RE: [HAPI-devel] How to get null in the generated message?

[<Fre...@cl...>]

Hi,

Calling

	value.setValue("\"\"");

do work, except for date/time/telephone datatypes which do format=20
checking. I've made the following modifications, all in package=20
ca.uhn.hl7v2.model.primitive (I still use release 0.3):

In CommonDT.java, method setValue (line 88):
        if (val!=3Dnull && !val.equals("") && !val.equals("\"\"")){

In CommonTM.java, methods setValue (line 117):
        if (val!=3Dnull && !val.equals("") && !val.equals("\"\"")){
and getValue (line 479):
        if (value!=3Dnull && !value.equals("") && !value.equals("\"\"")){

In CommonTS.java, methods setValue (line 121):
        if (val!=3Dnull && !val.equals("") && !val.equals("\"\"")){
            ...
            if (val!=3Dnull && (val.equals("") || val.equals("\"\""))){
                dt =3D new CommonDT();
                dt.setValue(val);
                tm =3D new CommonTM();
                tm.setValue(val);
            }//end if
and getValue:
        if(tm!=3Dnull && value!=3Dnull && !value.equals("") &&=20
!value.equals("\"\"")){

In CommonTN.java (line 110; not tested yet!):
        if (value!=3Dnull && !value.equals("") && !value.equals("\"\"")){
            ...
        }
        else{
            if (value.equals("\"\"")){
              countryCode =3D "";
              areaCode =3D "";
              phnNumber =3D value.trim();
              extension =3D "";
              beeper =3D "";
              comment =3D "";
            }
            else{
                //set the private value field to null or empty space.
                countryCode =3D value;
                areaCode =3D value;
                phnNumber =3D value;
                extension =3D value;
                beeper =3D value;
                comment =3D value;
            }
        }//end else
   =20
By the way, there is a little bug in this method setValue: if the phone=20
number starts with an hyphen (-), an IndexOutOfBoundsException occurs.=20
I've changed like this (line 171):
                // if (hyphen =3D=3D -1){
                if (hyphen < 3){
                    String msg =3D "The phone number component must be=20
supplied and should " +
                    "be in the following format [999-9999]";

Yours,
