[SOLVED] Order of columns changes randomly?

Hi everyone,

i do some estimations via artificial neural networks using rapidminer and extract my estimation-results into xls-Files for further research and analytics.

When i look into the result-files or use them in other Rapidminer Processes i noticed, that sometimes Rapidminer seems to change the order of the data columns by random. So it can be that e.g. the first 7 extracted result files have these order of columns: A, B, C, D , E but result file 8 has another order like A, B, D, C, E (compared to the other files columns C and D changed their positions). Is this normal or maybe a bug?

I'm using Loop-operators and analyze in every Loop different Datasets but with the same amount of columns.

    You could use the Reorder Attributes operator to put them in the order you want.

    Hello Andrew,

    many thanks for your reply! It helped a lot. But whille the ID-attribute and/or the Label-attribute are not included to be set in the "Reorder"-Operator i had to set those attributes to regular so they should be placed in my preferred order. And: It worked!
