I have a field of zip code and auth code where I want to restrict user from entering more than 4 characters on runtime. This is what I am trying- 1. I limited my entities attribute length to 4 characters. 2. I put the custom length in textbox as 4. 3. Also I tried to put input mask as 9999 PROBLEM- On giving custom length, it is restricting in mendix emulator but on device(mobile phone) it is not restricting. On giving input mask, it is restricting to user from entering more than 4 digits but once you give your value; the textbox is freezing and not allowing to clear the field/or whatever is entered. Please provide some good solution which will execute in mobile device. Thanks in advance.
