doLoad
public void doLoad(Widget frmModel,
org.apache.commons.jxpath.JXPathContext jxpc)
throws BindingException
- Binds the unique-id of the repeated rows, and narrows the context on
objectModelContext and Repeater to the repeated rows before handing
over to the actual binding-children.
- Specified by:
doLoad
in class JXPathBindingBase
- Throws:
BindingException
doSave
public void doSave(Widget frmModel,
org.apache.commons.jxpath.JXPathContext jxpc)
throws BindingException
- Uses the mapped identity of each row to detect if rows have been
updated, inserted or removed. Depending on what happened the appropriate
child-bindings are allowed to visit the narrowed contexts.
- Specified by:
doSave
in class JXPathBindingBase
- Throws:
BindingException
