OAF - Table Events

Table events are HTTP requests that are trapped and processed by OA Framework and handled during the processFormRequest phase.
EVENT_PARAM - indicates the event generated by a web bean (a table, in this case).

The possible events generated by a table are:

GOTO_EVENT - when 'Next' or 'Previous' navigation links are selected

SORT_EVENT - when a column header is selected to sort that column

HIDE_EVENT - when the 'Hide' link of a detail disclosure is selected

SHOW_EVENT - when the 'Show' link of a detail disclosure is selected

ADD_ROWS_EVENT - when the 'Add Another Row' button is selected

UPDATE_EVENT - when the total row 'Recalculate' button is selected

When the 'Next' or 'Previous' link of table navigation bar is selected, the value parameter contains the index of the first row of the current range. For example, when the row range 1-10 is displayed, the value is 1 and when the row range 11-20 is displayed, the value is
