Validations in Web Dynpro Java

Question

Hello,
I'm trying to create a lot of validations in a web dynpro App.
Examples:
  - An inputfield must not pass 6 characters of length. (I can set the inputfield length of 6 characters but I can't force the inputfield to accept only 6 characters).
- Some fields (inputfield, textEdit, dropdownByKey) are mandatory. (I can see the property state = "required" but I don't know how it works)
- Some field are mandatory depending in a previous selection.
I'm finding that adding this validation logic to the form is very heavy and implies a lot of work. I want to ask if someone knows an easy and automatically way to add this validation logic to the app, or I can't escape of programing everything.
Please help.
Regards
SU

Hi SU,
I wrote the following code just to check if this method works or not. Well, this method does work.
Ceate a message in the message pool and use the following code
IWDNode node = null;
wdControllerAPI.checkAndReportRequiredFields(node ,IMessageNew1Comp.VALIDATION__MESSAGE, new Object[]{"test"});
" in my case the attribute bound to the input - whose state is required - is in root container.
"That's why I am passing null as first parameter.
Validation_Message is the message key
"test" is the message which you could pass to the passholder
I hope it helps.
