BeanUtils inside Struts can't deal with the two indexes back to back ("[i][k]").The reason why the original <logic:iterate> works, is because it cheats (yes, it cheats). Because it doesn't care about its children, all it does is get the collection using "childs[1]" and then makes a bean. It's this bean you're using in the write methods. Whereas, the nested tags simply organise the properties and then pass it to where it's being used, in this case the write tags, with property "groups.childs[1][0].name". But as I mentioned, bean utils can't handle it. To get it working, you'll need to wrap the second collection in a simple bean so you can get at it with another property like "groups.childs[1]another[0].name". Hopefully it wont be too much of a refactor, but beanUtils can't play with it as-is. All the best.
