Initializing form event is not triggered

Hello,

I created a form extansion in order to add list panel to SrmParameters form.

The panel is initialised in Initializing event:

[FormEventHandler(formStr(srmParameters), FormEventType::Initializing)]
    public static void srmParameters_OnInitializing(xFormRun sender, FormEventArgs e)
    {
        FormRun            formRun = sender;
        TestListPanel  listPanel = TestListPanel::newForm(sender,
                sender.controlId(formControlStr(srmParameters, TestControl))); // parent control
        formRun.setlistPanel(listPanel);
    }
 
The problem is: after I build the project list panel is shown on the form and everything looks fine. But after I build the model, the panel is not shown and event handler method is not triggered. Any ideas why it's not triggered?

Hi,

Did you try to debug the code and see if the debugger hit the code or not?

Thanks,

Hi,

Try to use COC instead of the event handler.
[ExtensionOf(formstr(srmParameters))] final class CustTableForm_Extension { public void init() { FormRun formRun = this as FormRun; TestListPanel listPanel = TestListPanel::newForm(sender, sender.controlId(formControlStr(srmParameters, TestControl))); // parent control formRun.setlistPanel(listPanel);; next init(); } }
