Hi,

Try this:

inputa = values with abcd etc

input b = numerical values

Create a UDF for queue and give inputa and inputb as inputs to the UDF.

inputa > removecontext->UDF

inputb > removecontext->

int k=0;

for (int i=0;i<inputb.length;i++) {
 for (int j=0;j<Integer.parseInt(inputb<i>);i++) {
   result.addValue(inputa[k]);
   k++;
 }
 result.addContextChange();
}

Hi ,

You can also try this :

int countold = 0;

int countnew = 0;

int k = 0;

for(int i =0;i<var1.length;i++)

{

countold = countnew + 1;

countnew = countnew + Integer.parseInt(var1<i>);

for( int j = countold-1 ;j<countnew;j++)

{

result.addValue(var2[k]);

k++;

}

result.addContextChange();

}
