Re: Custom Component Id Other than Class Name
If you knew what you were doing, you could decorate the ComponentClassResolver.

Re: Custom Component Id Other than Class Name
I guess it's possible that you put components into different "virtual folders"/packages and then make different library mapping names for them. http://tapestry.apache.org/component-libraries.html#ComponentLibraries-Step4%3AConfigurethevirtualfolder Cheers, Dragan Sahpaski On Sun, Oct 14, 2012 at 12:04 AM, Bob Obringer wrote: > I've created a library of custom Tapestry components and have been unable to > figure out how to use an ID other than class name to reference those > components. > > The library I'm creating is part of a much larger framework and as such I > have requirements for class names.

Re: Custom Component - @BeforeRenderBody not rendering stuff
Thanks
My "source" (and whatever the iterator returns) are always null...so I'll have
to find out why that happens.

Re: Custom component
yes, the second is better If your component is a "container" for a group of fields. In that case, you should do it in the afterRender phase, so your method is called after all single fields has already the new submitted values and you can "validate" (and rollback if you want) the whole result. 2011/10/3 Rendy Tapestry > Thanks Taha, > > I'll give your second suggestion a try. > > Thanks, > Rendy. > > On Sun, Oct 2, 2011 at 11:03 PM, Taha Hafeez Siddiqi < > tawus.tapes...@gmail.com> wrote: > > > Hi Rendy > > > > Your component, if fits the definition of a form field, can extend > > AbstractField and then override processSubmission() method. > > > > Otherwise you can @Inject FormSupport and then use > > FormSupport#storeAndExecute() to execute a ComponentAction > > > > regards > > Taha > > > > On Oct 2, 2011, at 9:18 PM, Rendy Tapestry wrote: > > > > > Hi All, > > > > > > Is it possible to have a custom component with a method that will > getting > > > called when the enclosing form is being submitted ?

Re: Custom component
Hi Rendy Your component, if fits the definition of a form field, can extend AbstractField and then override processSubmission() method. Otherwise you can @Inject FormSupport and then use FormSupport#storeAndExecute() to execute a ComponentAction regards Taha On Oct 2, 2011, at 9:18 PM, Rendy Tapestry wrote: > Hi All, > > Is it possible to have a custom component with a method that will getting > called when the enclosing form is being submitted ?

I can create a new form component re-using other form components -

To read the template I yanked code out of the BaseComponent class.

I plowed ahead with trying to implement my own AbstractFormComponent that
would use an html template and also render some of its own content. However, I
am getting a stale link exception when I submit. Either I am setting something
up incorrectly or missing the boat on the rewind. Not exactly sure how to parse
the StaleLink page. Been diving through the list archives and source trying to
get a better idea on how component ids are generated and the rewind is done.
I can create a new form component re-using other form components - right?
To read the template I yanked code out of the BaseComponent class.
In the end, I want my custom component to display a checkbox and a textfield
(possibly a PropertySelection as well). When the form is submitted, if the
checkbox is checked but no content is contained in the textfield I want to
decorate it and add a message to the top. This component will be used at least
a dozen time on the page for different search parameters.
Gradually learning!
Thanks,
Ryan
Exception:

You have clicked on a stale link.
Rewind of form test/testForm expected 1 more form elements, starting with id
'selected'.
This is most likely the result of using your browser's back button, but can
also be an application error.

RE: Custom component validation - two fields
What we do is to wrap the checkbox in an AnySubmit. And then when checked a submit happens and the field is then displayed with whatever mark-up is required. If the user attempts to leave the screen standard edits tell them they need to provide a value. If they uncheck the box, the field goes away. Basically, it is done via a Conditional or Choose Component. hth, Mark -Original Message- From: Ryan Cuprak [mailto:[EMAIL PROTECTED] Sent: Fri 6/2/2006 12:38 PM To: users@tapestry.apache.org Subject: Custom component validation - two fields Hello, We are trying to implement a rather simple custom form component for a search page and perform validation on it. The custom component has a checkbox and a text field. If the checkbox is checked then a value must be provided in the text field. If not, the field must be decorated and a message displayed at the top of the form (tie in with the delegate etc). What is the recommended approach for implementing such component validation? Must we extend AbstractFormComponent and implement the renderFormComponent or is there a simpler approach? Is there a hybrid AbstractFormComponent/BaseComponent we have missed somehow? Thanks!
