Show Dialog as Controller throws Exception

[bambo1543]

Hi all,

I try to make a dialog with a controller as described here:
https://www.thecoderscorner.com/products/arduino-libraries/tc-menu/rendering-with-tcmenu-lcd-tft-oled/
"Showing a dialog as a controller"

I want to put a second line as a TextMenuItem.

RENDERING_CALLBACK_NAME_INVOKE(dialogTextRenderFn2, textItemRenderFn, "Hallo", -1, NO_CALLBACK)

class DialogController : public BaseDialogController {
public:
    void initialiseAndGetHeader(BaseDialog* dialog, char* buffer, size_t bufferSize) override {
        // Here we should initialise the controller and fill in the buffer provided with the title
        strcpy(buffer, "Send measures");
        dialog->copyIntoBuffer("First line");
        dialog->setButtons(BTNTYPE_CANCEL, BTNTYPE_OK);

        auto* dlg = reinterpret_cast<MenuBasedDialog*>(dialog);
        TextMenuItem menuItem(dialogTextRenderFn2, nextRandomId(), 20, nullptr);
        menuItem.setActive(false);
        menuItem.setReadOnly(true);
       dlg->insertMenuItem(&menuItem);
    }
   void dialogDismissed(ButtonType buttonType) override {
        // this is called when the dialog is dismissed, the button that was clicked is provided.
        Serial.println("Canceled dialog" + String(buttonType));
    }

    bool dialogButtonPressed(int buttonNum) override {
        // this is called when a dialog button is pressed, returning true will continue default processing,
        // returning false prevents additional default processing
        Serial.println("Pressed: " + String(buttonNum));
        return true;
    }

    void copyCustomButtonText(int buttonNumber, char* buffer, size_t bufferSize) override {
        // this will be used to get the text for a button, fill in the buffer with the text.
    }
} dialogController;

void CALLBACK_FUNCTION onSendClicked(int id) {
    renderer.getDialog()->showController(false, &dialogController);
}

But I always get:
Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled.

I'm using latest libraries:
lib_deps =
davetcc/tcMenu@^4.0.0
davetcc/IoAbstraction@^4.0.0
davetcc/tcUnicodeHelper@^1.0.0
davetcc/TaskManagerIO@^1.3.5
bodmer/TFT_eSPI@^2.5.3

Does someone have an idea how to put custom menu items into the dialog without exception. For me it just worked if I add the additional items direct into BaseDialog.h and BaseDialog.cpp but of course thats not a good solution ;-)

Found the dynamicMenuItems.ino in the tcmenu source code. Everything is clear now. I'm very happy.
