Hi everyone,

I have a diagram where I have used couple of throw link and catch link events through tasks.

After a while I wanted to add one more throw link to my diagram.  
After I put it on the diagram I have no control on it, down on the menu I have properties of the pool instead of this new throw link.  
When I click on a empty space near it the icon of throw link disappear and remains only that cross error where it says that “the event has no target defined”  
I click on it, and again - its own menu where I should have choose a target doesn’t show.  
I’ve noticed this happen to any Event which I want to add.  
On a older version of this diagram it works fine, but I have a lot of major changes … I need this new diagram working

Is there any possibility to fix a diagram?

Thank you  
Petru

Hello, could you please share a screenshot ? and tell us the version of your Studio, your operating system, and Java version/vendor ? I will also notify the Studio team.

No idea?

This is about adding any event into an existing diagram(Start, end and int events). It doesn’t work anymore. Also can’t edit existing events…

I’ve noticed that if I add a new pool to this diagram I can create anything on it, but on the existing old one I can’t.

Cheers
