My form error message, include link to a page from java class
Hi Tapestry Users,
What is the best way to include a link to a page from the java class?
I have a form, returning an error that states: "The ip address you entered
is public and in use - please try again or search for it to see it's
current use"
I would like to put a link in that error message to the search page.
It's just a standard form.recordErrors
form.recordError(commonNameField, "The ip address you
entered is public and in use - please try again or search (PUT LINK HERE TO
SEARCH PAGE) for it to see it's current use");
Cheers
Chris

The only place Tapestry does expansions is in templates and a couple
annotations involving symbol values. But the expansion above would be
wrong anyway and fail with an exception.

Nope. I vaguely recall a JIRA issue asking for Form.recordError() (which
actually delegates to ValidationTracker.recordError()) to accept HTML and
not encode it.

Beauty, I'll give that a shot - sounds like what I want to do.

Re: My form error message, include link to a page from java class
Posted by Taha Siddiqi <ta...@gmail.com>.
Oops! Sorry I misunderstood your question.
If you want a clickable link, I don't think Errors component can do that.
http://tapestry.apache.org/5.3/apidocs/src-html/org/apache/tapestry5/corelib/components/Errors.html
The text message is written as writer.write() rather than writer.writeRaw()
You can create a new component for errors by copying the code from Errors and using writer.writeRaw
http://tapestry.apache.org/5.3.7/apidocs/org/apache/tapestry5/MarkupWriter.html#writeRaw(java.lang.String)
then you can pass html string to form.recordError()
"<a href='" + link.toAbsoluteURI() + "'>here</a>"

Re: My form error message, include link to a page from java class

Thanks, but no again.
form.recordError(commonNameField, "The ip address you entered is public and
in use - please try again or search for it ${" + link.toAbsoluteURI() + "}"
);
renders this as a string, and without the expansion-y ${} it's just plain
old text.
${http://hplaptop:8080/MetwideSubnetsWeb/search/ipaddress}
Similarly putting an <a href=\" + Link#toAbsoluteURI + \">blah</a> just
outputs text, like this:
<a href="${http://hplaptop:8080/MetwideSubnetsWeb/search/ipaddress}">
blah</a>
(I've copy pasted html src. In case it's not viewable, tapestry has
converted the less than and greater than in the previous sentence to
ampersand+elle+tee+semi-colon and ampersand+gee+tee+semi-colon,
respectively)
Form#recordError accepts a String. So I'm starting to think this String is
just rendered without any smarts to it. Can't really fuse in a
MarkupWriter, because recordError just accepts String.
Any further ideas?
Can the Corelib.Errors component, rather than just being
<t:errors />
be expanded to hold a <t:if> and ${expansion} for use in case of error?
Cheers

Use Link#toAbsoluteURI() or Link#toURI() depending on your need( I think here toAbsoluteURI() is more appropriate)

Re: My form error message, include link to a page from java class
Posted by Chris Mylonas <ch...@opencsta.org>.
Thanks Taha - I was looking at the Link Component FAQ earlier scratching my
head. It spits out the text for the link, not a html link.
So I tried this:
Link link = linkSource.createPageRenderLink(IPAddress.class);
if (ni != null) {
form.recordError(commonNameField, "The ip address you
entered is public and in use - please try again or search for it <a
href=\"" + link + "\">HERE</a>" );
}
and that just spits out text too.
Given it's 2am, I'm going to bed. Try again tomorrow with a fresh head.
Cheers,
Chris

Re: My form error message, include link to a page from java class

You can use
http://tapestry.apache.org/5.3/apidocs/org/apache/tapestry5/services/PageRenderLinkSource.html#createPageRenderLink(java.lang.Class)
@Inject
private PageRenderLinkSource linkSource
form.recordError(someField, "my link is " + linkSource.createPageRenderLink(MyPage.class));
there are other variants of createPageRenderLink which can take context parameters.
