click on the "Edit Document" button while on a category row, you get a "Cannot execute the specified command" error. There is a way to prevent that error from happening. If you check the UNID of the document, Notes will return a string of zeros when you are on a category row. So your "Edit
Document" button, instead of having just the formula you would expect...
select a document"); @Command([EditDocument]))
document. That makes the error message a little friendlier while still allowing all the functionality that used to be there.
UNID = @Repeat("0"; @Length(UNID))
row. If you didn't figure out the performance hit already, it comes from the fact that all the hide-when formulas on all the action buttons will be re-evaluated every time you move in the view. If you only have a couple of action buttons, the performance hit may not be noticeable. But if you have a bunch of cascaded action buttons with hide formulas, there could be a noticeable delay moving from one document to another in the view.
