Error: The method append(Object) in the type StringBuilder is not applicable for the arguments ()

Hello,

I'm using an Excel (all the data are String variables) trying to merge rows with replicated values. For example, if I have 5 rows with the word Monday i want Talend to merge this information in a single row setting the same text (I'm using tDenormalize for this). This is the job:

After executing job I get this error:

Code:

I would like to know why this error in the generated code appears. Thanks!

add a delimiter in tDenormalize. This should work.

Thanks @akumar2301, that was the problem! 2 questions:

-If my Excel has null cells, how do i delete the default "null" value I get in the output? 

-I read tDenormalize can change input order. Is there any component or way to order the data again like the original order?

Thanks again!

Looks like you are trying to remove duplicated from file. You could use tUniqRow also.
I assume , tUniqRow will maintain the order of input .
