"[Solved] Missing id attribute after Windowing operator"
Contributor II
Dear all,
Seems that I have discovered yet another bug today:
Let's assume that I have 3 attributes as input for the windowing operator
date (as ID)
figures1 (without special role)
figures2 (without special role)
Windowing operator provides the following output
date (as ID)
label (as label)
figures1-0
figures2-0
However, the "date" attribute is kind of hidden. I receive it in the results perspective but i cannot use it in other operators like "select attribute" operator (unless I change the role before). In the "select attribute" operator the "date" attribute is not shown.
PS: Another remark to the windowing operator:
It would be better if this operator would not rename the attributes like "name-0" but "name_0". Reason is that the "generate attributes" operator has problems in using this wording in the function expression because is seems to interpret it like "name minus zero".
Cheers
Sachs

you can use the date attribute in subsequent operators - just type it into the combobox instead of searching it in the list. However, you are right that this is a bug and it should be shown in the list.
Your suggestion of the naming of the creating attributes sounds reasonable, maybe we'll change that in a future release.

Hi, --> The proposed workaround works for most of the operators. However, if it comes to "pivot" operator it won't work unless you save the example set in a file and recall it afterwards.
Bye for now

Here you are
I spent some more hours in error diagnostics... without success... but I feel like that it depends either on the "date" data type or that date has the role "id".
Also strange: The process doesn't through an error but the result is not the one I would expect.
Moreover, I tried to save the result in an excel file and read it again immediately before pivotizing. That's how it worked out well. *puzzled* ???

special attributes (like date in this case) have to be set to regular before applying the Pivot Operator.
Here you go: Best,
