Action don't reflect on the application

we'd need a bit more detail into what "the add button don't give result" actually means. Does it not add a new row? It does add a new row but doesn't show any data in the drop-down? You can add a new row and select an item from the dropdown but it then disappears again? 

Oh sorry for don't give clear clarification.

I mean that the add button does not add a new row.

Ok, thanks. When you add a new row where is the data for the row being stored. Are you adding it to a local variable or to a rule input on your interface?

This is the data, it is actually dropdown field and delete button:

I am adding into Rule Input.

Hi Ammar, Could you please share the code here so that we can have a look?

Ok. So:

• a rule input (on an interface rule or an expression rule) is NOT a variable. That is, it cannot store any data because it is a pointer or a reference to a variable
• in your case I presume your interface is added to a User Input Task smart service in a process model
• unless you have a corresponding Activity Class variable defined and mapped to your rule input your data will disappear when you try and add a row
• Also unless you have defined your variable as a multiple (and array) you'll only be able to add one row

Hopefully that should give you some insight as to what's happening

I have another grid that adds a row to another rule input and it works perfectly. 

That might be true as you may be have correct mapping/cardinality in place for that, but it might be incorrect for the grid that isn't working. Check both and see if you can see what's different.

Hi, As Stewart suggested please compare those two grids , check all the parameters,
