Missing Attributes in Select Attributes (Subset)

Hello (again) Forum,

 

Looks like I might be experiencing a bug that some others have seen in versions past. I'm doing some manipulation of raw JSON from a Twitter feed and am trying to use the "Select Attributes" operator to subset the attributes carried forward in my Process. It seems that after a Pivot, the "subset" feature of Select Attributes does NOT allow me to choose attributes from my example set. What's up with that?

 

Here is what my data looks like after it has been Pivoted:

2016-10-17 22_10_41-__S3streamTweet_data wrangle local_ – RapidMiner Studio Trial 7.2.003 @ 21695-E6.png

 

And here's the Select Attributes window afterward:

2016-10-17 22_12_43-__S3streamTweet_data wrangle local_ – RapidMiner Studio Trial 7.2.003 @ 21695-E6.png

 

***EDIT*** I did confirm that I can manually add the missing attributes to the subset list, I can also refer to them to rename them

    Pretty crazy but enabling the "Synchronize Meta Data with Real data" option in the "Process" menu fixed this issue. 

     

    Got the idea from a similar but different issue: RapidMiner-Studio/Log-to-Data-Missing-Attribute-Names

    I have the most recent recent version of RapidMiner and cannot get the Attributes List to show up.  I am using Read CSV - I added Guess Type and also clicked on the Syncronize Meta Data with Real Data.  I can type in the attribute - but it still shows an error but will run.  I don't recall seeing the same issues with the previous point release of RapidMiner.  Any help with this would be deeply appreciated as this has been frustrating.

    Found a solution.  Seems to work if I use Import Wizard - but not if if fill in parameters.

    After check Synchronize Meta Data with Real Data, I choose "Run anyway" in Select Attributes, the missing attributes appeared afterward.

    Remember that even when the metadata is not in sync (so dropdowns for attributes are blank or incomplete) you can always type the name of the attribute directly and assuming that attribute does actually exist it will function properly.

    Telcontar120 Thanks a lot! You saved me a lot of time and frustration. I ran a loop files that then read many cvs files, then used a Select Attributes, but i couldnt get it to work until i added the attribute just like you explained.
    Thank you again!

    I run into the same problem - a simple Read CSV, followed by a Select Attributes with an empty left panel. Solved it by following the above "After check Synchronize Meta Data with Real Data, I choose "Run anyway" in Select Attributes, the missing attributes appeared afterward. " for which many thanks!

    Just seems foreboding ... if such a basic bug is not being fixed 4 years (!) after being reported

    In my case, by enabling the "Synchronize Meta Data with Real data" option in the "Process" menu(answers from Rapid Miner Community Forum) didn't bring any success.

    I found that the reason behind this blank attribute list in select attribute subset was the meta-data and the original csv data had meta-data missing. Later, I try with "Import Configuration Wizard" option of "Read CSV" operator and then get success where this option automatically add meta-data after reading the file.
