9.1.1.1    HANDOVER REQUEST
RRC Context
Includes the RRC Handover Preparation Information message as defined in
subclause 10.2.2 of [9]. 

However the x2ap.cnf is trying to dissect the rrc context as handover command
instead of handover preparation

#.FN_BODY RRC-Context 
#VAL_PTR = &parameter_tvb
# Includes the RRC Handover Preparation Information message as defined in
# subclause 10.2.2 of [9].
# [9] 3GPP TS 36.331: "Evolved Universal Terrestrial Radio Access (E-UTRAN);
Radio Resource
# Control (RRC) Protocol Specification".
  tvbuff_t *parameter_tvb=NULL;
  gint32 start_offset;

  start_offset = offset;
%(DEFAULT_BODY)s
  parameter_tvb = tvb_new_subset(tvb, start_offset>>3, -1, -1);    
  if (!parameter_tvb)
    return offset;
  dissect_lte_rrc_HandoverCommand_PDU(parameter_tvb, actx->pinfo, tree);
