How to catch Freemarker exceptions (the ugly big yellow pages)
FreeMarker delegates exception handling to so-called TemplateExceptionHandlers. By default the HTML_DEBUG_HANDLER is used (this one generates the yellow error page), but you can easily specify a different exception handler by using the setTemplateExceptionHandler method of your configuration object. FM provides some simple handlers you can use, in your case I recommend the RETHROW_HANDLER (
http://freemarker.org/docs/api/freemarker/template/TemplateExceptionHandler.html).

How to disable validation on the first page load (to show a in input form)?
If you define your own stack you can exclude methods from validation by adding the excludeMethods param to both Validation and Workflow.

How to disable validation on any given method?
use
@SkipValidation tag on the method.
ex:
| Code Block |
|---|
@SkipValidation
public String logout() {...}

When using clientside validation, DWR states it gets No Data From Server
When using firefox if a user has focus on an input control and then clicks the submit button i get a DWR error stating that there was no data from the server.
I searched around on this group and did not see a solution. Via the DWR mailing list I found a post fromi Joe Walker stating that a workaround was to register a custom DWR error handler ..

Why can't I use && (=and) in my validation rules ? || (=or) does work !
You can't use && directly since the validation files have to be wellformed xml. The correct syntax would be & ;& ; (without the spaces)
