7. ... AND DIVERSE
In this report, you have defined a parameter named blocksize,
which is given a value of "7|D|1|D". In open script of data set,
there are below lines code:
<script begin>
token=Packages.java.util.StringTokenizer(params["blocksize"],"|");
vec=new Packages.java.util.Vector();
while(token.hasMoreTokens()){
vec.addElement(token.nextToken()); Eclipse #150222
}
params["DateRange"]=java.lang.Integer.parseInt(vec.elementAt(0));
</script end>
Since the value of params["blocksize"] is "7|D|1|D", vec.elementAt(0)
is "7", and then it can not be parsed to int value. In 1.0.1,
the value of params["blocksize"] might be 7|D|1|D, so it can be
parsed to int value of 7.
