s:validate and facelets tag (source) file

[pmuir]

Hi

I'm just experimenting with the <s:validate> validator component provided as part of the seam-ui library. The code checks to see that a valid value attribute by looking for a value attribute of

{model.field}

and determines the model from that by stripping off the .field part.

My problem is that I've passed the value to the tag source file as a atttribute e.g.

test-tag.xhtml

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
 xmlns:ui="http://java.sun.com/jsf/facelets"
 xmlns:h="http://java.sun.com/jsf/html"
 xmlns:s="http://jboss.com/products/seam/taglib"
 >
 <h:inputText value="#{value}">
 <s:validate />
 </h:inputText>
</ui:composition>

test.xhtml

...
<my:test-tag value="#{model.field}" />
...

which causes the <s:validate> to throw a runtime exception as the attribute is not an value binding.

Anyone had a similar problem; any suggestions on how to get this to work?

I think the original design of s:validate let you specify the property name. It doesn't seem to be there now. I wonder why it was removed.

If all we have is the attribute value, there is no way to figure out the class of the owning object, and what validations should be applied.

Would you accept/consider a patch to allow

<s:validate property="model.field" />

where property could be a static value or EL that evaluated to a String. The property attribute version would need to take precedence over the value attribute for working out model.field.

Or should I maintain myself?

In case anyone else finds it useful I've put my solution here:

I did a fairly simple modification to the Seam code and added a handler to accomodate EL expressions for the property attribute

Mr Muir,

Have you the latest version of this component?

Thanks,
