Hi Vivian Mattos 

It is really strange behevior. Could you provide sample oml file?

Hi @Vivian Mattos 

Inside the loop can you please try to use ListAppend client action instead of assign, bcoz in each iteration of list lista3 will assign current value in list GuardaTodosNames23.  

I hope it'll help you.

Thanks

Hi Vivian,

You don't need to use loop, you can direct assign one list to another in assign

then use that list in string join

Hej Vivian,

the reason is pretty simple. You are not using the result of the string join and that is why the result in debugging mode is empty. To use (and therefore execute the String_Join) add another parameter to your action and assign the result of the string_join to that variable. Then you can view the result in the debugger.

I did the things that you suggest for me, but continue without to appear.

It's as if the project didn't see and undertanding the Extension Text 

I saw this information, that I sinalized with red arrow.

I'm using Outsystem version 11.54.67.

Will be that it's for this reason ? The extension isn't work with other version ?

Hi @Vivian Mattos 

I have attached oml file and its working
