Move the defaulting of the focusRowKey attribute for the TreeTable component to
the renderer
--------------------------------------------------------------------------------------------
Key: ADFFACES-288
URL: http://issues.apache.org/jira/browse/ADFFACES-288
Project: MyFaces ADF-Faces
Issue Type: Improvement
Environment: All
Reporter: Kamran Kashanian
The Trinidad TreeTable is limited to a single root node. The root node that is
displayed by the TreeTable is indicated by the focusRowKey attribute of
TreeTable. When no focusRowKey attribute is specified, TreeTable defaults the
focusRowKey to the first node in the tree model. This defaulting of the
focusRowKey attribute is done in a package scoped method (__init()) of the
UIXTreeTable class. Since there is no hook for subclasses of UIXTreeTable to
override the defaulting of the focusRowKey attribute, the subclasses are also
limited to a single root node (if they use the same focusRowKey logic to
display the root node.)
The proposal is to move the defaulting of the focusRowKey attribute out of the
UIXTreeTable component and into the renderer. This allows subclasses of
UIXTreeTable to handle a null focusRowKey and display multiple root nodes.
This patch includes this change. Also currently both Tree and TreeTable
initially expand the focusRowKey node. This initial expansion was also being
done in the component. This patch moves the initial expansion of the
focusRowKey node into the renderer.
