This isn't enough information to enable anyone to help you. You need at the least:

1. product being used and full version

2. indicate how you are triggering validation

3. indicate whether you see a request to the server, and if so, the full server logs for the request

Hi

I am using SmartClient_v91p_2014-07-18_Evaluation for evaluation purpose

When I press the submit order button, nothing happen and ther is nothing in the server.log.

Please advise

Well, the most obvious problem here is that you are binding the DynamicForm to a DataSource that doesn't exist (".._tony").

This sort of error is very easy to troubleshoot using the Developer Console, since prominent warnings are logged.

If you are unfamiliar with how to use the Developer Console, make sure you have read the QuickStart Guide.

**H08849** · 6 Oct 2014, 02:16

Hi

I changed the datasource to validationDMI_orderForm
But is still the same.
The java class is not called and nothing show in the server log.

Please advise.
Many thanks

**Isomorphic** · 6 Oct 2014, 06:28

We have reminded you multiple times to always post the diagnostic information covered in the FAQ.

Please make sure to do this, every time. If we see it is missing yet again, you will not be reminded again.

**H08849** · 6 Oct 2014, 18:11

Hi,

But there was nothing shown in the server log when I press the sybmit order button.
This is the server log starting from thr jsp was loaded.

Please advise

Many thanks
