Hi Wolfgang,
This problem has been resolved now. I wrote the rule that you gave me, and found out that
the control was only considering the last row and the remaining rows were not considered
for execution.
I was trying to look for a solution in the Session and the ArrayList details of the
session.
I rectified it by creating a different object inside the loop when reading values, so
that the original value was not modified.
The Old code for reading the objects was
DailyPLC plcToday = new DailyPLC();
for(int iLoopIndex = 0;iLoopIndex <4; iLoopIndex++)
{
plcToday.setSrceSysId(data[iLoopIndex][0]);
plcToday.setProductCode(data[iLoopIndex][1]);
plcToday.setDistributorCode(data[iLoopIndex][2]);
plcToday.setDuePeriod(data[iLoopIndex][3]);
plcToday.setTimePeriodStartDate(data[iLoopIndex][4]);
plcToday.setRowNumber(iLoopIndex+1);
alPLCArrayList.add(plcToday);
}
Which I modified to
DailyPLC plcToday ;
for(int iLoopIndex = 0;iLoopIndex <4; iLoopIndex++)
{
/** will need to create a new object every time and
* assign it to the same reference.
* This is because in case the object is same,
* the value gets modified after
* every execution. ( Pass by value and reference )
*/
plcToday = new DailyPLC();
plcToday.setSrceSysId(data[iLoopIndex][0]);
plcToday.setProductCode(data[iLoopIndex][1]);
plcToday.setDistributorCode(data[iLoopIndex][2]);
plcToday.setDuePeriod(data[iLoopIndex][3]);
plcToday.setTimePeriodStartDate(data[iLoopIndex][4]);
plcToday.setRowNumber(iLoopIndex+1);
alPLCArrayList.add(plcToday);
}
Thank you so much for investing your time on the problem. It really helped.
Regards,
Amal

The rule you've shown will fire for all 4 elements created from the 4 rows of your
table.
Something might have gone wrong while constructing the objects or the list.
To see what you have, add this rule, which should print the IDs of all DailyPLC objects.
rule show
when
plc : DailyPLC();
then
System.out.println(" ID " + plc.getId()+ " at row : " +
plc.getRowNumber()); end

Hi Wolfgang,
Thanks for your response.
Here is the rule that I had written for the file.
rule "Id != value"
when
plc : DailyPLC(Id!="1794");
then
System.out.println("Incorrect ID " + plc.getId()+
" at row : "
+ plc.getRowNumber()); end
Any pointers shall be really very helpful.
Regards,
Amal

Your question can't be answered without the rules. - If your Java
code
does what you say it does, then it should be OK.
