Quesitont about .repeater.DataTableFilterToolbarPage : mutliple fitered

2016-02-19 Thread andre seame 
Hello,


The repeater.DataTableFilterToolpage 

 demonstrates a unique filter.


My questions are :

- Is it possible to have several sortable columns.

- How to put the 2 sortable fields into the th ? Or Foreach sortable column, I 
would like to add the 2 fields in the associated column.


For instance:


 
   Born datefrom: ...
   Death Datefrom: ...



Thanks,

Re: Wicketstuff editable grid - 7.1.0

2016-02-19 Thread Mihir Chhaya 
Ok, so creating a small project with two panels(Person and Customer) and a
page for similar use case resulted in following stacktrace.
The panels are added in the order of PersonPanel, CustomerPanel in the
parent page.

The line# 163 in onSave method of EditableGrid is calling
EditableGrid.this.onSave(target, rowModel); I wonder if the reference to
this is referring to the first EditableGrid with Person records. Switching
the order of adding grid panels throws the error other way around;
complaining for Person cannot be cast to Customer.

Re: Wicket model problem

2016-02-19 Thread Francois Meillet 
You can also use a IDetachListener to check that no one LDM (field) is attached 
after the page#detach() has been called. 

In the Application#init() you can add

getFrameworkSettings().setDetachListener(

new IDetachListener() {

@Override
public void onDetach(Component component) {

for (Field field : 
component.getClass().getDeclaredFields()) {
field.setAccessible(true);

Class theClass = field.getType();
if 
(LoadableDetachableModel.class.isAssignableFrom(theClass)) {

try {
if (((LoadableDetachableModel) 
field.get(component)).isAttached()) {
System.err.println("warning: component:" + 
component.getClass().getName() + " / " + field.getName() + " is attached");
}
}
//
catch (IllegalAccessException e) {
e.printStackTrace();
}
}
}
}

@Override
public void onDestroyListener() {

}
}
);

Re: Wicketstuff editable grid - 7.1.0

My mistake about the inmethod grid dependency. I don't know why I saw
compilation error in editable grid class when removed inmethod grid jar
from classpath.

For debugging the respond method as your suggestion, I do see correct class
types for each rowItem (as attachment). But it fails with following error:

Last cause: No get method defined for class: class
packagename.ExceptionalDocCode expression: decisionCode
WicketMessage: Exception in rendering component:
[EditableTextFieldCellPanel [Component id = cell]]

Re: Wicket model problem

2016-02-19 Thread Bas Gooren 
Hi,

I think the only way to track this is with custom code (or with aspects for 
example).

Since the contract of IModel only has detach() (and not isDetached()), this 
cannot be tracked easily.

What I would do in such a case is probably to add a requestcyclelistener which 
walks a page after a request, iterates (/visits) over all the components and 
checks their models.
Of course this requires the models to expose a way to check their status and 
origin.

Also, what we do to prevent this: we have an abstract base model called a 
AbstractConversionModel which takes a parent model (S) and converts to a 
target type (T), caching the conversion.
This model takes a parent model as input (and subclasses of it require a java 8 
Function or expose an abstract method for the conversion etc).
This model also takes care of detaching the parent model.

In the end it’s all about education I guess: programmer’s should be careful 
when chaining models and ensure they detach the parent (/chained) model.

Met vriendelijke groet,
Kind regards,

Bas

Thanks for the reply.  I suspect this is exactly the case we have created for
ourselves.  Although we have a good grasp on the detach process I suspect
that there are places where this rule of thumb is not being followed. 
Although the example I gave is somewhat fictitious, any of the LDMs we have
in our framework perform a detach on the parent.  In the form there are
numerous places where adhoc anonymous models are created and this is
probably where the problems occur.  Is there a recommended way to track
these down?  I ended up recompiling a version of Wicket with changes to
LoadableDetachableModel that would essentially track every LDM within a
RequestCycle.  At the end of a request cycle I was left with a list of the
models that never got detached.  I also added a "whereAmI" member variable
to LDM that would capture the stack trace in the constructor so I could
figure out who instantiated the model in the first place.

Re: Wicket model problem

2016-02-19 Thread Bas Gooren 
Hi!

Perhaps this is stating the obvious since it looks like you know what you are 
doing, but just to be sure:

Does your LoadableDetachableExpressionModel call detach on its “parent” model? 
This is the most frequently occurring source of model leaks I have seen.
Since the last model in the chain is usually attached to a component, that 
model gets detached, but if your “child” model does not call detach on the 
“parent” model and the “parent” model is not attached to a component, it will 
never get detached.

Which model in your example is not getting detached without your override of 
onDetach() in MyPanel? Does it happen to be “abc”?

Met vriendelijke groet,
Kind regards,

Bas

// create a panel for DEF object  
Panel subPanel = new SubPanel(def);  
this.add(subPanel);  

// create a model for a repeating list of GHI  
LoadableDetachableModel ghi = new  
LoadableDetachableExpressionModel(abc, "g.h.i");  

// create a repeating section for GHIs  
ListPanel listPanel = new ListPanel("listPanel", ghi) {  
@Override  
public Component createItemComponent(String id, IModel

@Override

}  


This pattern, in our case, seems to end with a bunch of models that never  
get detached. Therefore on subsequent request we end up with some parts of  
the form reattached to the document from the cache and other parts attached  
to orphaned transient models from their unattached models. Then when you  
submit the form the components that are attached to the cached object update  
the correct model object but the ones that didn't get detached properly  
update the orphaned model objects. So we end up with data lose. To get  
this working we changed the MyPanel class to something like this:  

// Panel  
class MyPanel extends Panel {  

private LoadableDetachableModel abc;  
private LoadableDetachableModel def;  
private LoadableDetachableModel ghi;  

void onDetach() {  
abc.detach();  
def.detach();  
ghi.detach();  
}  

MyPanel(final IModel cacheLDM) {  

// create an LDM that uses the cache LDM and an expression  
abc = new LoadableDetachableExpressionModel(cacheLDM, "a.b.c");  

// another one based on abc  
def = new LoadableDetachableExpressionModel(abc, "d.e.f");  

// create a panel for DEF object  
Panel subPanel = new SubPanel(def);  
this.add(subPanel);  

// create a model for a repeating list of GHI

// create a repeating section for GHIs  
ListPanel listPanel = new ListPanel("listPanel", ghi) {  
@Override  
public Component createItemComponent(String id, IModel  
model, Item item) {  
return new GHIPanel(id, model, isReadonly, mode);
