Duplicate attributes in value series pre-processing

I'm trying to learn how value series work and I'm having trouble with a particular process that I cannot get to do what I want; it errors with "duplicate attributes".

The attached example shows this. It is trying to find the maximum frequency index and its amplitude for a number of windows within an example.



































<操作符的名字= "找到最大频率cy within each window" class="OperatorChain" expanded="yes">



<操作符的名字= " OperatorChain(4)“=”操作符rChain" expanded="yes">









<操作符的名字= "找到最大频率cy index within each window" class="OperatorChain" expanded="yes">

















If you run it, you will get the duplicate attribute error. If you disable either one of the branches, the example will succeed. In one case, the maximum index within each window will be found, in the other case, its maximum amplitude. Try as I might, I cannot get both to be output at the same time.

Before I embark on a workaround to perform the process twice and merge example sets, is there any way what I want to achieve can be done?

    After a bit of fiddling around, I crafted the following workaround.






































    <操作符的名字= "找到最大频率cy within each window" class="OperatorChain" expanded="no">



    <操作符的名字= " OperatorChain(4)“=”操作符rChain" expanded="yes">
























    <操作符的名字= "找到最大频率cy index within each window (2)" class="OperatorChain" expanded="no">



















    However, it would be nice if I didn't have to do this - is there a better way?
