Control addin event arguments

Posted on by josalm

Hi,

According documentation the arguments in events within control addin must belong to an array.

I can't understand how should this work with arguments. Here's my code:

AL:

trigger PreviewDocument(DocId: Text)

begin

Message('Trigger PreviewDocument Invoked');

end;

AL Control Addin:

event PreviewDocument(DocId: Text);

Js
script: (this is where the button is added inside a loop) In here, i
tried without the brackets, with them and with and without question
marks.

document.querySelector('buttonPreview').addEventListener('click', previewDocumentFunction);

After inspect the page:

Nothing happens after the click.

Any ideas?

Hi,

To correctly pass the DocId as an array to the InvokeExtensibilityMethod, you need to ensure that the JavaScript function receives the DocId as a single value and then wraps it in an array when calling the extensibility method. Here's how you can adjust your code:

function previewDocumentFunction(DocId) { Microsoft.Dynamics.NAV.InvokeExtensibilityMethod('PreviewDocument', [DocId]); }

Update html <div id="buttonPreview"> <button onclick="previewDocumentFunction('" + DocId + "')">Preview</button> </div>

the event should fire correctly, and the DocId should be passed to the AL trigger
