Available Conditional Build Tag Expressions

[Guest]

I'm part of a team that works on a version control project that encompasses content across numerous business lines with a lot of shared content between them. This means that we use conditional tags quite a bit. I'm new to the group and have been playing around with the tags in the topic, previewing it, and then experimenting with different tag expressions to see what is made invisible and what remains.
But now, all of the tag expressions that I defined in the preview window while messing around are still present and I can't remove them. All of the new expressions really crowd out the standard set we use for legitimate testing and I just know this is going to piss my co-workers off.
Please, any help you can provide in undoing the useless clutter I've created would be greatly appreciated.

Yes, the items in the "Conditional Build Tag Expression" list in the topic preview window. The expressions I'd previously defined will not go away.

When you generate the help, are the expressions also showing in the dropdown there. Sorry to be labouring this but the solution has worked for everyone else so it is difficult to understand what is going wrong here.

Also are you using version control and could that be pulling something in?

[Just_Mary]

Yes, the same expressions are available when I go to generate a build from one of the layouts. I'm not using version control, so I'm not sure what could be happening....

[Just_Mary]

Oh, I see -- an expression that is saved as part of a single source layout can't be removed from the expressions available for the topic preview. I'm not sure that that's how I necessarily want it to work, but it makes sense now at least.

Deleting the PSS and the CPD should have removed them from both locations. Can you please clarify what happens after deleting the PSS and CPD?

Are you still seeing them in layouts?

Are you still seeing them in topic preview?

Deleting the PSS and CDP file deleted all build tag expressions that I had manually created in Preview mode. However, the build tag expressions that are part of a build tag (such as WebHelp, Printed Documentation, and so on) are still listed in Preview. I'm assuming Adobe figures that you'll want to be able to preview topics using the expressions that are applicable to your output, so when you save a build tag with specific expressions, the expression is added to the list automatically (thereby saving you the trouble of doing it manually).

The build tag configurations are saved in files called <build tag>.ssl, so they are not deleted when you delete the PSS and CDP file.

[Peter Grainge]

Apologies. There is one additional step that I had forgotten. You have to go to the layouts, right click and select Properties and then set the Build Expression to None.

If you do that and Save, then there are no expressions in the layouts and they all get deleted.

If you don't do that, an SSL might have several expressions listed before you delete the PSS / CPD and afterwards it will just have whichever one was selected in the layout at the time.
