hi am having this error where regenarating JHeadstart Application Generator,am using jdeveloper 11g release 2 JHeadstart 11.1.2
Flag that indicates how the content of the region container must be displayed.
When the layoutStyle is set to 'Modal Popup Window' or 'Modeless Popup Window' a button is generated to launch the popup if the
'Depends on Item' property is not set. If the 'Depends on Item' property is set, the item context facet is used to launch the popup.
(default value = vertical)
JAG-00159 [ Countries / Locations2 ] Group Usage property must be set to 'Region with Page Fragments' and Group Region Access property must be set to 'Group UI Shell Page' for trees that contain tree-form layout. When using reusableTree layout, these restrictions do not apply.
[ Countries / Locations2 ] A base tree group that is not reusable cannot be a child group. See the JHeadstart Developer's guide for instructions on how to get a tree with a limited set of root nodes.
JAG-00080 [ Countries / Locations2 ] Group property 'Tree Data Collection' is required with Layout Style 'tree'.
JAG-00080 [ Regions / Countries2 / Locations3 ] Group property 'Tree Data Collection' is required with Layout Style 'tree-form'.
JAG-00080 [ Regions / Countries2 / Locations3 / Departments4 ] Group property 'Tree Data Collection' is required with Layout Style 'tree-form'.
The error messages you're getting from the generator seem fairly self explanatory. Is there a specific one you're having trouble resolving, or is there something more specific that is not behaving as you expect it to?
You should read through section 5.7 of the JHeadstart Developer's Guide and section 4.5 of the End-to-End Tutorial. Both are available on the main JHeadstart page at http://www.oracle.com/technetwork/developer-tools/jheadstart/overview/index.html .
