Page number instead of number of entries

[Former Member]

Hello

I have a requirement for changing the number of entries in KM to page numbers.

So I need to change:

1-10 11-20 21-24

to

1 2 3

I found a thread on sdn about this requirement, but there wasn't much information. It just said to write your own Collection Renderer.

I was able to add something between the breadcrumb (showing the map you are on the moment) and page numbers. So I still don't know where the 'page numbers' are added?

Is there anyone with experience? Or ideas?

Thanks!

Hi,

The codes that render the PagerComponent are in renderDecorations method of LightCollectionRenderer.

So override this method and implement your own pager.

Implementation is not so straight forward, so look into the codes and let me know if you need more help.

Also check this:

Hello

This was my first thought where it had to be done. So I already have the decompiled files. But I can't seem to find where it is exactly done in this CollectionRendererDecorator, the constructor which is called in the renderDecorations method of LightCollectionRenderer.

	protected Component renderDecorations(Component comp)
		throws WcmException
	{
		return new CollectionRendererDecorator(comp, this, getProxy(), getComponentValueMap(), getParentCollection());
	}

I'll have a try, but any help would be really nice and I would be really gratefull!

Hello

Ok, I got the pagerData. Here, you find the number of items, the items per page, the startrow, number of links (don't know what this is) and a boolean for the 'more' modus, the others are all integers.

But now, I'm wondering how to make links to show the following page with items. Any idea?

Christof

[Former Member]

The StartRow is used to tell the rendere where to start.

So you got a list of 23 items and 15 items at each page gives the following:

15 items

1-15 15-23

and startrow = 0

8 items

1-15 15-23

and startrow = 15

Am I going in the rigth direction, by trying to set this startrow? Or do I need to fire events or?

Somebody got an idea about where setting it?

Hello

I still seem to have a problem. I think I got to change stuff in the renderIntervalLinks method of 'KenGPager'. But it doesn't matter what I change, he always shows the standard numbers..

This is what I did.

I created a methode renderDecorations in the class CollectionListRenderer. (I'm sure he uses this method, because if I add more components, they are shown )

	protected Component renderDecorations(Component comp)
	{
		int col = 1;
		int row = 1;
		GridLayout grid = new GridLayout();
		Container container = grid;

		try
		{
			grid.addComponent(row, col, new KenGCollectionRendererDecorator(comp, this, getProxy(), getComponentValueMap(), getParentCollection()));
		}
		catch (WcmException e2)
		{
			// TODO Auto-generated catch block
			e2.printStackTrace();
		}
		return container;
	}

As you see, I use the class KenGCollectionRendererDecorator.

I created the class and changed the method to use my pager, using the alias:

	private Component renderPager()
		throws WcmException
	{
		IComponent comp = ComponentFactory.getInstance().getComponent("KenGPager", proxy, renderer, resource, null);
		if(comp == null)
		{
			return EmptyHtmlFragment.render();
		} else
		{
			comp.setData(valueMap);
			return comp.render();
		}
	}

The pager references to KenGPager.

Mapping -> Component: 
KenGPager be.kindengezin.wcm.rendering.component.cm.KenGPager 

Do you see anything wrong?

Christof

[praveenkumar_gudapati]

Hi,

Did you restart the server after deploying your application?

Also add some logging into code so that you can debug what is going wrong.

Add logging in renderDecorations method as well as in KenGCollectionRendererDecorator class as well as other custom classes.

If the debug mode is enabled on your server then you can also debug using break points in codes using NWDS.

Hi,

Check that the SharingReferences are properly set.

If CrtClassLoader does not find your classes then it is most probably due to SharingReferences problems.

Regards,

Praveen Gudapati

[Former Member]

Hello

Thanks for the response.

I got 3 libs I don't know what to do with. Htmlb.jar, servlet.jar and logging.jar. I used servlet.jar in mij collection renderer and this one works as long as I don't call the KenGPager (there is an error on this pager: ClassNotFoundException). Htmlb is used through htmlb. But the other 2 I don't know how to handle them.

The servlet.jar isn't mentioned in my portalapp.xml of the CollectionListRenderer.

I added one missing reference in the SharingRefences, but I still get the same error. Other ideas?

Christof

[praveenkumar_gudapati]

Hi,

Did you restart server after adding missing SharingReference?

Hello

Not yet, because some others are working on the server for the moment...

But crt Classloader is loading everything after you add mapping. (I noticed this in nwa -> logs).

Hello

I restarted the server (it's today finally whole mine) and saw the collection renderer and Pager both get the java.lang.ClassNotFoundException exception. But still can't figure out why they can't be found, because they exist.
