While trying to design a custom requester for a program I'm writing, I
seem to have come across a bug in Lattice 5.04.  Whenever I try to
assign a custom bitmap to a requester, the compiler fails with CXERR
22.   If I take the same exact code, and set the image data pointer to
NULL, the code compiles fine.  Has this been fixed in 5.05? (I'm still
waiting for it to arrive.)  Or am I doing something wrong here?


Here's the offending code:

struct IntuiText ok_text = 
{
		0,				/* FrontPen */
		1, 				/* BackPen */
		JAM1,			/* Draw Mode */
		4, 4,			/* LeftEdge, TopEdge of text */
		NULL,			/* default font */
		(UBYTE *)"OK",	/* text */
		NULL			/* no more IntuiText's */
};


struct Gadget ok_gadget = 
{
	NULL,				/* NextGadget */
	100, 15,			/* LeftEdge, TopEdge */
	10, 10,				/* Width, Height */
	GADGHCOMP,			/* flags */
	RELVERIFY | 
	ENDGADGET,			/* activation flags */
	REQGADGET,			/* GadgetType */
	NULL,				/* GadgetRender */
	NULL,				/* SelectRender */
	&ok_text,			/* pointer to an IntuiText */
	NULL,				/* mutual exclude */
	NULL,				/* special info */
	0,					/* GadgetId */
	NULL,				/* UserData */
};

SHORT ok_border_points[]=
{
	0,0,
	10,0,
	10,10,
	0,10,
	0,0
};


struct Border ok_gadget_border =
{
	0,0,                /* LeftEdge, TopEdge */
	0,0,				/* FrontPen, BackPen */
	JAM1,				/* DrawMode */
	5, 					/* number of points in ok_border_points */
	ok_border_points,	/* pointer to the array of points */   
	NULL,				/* NexBorder */
};
