StringIndexOutOfBoundsException opening a modal window

Hi, I’m getting a strange error and it seems not related to our app code, opening a modal window. Any ideas ? Thanks !

Exception:

Hello!

Could you clarify in more detail how do you get this exception? Steps to reproduce or a small demo project with the reproduced issue would be helpful. Also, what version of CUBA do you use?

#4

Sure Roman, I’m sorry.

CUBA version is 6.10.19. It is very strange because in several PCs it works fine and in others not and I can’t find the pattern yet. I’ll try to make a small project. The exception occurs when calling this method:

{     

Map<String,Object> params=new HashMap<>();     
params.put("originScreen", this);     
AbstractWindow modal=openWindow("substanceType", WindowManager.OpenType.DIALOG.center(),params);  

modal.addCloseListener((String actionId) -> createItem(actionId));   
}

Unfortunately, I cannot reproduce the issue. What operation system and browser do you use? Also, check the deploy/tomcat/conf/app directory maybe some hot-deployed files are not removed?
