Edit Data by Selecting Table Row

Hello, I’m trying to edit data by selecting table row in the form. Once the table row selected, the row contents displayed in the text fields and then change any text field value as i want. But i’m having an issue here. When i pressed the submit button, nothing changed instead of giving me a new row filled with null in H2 Console. Here i already put my .bos file so you can check and figure out what went wrong in my project. I’m using bonita 7.92 version. Make sure run the table TEST Update 1.0.proc to see and test the edit data and see the error. Im looking forward the solution of this. Thank You
