Richard,
* you would probably want to check in flow if the binding worked before asking to showForm() the thing form.lookupWidget("path-expression").getValue() might be helpful
* by default logging level on the various aspects of cocoon has a quite high treshold, you'ld need to change logkit.xconf (in build/webapp/WEB-INF) to read e.g.
<category log-level="DEBUG" name="forms">
<log-target id-ref="forms"/>
<log-target id-ref="error"/>
</category>after witch you can check the file forms.log (in build/webapp/WEB-INF/logs)
you'll get quite a big list of statements out of this, happy reading ;-)
* alternatively you could also remotely connect to the jetty-vm and step-debug (e.g with eclipse)
* snippets of what we did: (although I think this is less useful)

Richard,
I have some nested repeaters working (definition and binding to beans) in a smaller app. What exactly is not working for you?
(I must admit I haven't tried nesting the widget-labels nor the actions, both could be subject to some required patching, details of what goes wrong (stacktraces?) or contrary to your expectations might be useful)

Hi,
i'm quite new to Cocoon and CForms.
I'm checking out Forms-related-technologies and having a question on CForms about editing "deep" structures (lists containing lists, etc) now - i'm using 2.2-dev (i've first checked 2.1.51 and then switched to dev), Win2k, JRE 1.4.2_02.
In my first test i'm trying to edit the following xml-structure using CForms:
the "/units/unit"-level forms level one for editing
the "/unit/conversions/conversion" is the level which is supposed to nest in Level1
my approach is to nest repeaters (which doesn't seem to be supported, but maybe i'm missing something) - any suggestions welcome.
the accompanying data, sitemap, template, model, binding - in that order (all being based on the forms2-xml-binding-example):
/* units_data.xml */ <units> <unit> <name>Length</name> <itemid>1</itemid> <baseconvid>1_1</baseconvid> <conversions> <conversion> <convid>1_1</convid> <si> <shortterm>m</shortterm> <factor>1</factor> </si> <imp> <shortterm>ft</shortterm> <factor>3,280839895013123</factor> </imp> </conversion> <conversion> <convid>1_2</convid> <si> <shortterm>cm</shortterm> <factor>100</factor> </si> <imp> <shortterm>in</shortterm> <factor>39,37007874015748</factor> </imp> </conversion> <conversion> <convid>1_3</convid> <si> <shortterm>mm</shortterm> <factor>1000</factor> </si> <imp> <shortterm>in</shortterm> <factor>39,37007874015748</factor> </imp> </conversion> </conversions> </unit> <unit> <name>Area</name> <itemid>2</itemid> <baseconvid>2_1</baseconvid> <conversions> <conversion> <convid>2_1</convid> <si> <shortterm>m<sup>2</sup></shortterm> <factor>1</factor> </si> <imp> <shortterm>ft<sup>2</sup></shortterm> <factor>10,763910416709722</factor> </imp> </conversion> <conversion> <convid>2_2</convid> <si> <shortterm>cm<sup>2</sup></shortterm> <factor>10000</factor> </si> <imp> <shortterm>in<sup>2</sup></shortterm> <factor>1550,0031000062001</factor> </imp> </conversion> </conversions> </unit> </units>

Hello Marc,
thanks for answering - i've attached a screenshot of what is rendered with the given configuration.
the result should be:
data in the nested Table/Repeater (only headers are shown), and action-buttons
I'm using xml-binding and didn't want to use bean-binding (since i would like to avoid beans for now). I don't see error-messages - to me it looks like it's unsupported.
could you give me snippets of your working configuration?
thanks, Richard
