Correct. The lazy manager has to be more intimately tied to the
layout because it needs to compute how many items will fit in order to
load just enough data. This is an area for improvement: there should
be a general protocol between replication and layout, but for now
there is not.

I seem to recall that the lazy replication manager assigns it's own
layout, ignoring any pre-existing one but you can assign an axis
and a spacing attribute.

Ok, adding a width and a height to the image solved the problem of

not being displayed, but there are still a couple of things that I
quite
don't understand, this works...
<view clip="true" width="540" height="90" id="contenido">
<view id="listado" layout="axis:x">
<image width="90" height="90">
<datapath xpath="s:/items[1]/item/imgurl/
text()" />
</image>
</view>
</view>
But, If I add replication="lazy" to the datapath definition things
no longer
works, two things happens:
* If I keep the image then I only see one (I believe I'm seeing
something
similar to the width and height issue).
* If I use a text then I see a list of the items but they don't
seem to
respect any layout option, the just appear one below the other.
Thank you!

I don't know what the warning is trying to indicate.
Is the data appearing? You may need to set the height explicitly, I
think there may be a bug in the replication manager updating
the view height automatically, so your images might be clipped.

I need to work with some large dataset, an XML having links to
images
that I
must show, basically a gallery like many around there, so I want
to do
some
paging and of course lazy replication, so, the basic code looks
like
this:
<view clip="true" width="540" id="cont">
<view id="list">
<simplelayout axis="x"/>
<image>
<datapath
xpath="s:/items[1]/item/img_url/text()"
replication="lazy"/>
</image>
</view>
</view>
But when I try this I get the following error:
INFO: __LZprocessOperator: p is null in Datapath for image
What am I missing?
Thank you!!
