Problem with function calls

I was trying to use a simple button to call a test function, the exported code is:

static void ui_event_buttonTest(lv_event_t *e) {
  lv_event_code_t event = lv_event_get_code(e);
  lv_obj_t *ta          = lv_event_get_target(e);
  if (event == LV_EVENT_CLICKED)
    test_button(obj, event);

but in ui_helper.c I have:

void test_button(lv_event_t * e)

which cannot be compiled because the function takes only one argument.
I could manually add my own function, but it would be overwritten with every export.

Thank you for the report. I opened a ticket in for the v1.0.1 release.
