDI_YesorNo::No){ //filename = this.getFileReport(this.PurchId); purchTable.sendEmail(purchTable.PurchId); update_recordSet purchTableUpdate setting EmailSent = VDI_YesorNo::Yes where purchTableUpdate.PurchId == purchTable.PurchId; } } catch{ error("Could not send email, please ask support"); } }

and this is from another event handler (afterConfirmPO), attached to update method on PurchTable and PurchLine

public static void afterUpdatePurchaseOrderLine(XppPrePostArgs _args) { Common common = _args.getThis(); VDI_PurchTableCustomGridHandler purchTableGridUpdate; purchTableGridUpdate = VDI_PurchTableCustomGridHandler::newFromTable(common); purchTableGridUpdate.run(); }

When I debug afterConfirmPO (afterUpdatePurchaseOrderLine), _args.getThis() gets data from PurchLine, but can't get data from PurchTable.

Here is the screenshot

Is there any problem with PurchTable?

It works fine in my environment.

A side note: your catch statement won't work if update() is called in a transaction.

RE: Event Handler Doesn't get Parameter

Bintang, could you share the call stack for the PurchTable event handlers?

Also do you have any customization in the PurchTable/update method itself?

RE: Event Handler Doesn't get Parameter

Based on the call stack you are updating purchase line in the user interface, not purchase table. Does your event handler work if you actually change the values of purchase order header and save?

Dear Nikolaos Mäenpää ,

It's the same , last time I changed Language on Header View Purchase Order but still doesn't get PurchTable as a parameter from _args

On the other process , I have update_recordset to PurchTable too
