T5 - Cancelling a form
What is the recommended way to handle a Cancel button on a form? The
expected behaviour would be to clear the internal state, bypass
validation and move to a different page. I tried:
@OnEvent(component=Cancel)
String onCancel()
{
surveySession.setSurvey(null);
return Start;
}
where Cancel is the id of the submit component but Tapestry
complains that this method cannot return a String:
Event 'selected' from org.byteberry.survey.pages.SurveyDetail:cancel
received an event handler method return value of Start from
org.byteberry.survey.pages.SurveyDetail.onCancel() (at
SurveyDetail.java:46). This type of event does not support return
values from event handler methods.
On the other hand, if I try do do it on the form events I don't know
which button was pressed and I cannot bypass validation.
Is there a straightforward way to do it?
Thanks,
Bogdan Calmac.

Re: T5 - Cancelling a form
There was a discussion last week on the same topic. Howard said that the
best way was to keep a flag like cancelSelected and turn it on on the
selected event. Then in the form submit event look to it and do what it
needs to do.
I think that it is very incovenient, it's a common use case having a lot of
buttons, there should be a way to make events from submits button act like
listeners in tap4, so they are called at last, when all the form has been
processed, so it can redirect to another page.

Re: problem with mvn jetty:run from T5 tutorial
This issue has been driving me crazy, right when I've started with a new client and don't have spare cycles to look into it. I suspect there's an alpha version of some critical Maven plugin that Tapestry is picking up by mistake. The right solution is probably to go find the offending plugin and nail down the version to something stable, rather than latest snapshot.

Re: T5 - Cancelling a form
How about a:actionlink t:id=cancelcancel/a ? Why should it be necessary to do a form submission, just to discard all the data in the form? If you want, you can use CSS to dress up the link to look like a form submit button. I think having this cancel feature in T4 was a mistake that caused more problems than it solved.

Re: T5: Customizing generation of client id from component id
Have you thought about using a specialized class value for links etc. that are going to be involved in the test suite, and then selecting by class instead of id? Just an idea ... On 3/23/07, Doug Hauge [EMAIL PROTECTED] wrote: Thanks for the response. We are in the process of migrating our application to Tapestry, and in the process making it more easily customizable and testable. The solution we are looking for seems to be a reasonable way to satisfy the following constraints: 1) Within a component, identifiers given to sub-components should be as simple as possible while being descriptive. For most components, little thought should be required about what other components might appear in the page. 2) Within a page, components should be able to be rearranged, added, and removed without affecting the identifier given to the associated element(s) in the rendered HTML. Such an immutable identifier is useful for Selenium tests that are valid across such page modifications. 3) In keeping with the DRY principle, we would like to avoid requiring a mixin or other boilerplate code to be included in all our components in order to construct unique identifiers. The problem is that (1) can easily lead to a case where multiple components specify the same component id for their children, because the component writer has no knowledge of what other components may be placed in the page, and in order to keep the component id simple we don't want to require the component writer to always apply a prefix to increase the likelihood of uniqueness. All that we want to require of the component writer is that within the component, all the identifiers are unique. There might also be cases where the same component is included multiple times within a page, either directly or indirectly. Note that an ideal solution for us would also allow us to similarly transform id attributes on HTML elements in the template. If we can't, we either have to avoid specifying identifiers on raw HTML elements or to make sure that all components that may ever be placed on a page choose identifiers that are unique among those components. We have a temporary solution now that uses a mixin that traverses the DOM and adjusts identifiers in its 'afterRender' method, but this violates (3) and is a bit of a kludge.

On 3/23/07, Doug Hauge [EMAIL PROTECTED] wrote: Is there a way to customize the generation of a unique client id from a component id? We would like to generate the unique id in such a way that it would not change across most modifications to a page, mainly so Selenium tests can be written that will work across page redesign. The current method of appending a suffix to a component id does not seem to allow this, so we would like to be able to generate a unique id by prepending the component ids of ancestral components. We could potentially implement our own PageRenderSupport service, but the 'allocateClientId' method only takes a string parameter, so we don't have the context we would need (in particular, the ComponentResources of the component for which we are generating the id).

Re: T5: No /option tag rendered when using enum
This is correct behavior for rendering HTML (as opposed to XHTML).
Unlike T4, T5 knows the difference. HTML is a SGML language where
open tags are not necessarly balanced with close tags.
What's coming is the ability for Tapestry to render XML/XHTML
correctly and choose the correct strategy (HTML vs. XML/XHTML)
automatically.
On 3/22/07, Erik Johansson [EMAIL PROTECTED] wrote:
Hi,
when using the Select component with an Enum the options within the select tag wont
render the /option tag.
Example:
The enum
public enum TestEnum {
ONE,TWO,THREE;
}
will render the select
select id=selected name=selected
option value=ONEOne
option value=TWOTwo
option selected=selected value=THREEThree
/select
Is this a known bug? (I'm not familiar with JIRA so I dont know how to post
this or if it has been noticed)

Re: required fields formatting BEFORE validation
Yep.
On 3/23/07, Martino Piccinato [EMAIL PROTECTED] wrote:
Ok,
I reply to myself hoping this would be of any help for somebody else.
Is as simple as to make your own IValidationDelegate and override (exemple)
this method:
public void writeAttributes(IMarkupWriter writer, IRequestCycle cycle,
IFormComponent component, IValidator validator) {
// If the form component represents a required field
// it adds the required field class
super.writeAttributes(writer, cycle,component, validator);
if (component.isRequired()) {
writer.appendAttribute(class, requiredField);
}
}
obviously then you have to use your IValidationDelegate in your
pages/components.

It's always a good thing for users to know compulsory fields before

I know the issue is easy to solve just by adding few things but it would
be good to have this in componentes that accept required validator.
