You will find the error codes in the header files in the include directory
here it must be something wrong with the group name as input
POM_ask_group_tag(const char *group_name_string, tag_t *group_tag)
Name given is not a known group. Check that the group does exist.
#define POM_unknown_group (POM_error_base + 142)
and you find them in the text files under %TC_ROOT%\lang
e.g. inside pom_errors.xml
<errors module="pom" error_base="515000">
<error id="142">The given group is unknown.</error>
Yes. Thanks !
I was searching for the entire code, and did not realize there was a generic prefix (i.e. 515 ).
grepping for '142' found the codes.
