Creating a Custom Guest Class

11. Click in the component window, then press Tab.

Pressing Tab when editing a table causes the contents of the next cell

to the right to be selected (or the ﬁrst cell of the next row if in the

rightmost column). Pressing Shift-Tab moves in the opposite direction

through the table.

12. Repeat steps 7 through 11 for the second and third cells of the top row.

Label the middle column

E-mail and set its width to 150 pixels. Label

the third column

Comments and leave its width unset. (The comments

ﬁeld takes up the remainder of the width of the table.)

Note: It isn’t necessary to adjust the height of the columns, since they

expand at run time to accommodate the size of the text being

displayed.

Adding Dynamic Elements to Table Cells

Tables and cells are static HTML elements, so you can’t bind them to

variables or methods. To display dynamic information in cells, you add

dynamic elements, such as WOStrings, to the cells.

1. Select the contents of the ﬁrst cell in the second row of the table by

clicking in the cell, then double-clicking the text.

2. Choose from the Elements pop-up list.

3. Click to add a WOString to the cell.

4. Press the Tab key.

The contents of the next cell to the right are selected.

5. Repeat steps 3 and 4 for the other two cells in the second row.

Binding the Dynamic Elements in the Table

1. Select currentGuest.guestName in the object browser and drag the cursor to

the center of the WOString in the ﬁrst column to bind its

value attribute.

2. Similarly, bind

currentGuest.email and currentGuest.comments to the second and

third WOStrings.
