Adding new data to existing ListView

[avchavan]

Is it possible to add data to an existing ListView for which data is already
loaded?
Basically what i want is if say i have 10 records already present then add
10 more records to the existing ListView, so we get 20 records.
I tried but the ListView gets refreshed if i try to set the new list to it.

Thanks.

Hi,

Yes, just put more items to its backing List. Or better use an IModel that
fetches the List dynamically based on some conditions.
You need to repaint/refresh it to be able to render the new items. If you
use Ajax then you have to repaint its (grand)parent.

"Marker" view model

[Martin Grigorov]

Hi,

I tried to use a "marker" view model, i.e. a view model without any
properties.
I need it to trigger instantiation of a custom component(factory).
I thought that I may put all the "properties" in the component, so the view
model won't need to have them. It will be just a marker, like marker
interfaces.
This didn't work because of the code at
https://github.com/apache/isis/blob/master/core/viewer-wicket/ui/src/main/java/org/apache/isis/viewer/wicket/ui/pages/entity/EntityPage.java#L124
I will put the properties in the view model to overcome this check.
Is this something that could be relaxed or this check has to stay there for
some other functionality ?

PDF viewed in panel via ResourceReference works in 6.12 but not in 6.13

[Bruce Lombardi]

I have a PdfViewer page that contains a panel that displays a dynamically
generated PDF using a resource reference. This works fine in Wicket 6.12.0,
but when I upgrade to 6.13.0 it stops working (just changed Maven dependency
- no code changes). No errors are displayed and the html is generated
exactly as it is with 6.12, but the pdf does not show up in the page.

By setting a breakpoint in Eclipse I have determined that code in the
resource that produces the response (newResourceResponse) is never called in
6.13. After migrating to the latest version (6.19) I still get the problem.
I've looked at the release notes for version 6.13 and see some changes
related to IResource but nothing that looks related to this problem.

I'm hoping someone has seen something similar. Here is some of the relevant
code:

PdfViewer .html - just has reference to panel

   

 

PdfPane.html - just has object reference

Raw HTML

   

 

Generated HTML - seen with view source in browser



 

PdfPanel.java - has setup for resource reference

public class PdfPanel extends Panel {

   

   private static final long serialVersionUID = 1L;

 

   public PdfPanel(String id) {

  super(id);

  

  ResourceReference resourceReference = new ResourceReference(

   "pdfProducer") {

 private static final long serialVersionUID = 1L;

 

 @Override

 public IResource getResource() {

   WebDocsSession session =
(WebDocsSession)getSession();

 

   final byte[] pdf = session.getPdf();

   

   if(pdf == null)

System.out.println("PdfPanel session.getPdf returned null");

 

PdfResourceProducer pdfResourceProducer = 

new PdfResourceProducer(pdf);

 

   return pdfResourceProducer;

 }

  };



String url = (String)RequestCycle.get().urlFor(resourceReference,
null);

  

MarkupContainer wmc = new WebMarkupContainer("pdf");

wmc.add(new AttributeModifier("data", url));

add(wmc);

   }

 

PdfProducer.java - implements the Resource

public class PdfResourceProducer extends AbstractResource {

 

   private static final long serialVersionUID = -2245331056747467763L;

   final byte[] pdfByteArray;

 

 

   public PdfResourceProducer(byte[] pdfByteArray) {

  super();

  this.pdfByteArray = pdfByteArray;

  if(pdfByteArray == null) {

 System.out.println("PdfResourceProducer constructor
called with

null byte array.");

  }

   }

 

   @Override

   protected ResourceResponse newResourceResponse(Attributes attributes)
{

  ResourceResponse resourceResponse = new ResourceResponse();

  resourceResponse.setContentType("application/pdf");

  // resourceResponse.setTextEncoding("utf-8");

 

  resourceResponse.setContentLength((int)pdfByteArray.length);

  

  resourceResponse.disableCaching(); //do not allow resource to
be cached.

 

  resourceResponse.setWriteCallback(new WriteCallback() {

 @Override

 public void writeData(Attributes attributes) throws
IOException {

   try {

  OutputStream outputStream =
attributes.getResponse()

.getOutputStream();

  outputStream.write(pdfByteArray);

  outputStream.flush();

   } catch (IOException e) {

  throw new WicketRuntimeException(

"Problems writing pdf to
response...");

   }

 }

  });

 

  return resourceResponse;

   }

Re: PDF viewed in panel via ResourceReference works in 6.12 but not in 6.13

[Martin Grigorov]

Hi,

I think I see what happens.
The ResRef is created as a local variable to create the url and then
discarded.
Wicket has something called ResourceReferenceRegistry. When a ResRef is
used to create an url to it it is automatically registered in the registry.
It seems after 6.13 there is no such auto-registration for your ResRef for
some reason.
You should have some WARNs in the logs.

I see nothing component specific in your ResRef so I'd #mountResource() it.
This way it will be always available.

RE: PDF viewed in panel via ResourceReference works in 6.12 but not in 6.13

[Bruce Lombardi]

Thanks Martin. 

I'm not getting any WARN messages in the logs. 
I'll take a look at mounting the resource.

RE: PDF viewed in panel via ResourceReference works in 6.12 but not in 6.13

[Bruce Lombardi]

Martin,

I'm looking into mounting the resource but there is something that I don't 
understand. 
Currently I am creating the resource in my panel and passing the pdf I want to 
display into the constructor of the resource. If I mount the resource, how do I 
provide it with the dynamically generated pdf? I don't even see a way of 
getting a hold of the resourceReference object created and mounted in the  
WebApplication init() method. Perhaps I need to also register it as an 
application-shared resource, then access it in my panel constructor and add the 
pdf there?

Pass the info as parameters on the request to the mounted resource?

Passing something that allows you to produce the byte []?

RE: PDF viewed in panel via ResourceReference works in 6.12 but not in 6.13

[Bruce Lombardi]

That's not really possible. The pdf is produced by itext from a template with 
lots of parameter. It would require too large a change in the code and would 
couple the pdfViewer panel too closely to the domain code.

If, as Martin suggests, the automatic registering of the resource is not being 
done in the ResourceReferenceRegistry maybe there is something I could do to 
register and then unregister the resource similar to the way it must have been 
done in 6.12..

Re: PDF viewed in panel via ResourceReference works in 6.12 but not in 6.13

[Martin Grigorov]

Hi,

This is your code:

 WebDocsSession session = (WebDocsSession)getSession();
 final byte[] pdf = session.getPdf();
 if(pdf == null) System.out.println("PdfPanel session.getPdf returned
null");
 PdfResourceProducer pdfResourceProducer = new PdfResourceProducer(pdf);
 return pdfResourceProducer;


There is nothing Component specific here. Except #getSession(), but you can
use Session.get() and cast it. It is the same.

If you need the component to be able to generate the PDF bytes then you
need to implement IResourceListener interface. In #onResourceRequested()
you can generate the bytes and write them to the Response:
getResponse().write(byte[]).
The change you need to do is in #urlFor():
urlFor(ResourceListener.INTERFACE, parameters))

RE: PDF viewed in panel via ResourceReference works in 6.12 but not in 6.13

[Bruce Lombardi]

Thanks Martin an others. I am always impressed with the helpfulness of the 
people on this list.

I will look into what you suggest. In the meantime I'm trying to find out more 
information about the differences between versions and  I set the logger level 
to DEBUG and  obtained the traces below from working and non-working versions. 
Maybe this will help shed some light on what is happening. I see some 
differences like uri for working version starts with /wicket/resource but 
non-working version starts with /resource/ but I don't know what the 
differences mean.  Maybe someone know about this change?

If the difference in the way resource reference registration works between 6.12 
and 6.13  is an unintended  change in behavior between versions, it seems like 
it should be fixed. If it is an intended change, then it should be documented.

Hi,

This is your code:

 WebDocsSession session = (WebDocsSession)getSession();  final byte[] pdf = 
session.getPdf();  if(pdf == null) System.out.println("PdfPanel session.getPdf 
returned null");  PdfResourceProducer pdfResourceProducer = new 
PdfResourceProducer(pdf);  return pdfResourceProducer;


There is nothing Component specific here. Except #getSession(), but you can use 
Session.get() and cast it. It is the same.

If you need the component to be able to generate the PDF bytes then you need to 
implement IResourceListener interface. In #onResourceRequested() you can 
generate the bytes and write them to the Response:
getResponse().write(byte[]).
The change you need to do is in #urlFor():
urlFor(ResourceListener.INTERFACE, parameters))

RE: PDF viewed in panel via ResourceReference works in 6.12 but not in 6.13

[Bruce Lombardi]

The problem (which I think is a bug) is in the way the url is produced.

The line 
String url = (String)RequestCycle.get().urlFor(resourceReference, null);

Produces the url to use for the resource ref.

In the non-working version it returns:

../resource/org.apache.wicket.Application/pdfProducer

If I set a breakpoint just after this line and I manually remove the first dot 
in the string  using the debugger to get:

./resource/org.apache.wicket.Application/pdfProducer

and then let the code continue to run, my pdf appears correctly.

The debug trace also shows the correct uri.

2015-03-13 17:59:30,292  DEBUG - ServletWebRequest  - Calculating 
context relative path from: context path '', filterPrefix '', uri 
'/wicket/resource/org.apache.wicket.Application/pdfProducer'

2015-03-13 17:59:30,305  DEBUG - CompoundRequestMapper  - One compatible 
mapper found for URL 
'wicket/resource/org.apache.wicket.Application/pdfProducer' -> 'Mapper: 
org.apache.wicket.core.request.mapper.ResourceReferenceMapper; Score: 1'

Maybe someone knows how to fix this? I could strip the first dot as a 
workaround in the mean time.

Bruce

Bruce,

Apologies for my short answers of yesterday: texting from a mobile device
is not very confortable.  Would this class

https://github.com/reiern70/antilia-bits/blob/master/content-iframe/src/main/java/com/antilia/iframe/DocumentInlineFrame.java

be of some help for your use case?
