JSF Components in Tables
Deleting Rows
- To this point, we have used only output components in table columns, but you can place any JSF component in a table cell.
- We use the current integer to configure components in the “Number”, “Textfields”, “Buttons”, and “Menu” columns.
- Components in a table are no different than components outside a table;
- You can manipulate them in any manner you desire, including conditional rendering with the rendered attribute, handling events, and the like.
- Editing Table Cells
- To edit table cells, you provide an input component for the cell you want to edit.
- You click a checkbox to edit a row and then click the “Save Changes” button to save your changes.
- Exa.
Deleting Rows
- When deleting or adding rows, it would be tedious to use an array to collect the row data.
- Use a list instead.
- We will simply use an ArrayList
in our example. - Exa.
- Databases store information in tables, so the JSF data table component is a good fit for showing data stored in a database.
- In this section, we show you how to display the results of a database query.
- When you use a Java object, array, list, result set, or JSTL result object to represent table data, h:dataTable wraps those objects in a model that extends the javax.faces.model.DataModel class.
- All of those model classes, listed below, reside in the javax.faces.model package.
- ArrayDataModel
- ListDataModel
- ResultDataModel
- ResultSetDataModel
- ScalarDataModel
