"to-content" chunk not working

Hi All,

I am using FM11 and RH10 from the ATCS4 tech suite.

Am not sure if its DITA in FM or Robohelp, but one of them is not listening to the chunking attribute that i have keyed in.

For example, i have the following tree structure in my dita map:

ConceptParent (given the chunking attribute at this level in the ditamap; chunk = "to-content")

Concept

Topic

Task

I am generating help directly using Publish option from Framemaker. I wanted all the topics to appear under the Parent Concept when i generate the html files, but its not happening. This is quite critical as we are creating articles and want to group topics/tasks under the same parent rather than spiltting it into different HTML pages.

Please help.

Regards

Sharada
