Use of Expert Info failed

[Christian Gurk <christian.gurk () mpic de>]

Hi together,

I tried to use the Expert Info feature to get a fast "statistic" about 
checksum errors in my protocol. So, when a message has a wrong CRC, I 
rise a Expert warn. It shows nicely in the message list (as a yellow 
marking), but it doesn't show up in the Expert Info Analyse Window.

Here my code snipplet:

>     if (tree) { // we are being asked for details -------------------------------------------
>         guint32 offset = 0;
>         guint32 length = 0;
>     
>         // add subtree for MPIC com7 protocol    
>         mpic_com7_item = proto_tree_add_protocol_format(tree, proto_mpic_com7, tvb, 0, -1,
>                       "MPIC COM7 frame (raw bytes: %3d, decrypted bytes: %3d, framestatus: %s)",
>                       datalen, j, match_strval(framestatus,framestatusnames));
>         
>         mpic_com7_tree = proto_item_add_subtree(mpic_com7_item, ett_mpic_com7_length);

>         proto_tree_add_uint(mpic_com7_tree, hf_mpic_com7_checksum, tvb, 0, 0, inbyte);

>                 {

> !", framecheck);
>                         expert_add_info_format(pinfo, pi, PI_CHECKSUM, PI_WARN, "CRC8 ERROR");

Did I something wrong? As I said, it works nicely for the message list, 
but not for the Expert Info Analysis. Attached a screenshot, you can see 
my "warn" Info and the following "error" warning looking quite the same. 
 I know, that the error might mask out my warning, if they're in the 
same message, but I also have messages only with a warning, the problem 
is the same...
Could anyone help me?
Thanks
Christian
