[SOLVED] strange behavior with new versions
Hello,
Are some versions (=> 5.2.008) that behaves in a strange way the piece of code that you find on the underside.
In short, the error occurs in the append, caused by the different type (nominal, real), this happens if there are no records that pass the filter (Channel
.
The last working version for this example is 5.2.006.
sorry for my English but google is my friend
Thank you very much and good day

That is indeed nasty. We already have an internal issue for that, but until it is fixed you can work around that by applying a Parse Numbers operator after the attribute generation. Select the generated attribute to be parsed. If it is already numerical (when the example set is not empty), it does nothing; if the example set is empty, it simply switches the data type from nominal to numerical.
