Missing Dependency open-tabs in Thingworx Mashup

JK_10744682 — Thu, 23 Oct 2025 12:00:35 GMT

Hi all,

On version 10.0.0 and this is an issue I am just noticing as of recent (maybe just after updating our dev to 10.0.0). There is this dependency with an entity called 'open-tabs' but I don't see it used anywhere in the mashup and don't even know what the entity is (based on name seems like a default thingworx entity). Any ideas on what this is or how to resolve this dependency?

Icon indicates that it is a StyleDefinition.

Maybe export the mashup as xml (export to sourcecontrol) and search the xml for the "open-tabs" reference. Maybe it helps to recreate the StyleDefinition - or remove it when you know where it is referenced in the mashup.

Not sure if this was a custom created StyleDefinition or from some other extension.

I found it has something to with this TabStyle property which is new in TWX 10.0.0.

If I switch it to "Framed Tabs", I then have an issue with a style definition called 'contained-tabs' instead. Though I don't see anywhere to switch the actual style definition that is used and open-tabs was not a custom created one. I find that creating a custom style definition named 'open-tabs' resolves the dependency issue, just am not sure if I am missing some sort of new built-in/system dependency named 'open-tabs' instead.

"TabStyle" : "open-tabs"
XML shows me also that it is with the TabStyle, but I can't physically remove it from the mashup in any way it doesn't seem.

hm sounds like a bug. I also can check tomorrow in a twx 10 instance of mine

Thanks for the input. For now, simply creating a new style named 'open-tabs' seems to resolve the dependency, just seemed like a weird behavior so wanted to see if anyone else encountered it

In a fresh TWX 10.0.0 instance this StyleDefinition does also not exist. I see in a export mashup with tabset widget also the same like you "TabStyle" open-tabs.

But I wonder where do you have this screen with missing dependencies? Has this something to do with solution central?

The dependency window is for when pushing to solution central. Would not allow for pushing since the entity did not exist.

Just for awareness in case others show up here, I encountered this issue in ThingWorx v10.1.0, so it's not yet resolved.

Thank you for sharing the tip about creating a style to overcome the dependency!
