The item selection dialog is used to select a variety of items in RAVEN. It is most often invoked by clicking on a Source Breadcrumb link (or the corresponding ... button).
The left side of the dialog displays the tree in which the required item exists. The right side of the dialog displays the contents of the currently selected collection. When a valid selection has been made, the OK button will become active. If the correct item type appears to be selected, but the OK button is greyed out, the selected item is an invalid selection, as it will cause a circualar data reference if used for the intended operation.
A source breadcrumb is a link describing the location of the currently selected item. Hovering the mouse cursor over the link (or the ... button) will provide a full-length location description. Clicking the link will allow selection of a new source using an Item Selection Dialog.
A checked listbox filter allows quick selection of items within a checked listbox using simple string matching. If a valid regular expression is detected in the filter box, it will be used to select items. Otherwise, all items with the entered string somewhere in their name will be selected (case-insensitive).
