tapestry hibernate integration NPE
Hi All! I detected a bug(?) in the HibernateEntityValueEncoder. When the hibernate entity's primary key contains an underscore in the primary key member name like private Long _pk; than the HibernateValueEncoder fails with: Caused by: java.lang.NullPointerException at org.apache.tapestry5.internal.hibernate.HibernateEntityValueEncoder.toClient(HibernateEntityValueEncoder.java:59) at org.apache.tapestry5.corelib.components.Loop.begin(Loop.java:396) at org.apache.tapestry5.corelib.components.Loop.beginRender(Loop.java) at org.apache.tapestry5.internal.structure.ComponentPageElementImpl$BeginRenderPhase.invokeComponent(ComponentPageElementImpl.java:202) at org.apache.tapestry5.internal.structure.ComponentPageElementImpl$AbstractPhase.invoke(ComponentPageElementImpl.java:143) because the propertyAdapter.get method returns null for the given entity instance. The root cause for this is here (HibernateValueEncoder:51): propertyAdapter = propertyAccess.getAdapter(this.entityClass).getPropertyAdapter(property.getName()); as property.getName returns _pk which is not in the list of adapters, but pk is... The easy work around is just to rename all my pk fields, but as Tapestry is happy with leading underscores the hibernate integration should be too? Is there something wrong on my side or shall I fill a jira? Jens - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Autocomplete gotT5
Hi All!
I have two questions concerning jquery/autocomplete and hopefully one of
you can point me to the right direction.
Part 1:
Basically everything is working fine: onProvideCompletions is called and
the list is displayed. Unfortunately I need to render a different href
and text in the a element. So while returning ListString
autocomplete does the job well, I noticed the plugin supports
JSONObjects, too.
Therefore I tried to return
ListJSONObject onProvideCompletions()
to return a different label and value.
Idea borrowed from stack overflow:
http://stackoverflow.com/questions/4536055/jquery-autocomplete-where-the-results-are-links
Thus building the object looks like:
final ListJSONObject results = new
ArrayListJSONObject(MAX_RESULT_SIZE);
for (...) {
results.add(new JSONObject().put(value,
linkUrl).put(label, linkTitle));
}
This results in
{
value : http://localhost:8080/demo/url;,
label : this is the label for demo-url
}
But only the label is rendered, still. Any hint how to change the
rendering og a is welcome.
Part 2:
Is it possible to update a zone due to an autocomplete callback?
Thanks in advance
Jens

onActivate UnknownValueException
Hi All! I use an enum as activation context parameter. Unfortunately in case the enum changes or more likely the user has a typo in the url Tapestry is unable to coerce the url param to enum and fails by throwing an exception (fair enough). Instead of using onActivate parameters I switched to EventContext to get fine grained control here by simply catching the exception when coercing the enum from a given event context value. I wonder if there es a more elegant solution currently build in? If not what do you think about: a) can't we create a new Tapestry annotation like CoerceExceptionDefaultsToNull or something similar to allow this annotation for parameters in onActivate (I know we can not limit it to onActivate, but...) and supress the original exception (maybe not that developer friendly). This introduces if (null == xyz) cascades but at least we won't see an exception at the client side. or b) a callback like Object onActivationCoercionError(final Object value, final Class destinationClass, final Exception e) to make the developer aware of problems, allow providing a default value and Tapestry continues normally by calling the best fitting onActivate method afterwards? Maybe EventContext is the route to go for proper error handling, but my gut feeling is we are loosing much of Tapestry's onActivation magic. Any thoughts?
