integer.gadget in page layout

Hi,

I am trying to use an integer.gadget in an dynamical GUI-Layout. If I add the gadget to an emtpy window, everything works fine. But if I try to do the very same in a page-layout, the string-box of the IntegerObject is missing.
In both cases I add the gadget to a vertical LayoutObject. What is different, when adding a gadget to a page-layout?
Below is the code I use.

AND

  1.          child = IntegerObject,
  2.                         GA_ID,             id,
  3.                         GA_RelVerify,      TRUE,
  4.                         GA_TabCycle,       TRUE,
  5.                         INTEGER_MaxChars,  9,
  6.                         INTEGER_Number,    *(ULONG*)ap[i].Variable,
  7.                     End;
  8.          child = add_child(obj, child, 0, 0, lab);
  9.  
  10.            ...
  11.  
  12. Object *add_child(Object *lay, Object *child, int w, int h, STRPTR label) {
  13.    BOOL added = 0;
  14.    struct TagItem attrs[] = {
  15.       {CHILD_Label, 0},
  16.       {CHILD_WeightedWidth,  0},
  17.       {CHILD_WeightedHeight, 0},
  18.       {TAG_DONE, 0}
  19.    };
  20.  
  21.    if(!child || !lay)
  22.       return NULL;
  23.  
  24.    if(label) attrs[0].ti_Data = (ULONG)pLabel(label); else attrs[0].ti_Tag = TAG_SKIP;
  25.  
  26.    attrs[1].ti_Data = w;
  27.    attrs[2].ti_Data = h;
  28.    if(w == -1) attrs[1].ti_Tag = TAG_SKIP;
  29.    if(h == -1) attrs[2].ti_Tag = TAG_SKIP;
  30.  
  31.    struct lmAddChild msg;
  32.    msg.MethodID       = LM_ADDCHILD;
  33.    msg.lm_Window      = NULL;
  34.    msg.lm_Object      = child;
  35.    msg.lm_ObjectAttrs = attrs;
  36.  
  37.    added = IIntuition->IDoMethodA(lay, (void*)&msg);
  38.  
  39.    return added ? child : NULL;
  40. }

If you could supply a fully

If you could supply a fully working example (or the code for it), that may help in tracking down what is happening here.

Well, I guess there is something wrong with the setup of the page-gadget/clicktab-gadget.
OBJ_INTEGER_1 is crippled, whereas OBJ_INTEGER_2 works just fine.

Thanks for the example. There

Thanks for the example. There is definitely something wrong here, because Intuition has recognised a problem before the integer.gadget in the page layout is fully drawn. This is shown by trying to resize the window, and the complete machine lock that results.

I'm investigating....
