tSample row component not resolving value of context variable.

Attached is the simple usage of tSampleRow.

tJavaRow_3 component:

String range = "1,33";
context.range = range;

Expression in tSampleRow:

context.range

Any clues?

Assign value to contect variable via directly or load via file & then use, it will work. Value set in tjavarow is not globally set thus tsamplerow unable to understand.

Please refer attached screenshot, tSampleRow properly able to read context. Also find attached sample job.

Didn't know about that tJava part.

Also I tried to set value in global map but I wasn't able to resolve it because of typecasting issues.

I managed to do that with other logic.

Thanks for clearing the confusion.
