positionCollect[] = {1,2,3,4,5,6,7,8,9,10};
for (int i = 0; i < positionCollect.size(); i=i+2) { polygon[i/2] = new Point(positionCollect.get(i), positionCollect.get(i+1)); }
polygon is a Point Class type list, the Point class has two value x and y.
So basically I am using 10 numbers from List, create 5 object point (CDT) , and put into list polygon.
I am pretty new to appian I don't know expression rule can do the same thing? And unfortunately I can't use java plug-in to finished this so I have to write expression rules...

a!localVariables( local!positionCollect: {1,2,3,4,5,6,7,8,9,10}, local!polygonList: a!forEach( enumerate(length(local!positionCollect)/2)+1, type!Point( x: local!positionCollect[(fv!index*2)-1], y: local!positionCollect[(fv!index*2)] ) ), local!polygonList )
In Appian all functions and rules will return a value. In the code above, I have a list of positions defined as a list and then a polygonList which calls a!forEach() which will return a list. Also, the code above will only work if your positionCollect list is even.
I don't know how to thank you for your solution! I went through the document but there are no instruction about it!
Thank you so much! It is works perfertly! Also, do you know what is the best way to learn Expression Rules instead of posting question here? Seems like the document skip over many concept..
