RE: how to use HibernateEntityValueEncoder

[Ken in Nashua]

Joakim,
 
Thank you for the suggestion.
 
I was hoping for checkins on the framework I use but non yet. I am stuck until 
that happens.
 
But I can unit test while stuck.
 
I will try your suggestion... making a get/set displayableString() and just put 
toString() inside of it.
 
The tapestry framework should consider using toString as the default for 
objects populating select and contained options by default.
 
I will let you know the result.
 
Have a good day friend
Ken
  

RE: how to use HibernateEntityValueEncoder

[Ken in Nashua]

Hey Joakim...

I tried your suggestion... and it worked.

I actually created an interface with a host of default methods that I am 
forcing down the hierarchy... one of which is displayableName.

And I made it past the tapestry code...

final PropertyAdapter propertyAdapter = 
classPropertyAdapter.getPropertyAdapter(labelProperty);

final ValueEncoder encoder = 
this.valueEncoderSource.getValueEncoder(propertyAdapter.getType());


propertyAdapter is not null anymore... and so I am able to get my encoder 
successfully now.

Thanks a bunch...

- ciao

KEN

RE: how to use HibernateEntityValueEncoder

[Ken in Nashua]

So it sounds like... 

I need to implement an auxillary property called 
getDisplayableName/setDisplayableName in order for this to make it into the 
options construct's.
 for EVERY class I intend to populate into any select.

toString is the default displayable for any object 
i vote for that to be the default instead 

Thanks for pointing that out for me Thiago.

If I can get my webapp to run then i will test it out and maybe implement my 
own SelectModelFactoryImpl

- cheers

Just if you don't have a property which already provides what you want.  
Most of my entity classes have a name field and property that could be  
used already. Of course, whether this is sufficient of enough is very  
dependent on the specific scenario. And you actually need just the getter.  
And this is actually pretty standard Java stuff.

Of course Tapestry cannot find the toString property. As Joakim said,  
toString() is not a property. It's a method, but not a property.  
Properties are defined by get and set methods. That's basic Java knowledge.

RE: how to use HibernateEntityValueEncoder

[Ken in Nashua]

Thanks Joakim... for trying

I tried to get a clean head rev build off my framework providers but its never 
had a clean head rev build ever (months and years) and I have been very quiet 
about it limping along waiting for pristine code. They seem to be under the 
impression that everything just works and tooting their horns on the framework 
site... when it dont... otherwise I would have been long gone spent busying 
myself focusing on business logic instead of build problems, codebase 
corruption code base instrumentation to overcome issues.

So I am going to SHcan my attempt at getting a clean fresh build to eliminate 
these problems and revert back to the buggy code base I have been wrestling 
with. But if that worked I would have been focusing on business logic still.

I will give your suggestion a try.

I have been known to be a big mouth or sometimes a bad mouth about open source. 
At least when I was a committer I maintained a clean and tight head rev build 
and was always QA'ing the base line functionality to avoid any road blocks or 
show stoppers for users potentially waiting to go live.
Thanks friend

RE: how to use HibernateEntityValueEncoder

[Ken in Nashua]

Hi Guys,

really sorry about my lapse here in providing the right info and I kow it must 
be frustrating.

I played hockey last night. So i got pre-empted.

Ok I am back on the tarp.

I will try to get the stack trace for you... but none is being produced in the 
console... and its an NPE ? I am wondering about that.

My Year.Java class... yes its a pojo... I dont understand why that might be a 
crime... maybe for Date stuff... but its fairly remote and implemented 
independent.

Ok back to he real stuff...

Ok I am seeinfg the source code for this has tajken on some changes,,,

Here is my blip

@Inject
@Property
private TypeCoercer typeCoercer;

@Property
private SelectModel yearSelectModel;
@Property
@Persist(PersistenceConstants.FLASH)
private Year year;

@Inject
private PropertyAccess adapter;
@Inject
private ValueEncoderSource valueEncoderSource;

@SetupRender
void setupRender() {

SelectModelFactory selectModelFactory = new 
SelectModelFactoryImpl(adapter, valueEncoderSource);
grid.reset();

years = new 
ArrayList(TynamoUTIL.loadCollection(hibernatePersistenceService, Year.class));
yearSelectModel = selectModelFactory.create(years, toString);

selectModelFactory is failing because my usage of SelectModelFactoryImpl fails 
to operate. So I told eclipse to connect to the source code downloaded to my 
local repo... and sure enough.. in the debugger I see this...

final PropertyAdapter propertyAdapter = 
classPropertyAdapter.getPropertyAdapter(labelProperty);

final ValueEncoder encoder = 
this.valueEncoderSource.getValueEncoder(propertyAdapter.getType());


my propertyAdapter is null and any subsequent attempts to use it fail with NPE

But I need to distinguish some kind of label property ? in my year class to 
this thing ? So it can create the proper OPTIONS eFrastructure ?

I figured the Year.toString() method would suffice for this.

Here is my Year.JAVA again

Not sure what to think... tapestry is failing when I tell it to use 
Year.toString()

What should I do ?

@Entity
@ClassDescriptor(hasCyclicRelationships = true, nonVisual = false)
public class Year implements Cloneable, Serializable {
private static final Log log = LogFactory.getLog(Year.class);

private Integer id = null;

private Integer yearStart = new Integer(0);

private Long created = new Long(GregorianCalendar.getInstance()
.getTimeInMillis());

private Long accessed = new Long(GregorianCalendar.getInstance()
.getTimeInMillis());

} catch (Exception e) {

e.printStackTrace();
}
}

}

}

return yearEnd;
}

@ManyToOne
public League getLeague() {
return league;
}

@PropertyDescriptor(nonVisual = true, searchable = false)
public Long getCreated() {
return created;
}

@PropertyDescriptor(nonVisual = true, searchable = false)
public Long getAccessed() {
return accessed;
}

@Transient
@PropertyDescriptor(nonVisual = true, searchable = false)
public String getCreatedAsString() {
Calendar cal = new GregorianCalendar();
cal.setTimeInMillis(created.longValue());
return DatePattern.sdf.format(cal.getTime());
}

@Transient
@PropertyDescriptor(nonVisual = true, searchable = false)
public String getAccessedAsString() {
Calendar cal = new GregorianCalendar();
cal.setTimeInMillis(accessed.longValue());
return DatePattern.sdf.format(cal.getTime());
}

public void setId(Integer id) {
this.id = id;
}

public void setYearStart(Integer yearStart) {
this.yearStart = yearStart;
}

public void setYearEnd(Integer yearEnd) {

RE: how to use HibernateEntityValueEncoder

[Ken in Nashua]

Ok I am stepping thru the tapestry code during the create call...

This is interesting...

UnClaimedFieldWorker.JAVA
public Object get(Object instance, InstanceContext context)
{
return fieldValue.get(fieldDefaultValue);
}

fieldDefaultvalue == null

no npe as of yet

its starts iterating thru my obejct list looks good so far

I am at this line in SelectModelFactoryImpl.JAVA

final PropertyAdapter propertyAdapter =
classPropertyAdapter.getPropertyAdapter(labelProperty);

this is what I see for classPropertyAdapter
ClassPropertyAdaptor org.tynamo.examples.pphl.model.Year : accessed, 
accessedAsString, class, created, createdAsString, id, league, yearEnd, 
yearStart

WHY ISNT THE toString method in this ? it is a legitimate property... yes ?

Anyway I specified my labelProperty to be toString which should be the 
default by common sense?

propertyAdapter keeps coming back with NULL.

What can I do to my Year.JAVA to make this work ?

Thanks for your help guys
  

RE: how to use HibernateEntityValueEncoder

[Ken in Nashua]

This guy is the culprit... tap-5.3.6

I believe it needs to depend on a default toString() is it fails to find a 
labelProperty.

I need a workaround folks... so waiting on your best.

thanks

KEN

RE: how to use HibernateEntityValueEncoder

[Ken in Nashua]

Hi Jens,

I posted the pojo bean Year.java

I really rely on the toString() for most of my entities.

I wouldnt think of complicating any of my getters with dashes or underscores 
let alone complicate a primary keye method.

This one is fairly obvious.

I know I have some environment concerns and need o sync up with greatest/latest 
tynamo but for the most part my webapp is running.

Hoping for a way out of this one today.

What if I had a dozen select criteria components on my page ?

Well i do... 

: (

I am trying to model stats just like NHL.com

  

Re: how to use HibernateEntityValueEncoder

What could really help us in helping you was if you told us in which line  
the NPE happens. It's really quite hard to help you sometimes. You post a  
lot of messages and still doesn't provide us the information needed to  
help you. :(

Nobody ever suggested you did that. Someone just mentioned that leading  
underscores are not handled well by PropertyAdapter so you could check if  
that was the case.

RE: how to use HibernateEntityValueEncoder

Thanks Thiago... trust me I would send a console trace if I got one. Maybe my 
logger isnt tracing those packages in tapestry ? 

The NPE occurs inside (well i sent the browser trace)... 

org.tynamo.examples.pphl.pages.Query)org.apache.tapestry5.ioc.internal.util.TapestryExceptionjava.lang.NullPointerExceptionFilter
 stack frames
Stack trace

org.apache.tapestry5.internal.services.SelectModelFactoryImpl.create(SelectModelFactoryImpl.java:55)

Its happening inside the create call 

tapestry cannot articulate the labelProperty

I specified toString

I put this in the threads few threads back.

I appreciate your help

And no I am not using any dashes or underscores in the primary keye method... 

Still hoping for a workaround

  

Re: how to use HibernateEntityValueEncoder

[Joakim Olsson]

What if you add a getDisplayString-method that just do return toString()
and change to displayString as property instead. toString does not follow
the bean property naming standard get/set/is.

HibernateEntityValueEncoder is used automatically. All you need to do is  
to have tapestry-hibernate in your classpath. For populating Select's  
model parameter, you can use the SelectModelFactory service.

In case you exclusively want to get the encoder, you can inject 
ComponentDefaultProvider and then use

http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/ComponentDefaultProvider.html#defaultValueEncoder(java.lang.String,
 org.apache.tapestry5.ComponentResources)

Re: how to use HibernateEntityValueEncoder

[mailingl...@j-b-s.de]

Hi Ken!

Just a shot in the dark:
Are you sure the PKs of your hibernate  beans are not null (maybe you have a  
newly created bean instance which is not persited yet)? Afair the 
HibernateValueEncoder requires properly filled PK fields otherwise 
pk.toString() fails. Unfortunately the stacktrace is difficult to read...

RE: how to use HibernateEntityValueEncoder

[Ken in Nashua]

Thanks Jens...

I just stepped thru debugger...

@SetupRender
void setupRender() {
grid.reset();

years = new 
ArrayList(TynamoUTIL.loadCollection(hibernatePersistenceService, Year.class));
yearValueEncoder = new EnumValueEncoder(typeCoercer, Year.class);
 
this is what the debugger shows for my years collection after loadCollection 
gets called.
[2012/2013]

Thats an entity... Year.class... the toString method

So the collection is populating properly. Its stored with standard hibernate 
Integer id.

Kinda blue in the face... kinda
  

RE: how to use HibernateEntityValueEncoder

Ooops... this is the code I am exercising...

@Persist

private EnumValueEncoder yearValueEncoder;
@Inject
@Property
private TypeCoercer typeCoercer;
@Inject
private SelectModelFactory selectModelFactory;
@Property
private SelectModel yearSelectModel;

@SetupRender
void setupRender() {
grid.reset();

years = new

yearValueEncoder = new EnumValueEncoder(typeCoercer, Year.class);
yearSelectModel = selectModelFactory.create(years, year);

  

RE: how to use HibernateEntityValueEncoder

[Ken in Nashua]

Thanks Jens...

I believe I posted the Year.class for Thiago

the primary keye is just ID

Is this a bug ?

I would like to get into the create routine for the factory but dont know how

its obviously happening on the valueencoder

final PropertyAdapter propertyAdapter =

ValueEncoder encoder = 
this.valueEncoderSource.getValueEncoder(propertyAdapter.getType());56

I changed the property method to toString() and it still fails with NPE


  

Re: how to use HibernateEntityValueEncoder

[Jens Breitenstein]

Hi Ken,

please paste the whole Bean class, too. I got an NPE in the past due to 
an leading underscore in my pk member name.

_pk -- NPE
pk -- works fine. Guess this is  a bug, because Tapestry in general 
is happy with _ when accessing properties.
