In a JSFTemplating page:
<sun:table ... binding="bean.table" />
In your Bean.getTable() method:
public Table getTable() {
Table table = ...;
...
// Create the DynamicColumnRowGroup(s)
ComponentType type =
LayoutDefinitionManager.getGlobalComponentType("sun:dynamicColumnRowGroup");
for (Object yourData : listOfYourData) {
LayoutComponent desc = new LayoutComponent(null,
yourData.getId(), type);
for (.... : listOfProperties) {
// Add each property that would normally appear in the .jsf
file, i.e:
// <sun:dynamicColumnRowGroup ... property1="value1"
property2="value2"...
desc.addOption(key, value);
}
// Create and add child component (dynamicColumnRowGroup)
UIComponent rowGroup = ComponentUtil.createChildComponent(
facesContext, desc, table);
}
// Return the populated table
return table;
}
However, now that I went through the motions of giving you the above
pseudo-code, I realize why I don't like "binding". :) The above will
work, however, you can't parameterize a binding. If you want to pass in
a reference to "yourData" it's not possible. So instead, if you want,
you can create a custom JSFT Factory (just like
DynamicColumnTableRowGroupFactory). This could do essentially the exact
same code, you can just take advantage of the properties passed in, and
also context.getLayoutElement() which is what should have been passed
into the "null" argument in new LayoutComponent() (but it's not
available via a binding... not very important, though).
A 3rd option, would be to write this code in a handler and invoke it on
the afterCreate event.
So many choices. :) I hope this helps!
