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 */
