Concatenate field value in a java.list?

[dox102000]

Hello

I have a request and I would like to put the results of a column of this request in a list.

I saw in the creation of a variable that you can take the first, do the sum ... but nothing to put in a list or something like that.

I need the values in this list as parameter in a subdataset.

 

Is it possible ?

 

Thanks,

Finally, I found a solution.

I created a variable with java.utils.ArrayList as type.

Calculation: system

Value Expression: $V{MyList}.add($P{TheParamToAdd})

Initial Expression: new java.utils.ArrayList()
