spotfire - Better way to refresh imported columns?

Question

I have a table in spotfire with a couple columns imported from another table as a lookup. As an example, Col2 is used to match for the import of ImportedCol:

+------+------+-------------+
| Col1 | Col2 | ImportedCol |
+------+------+-------------+
|    1 | A    | Val1        |
|    2 | B    | Val2        |
|    3 | A    | Val1        |
|    4 | C    | Val3        |
|    5 | B    | Val2        |
|    6 | A    | Val1        |
|    7 | D    | Val4        |
+------+------+-------------+

However, the data in Col2 is subject to change. In that event, I need ImportedCol to change with it, however Spotfire seems to just keep the old imported data. Right now I've been deleting the imported column and re-adding it to refresh the link. Is there a way to dynamically import the data as the document loads or with any refresh of the information links?

Answer 1

I have found that this happens sometimes although I'm not exactly sure how to explain why. my workaround is to create "virtual" data tables based on your existing ones.

consider your linked table as A and your embedded table as B. start from a default state -- that is, before importing any columns.

add a new data table. the source for this table should be "From Current Analysis" and using A. we will consider this one as C, and it becomes your main data table, and C will update when any changes are made to A or B.
