getUnderlyingDataAsync() and getSummaryData() returns all columns as string

[gyulalaszlo]

When using getUnderlyingDataAsync in Tableau Desktop Beta build 17.0929.1346 the returned columns are always reported as having string dataType.

When testing with Superstore, calling (example code)

worksheet
    .getUnderlyingDataAsync({
        maxRows          : 0,
        includeAllColumns: true
     }).then( table => table.columns.forEach(c=>
         addToLog(`${c.name} : ${c.dataType}`)
     ));

results in:

...
Category : string
Order Date : string
Order Profitable? : string
...

Other Tableau workbooks also exhibit the same behaviour, as have previous versions of frelard.

Yeap, this is definitely our bug, was able to reproduce with any sample.

This appears to still be present in build 2018.2 Beta 1

This has been fixed internally, and will be part of our our next release. Thanks!

Has this already been released? If so, which Tableau version contains the bugfix?

[johnDance]

Hi, this should be fixed in the final 2018.2 and all releases going forward.

Closing this as it was fixed in 2018.2. This is different from the bug with values being returned as strings which we will keep track of in #192.
