how to set #{invalid} in action

tynor Jul 18, 2007 3:54 PM

I need to do some extra validation in certain actions -- for failed validation, I can set control-specific error messages in the action method via:

FacesMessages.instance().addToControl("name", new InvalidValue("my error text", MyClass.class, "name", getInstance().getName(), getInstance()));

but I've not figured out how to set the "invalid" state so that the ${invalid} EL function returns true (without setting invalid, my form displays the error messages, but does not highlight the field input controls in red as a normal HibernateValidation error would.

Help? (and thanks)

I've been reading the source (1.2.1-GA), Luke, but am still without enlightenment. In Seam's UIDecorate, I see:

Contexts.getEventContext().set("invalid", hasMessage(this, context));

and hasMessage() appears to search down the child components looking for messages -- the input control has one since in my code, I do the following:

FacesMessages.instance().addToControl("name", new InvalidValue("my error text", MyClass.class, "name", getInstance().getName(), getInstance()));

You would think that my adding the message to the control would be enough for UIDecorate to find it when it goes searching for messages. It doesn't -- the message is rendered in my facelet, but the label and control are not styled as "error" (which is controlled in the edit.xhtml template via the #{invalid} EL expression).

So what else do I need to do to cause the UIDecorate to see the message and set the invalid property??

Just look at the booking example, it is working there.

Thanks Gavin.

In fact, it's _not_ working in the booking example either. Here's the rendered HTML for failed "date must be in the future" message set by the action class:

<span id="booking:checkinDateDecorate">

 <div class="entry"><label class="label " for="booking:checkinDate">Check In Date:<span id="booking:_id57" class="required">*</span></label>
 <span class="input "><input id="booking:checkinDate" name="booking:checkinDate" type="text" value="07/19/2006" onblur="A4J.AJAX.Submit('_viewRoot','booking',event,{'parameters':{'booking:_id61':'booking:_id61'},'actionUrl':'/seam-booking/book.seam'})" /><script type="text/javascript"><!--

var CAL_DAYS_SHORT = 'Su,Mo,Tu,We,Th,Fr,Sa';
var CAL_DAYS_MEDIUM = 'Sun,Mon,Tue,Wed,Thu,Fri,Sat';
var CAL_DAYS_LONG = 'Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday';
var CAL_MONTHS_MEDIUM = 'Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec';
var CAL_MONTHS_LONG = 'January,February,March,April,May,June,July,August,September,October,November,December';
var CAL_FIRST_DAY_OF_WEEK = 0;
var CAL_DATE_FORMAT = 'MM/dd/yyyy';
//--></script><script type="text/javascript" src="/seam-booking/seam/resource/web/date/calendar.js"><!--

//--></script><span onclick="__selectDate('booking:checkinDate', 'booking:checkinDate');"><img src="img/dtpick.gif" style="margin-left:5px;cursor:pointer" /></span>
 </span><span class="error errors">Check in date must be a future date</span>
 </div></span>

Note that the message is properly rendered, but the label and controls do not have the errors class added to their CSS style as the edit.xhtml template intends. (should see <label class="label errors" , but instead just see <label class="label " ).

Um, I dunno, it works perfectly for me in CVS....

OK. I'll set this aside until we can upgrade from 1.2.1 to 2.0. Perhaps this will be magically fixed in the upgrade.
