Validator, conflicting data types, and spring:bind errors

[tortuga]

I'm very new to Spring and have been using Web Flow PR3 to design a fairly straightforward multi-page form based off of the 'sellitem' sample. I have run into two problems, both of which are related:

The first problem is that <spring:bind ....> tags are not being intercepted in my .jsp files, so I cannot see any errors that are generated by Web Flow. For instance the following .jsp:

<spring&#58;bind path="user.*">
	<c&#58;forEach items="$&#123;status.errorMessages&#125;" var="error">
		Error code&#58; <c&#58;out value="$&#123;error&#125;"/><br/>
	</c&#58;forEach>
</spring&#58;bind>

then becomes the following when output to the web browser:

<spring&#58;bind path="user.*">

</spring&#58;bind>

The second problem is that when I choose a form object that has class members that are not strings, such as a long, when SWF binds to this object, the current state (page) of the flow is returned again if the field is left blank, or un-convertable data is entered (such as a ',' for a long data field). I know that an error is returned because if I enter in a number, the flow continues to the next state (page). However, as i mentioned in my first problem, I can't see this error since <spring:bind ...> tags are not getting interpreted.

The most irritating problem is that if a field is not required, but should be something other than String, then I will have no way of ignoring empty fields! Obviously if a ',' was entered I would like to reply, but otherwise if the field is empty it should be inherently ignored.

Regardless, here's my code:

Sorry for so much code, but I'd rather provide more than less.

Thanks for any help!
