In the action tab I have an action that “Updates a few rows in this table” all of the columns are setup the same. However one of the columns is hidden in the *Position view, but shown in the **Attache to view
All of the other colons are showing. "Any suggestions as to why this column is hidden. It’s exactly like the ones showing?
Please check if that column has any different show_if, editable_if, valid_if constraint different than other similar columns where you are able to set the actions.
Edit: If the above suggestion does not work, please elaborate what you mean by position view and attached view.
Is the column a key column, or is it used in an expression to generate the key column? If so, the column’s value cannot be changed after the row is saved the first time.
Try checking the Brake lining 1 column, in the update behaviorchecklisteditable section, if you want to appear in the action for data set values of some columns in this row.
I have already suggested the same thing to @Jack_Bates and it sounds that probably editable_if constraint was an issue based on the acceptance by him it as a solution.
