Hi all,
I'm not sure about using the form component correctly, because my
setup ends in a Javascript exception.
Environment:
- Tapestry 5.4-alpha-15
- configuration.add(SymbolConstants.FORM_CLIENT_LOGIC_ENABLED, false);
- tapestry-beanvalidator module using Hibernate Validator 4.3.1.Final
The setup is pretty easy: there is a class RSSChannel with two String
properties, url and name, both @NotNull and there is this basic form:
<t:form t:id="form" validate="rssChannel">
<t:errors />
<div class="form-group">
<t:label for="url">URL</t:label>
<t:textfield t:id="url" value="rssChannel.url" class="form-control" />
</div>
<div class="form-group">
<t:label for="name">Name</t:label>
<t:textfield t:id="name" value="rssChannel.name" class="form-control" />
</div>
<t:submit />
</t:form>
In case one of the fields is empty, the correct validation errors are
reported back to the client, but I get a JS exception while Tapestry
tries to highlight the corresponding text field:
Uncaught TypeError: Object function () { return
wrapElement(document.body); } has no method 'findFirst' (fields.js,
line 20)
Is this a bug? If yes, I will create an issue.
Another question: Is it possible to create plain old HTML forms,
without all the Javascript automagically added by Tapestry? A normal
input tag isn't bound to a page property out of the box. I'm thinking
of creating leaner server-side only form components.
Thanks a lot in advance for all hints!
Thilo
