Even though the biography will be brief, a text box is not convenient for
entering a long string. There is a much more convenient control for this purpose in
HTML,

. In Tapestry, such control can be displayed by the TextArea component. Here is what we should do to override the default choice for editing the biography property of the displayed object: <t:beaneditform t:id="celebrity" t:submitLabel="Save" remove="id" reorder="firstName,lastName,dateOfBirth,birthDateVerified, occupation,biography"> <t:parameter name="biography"> <t:label for="biography"/> <t:textarea t:id="biography" t:value="celebrity.biography"/> </t:parameter> </t:beaneditform> In a way similar to what we did with the Grid component to override the default rendering of a certain column, we are using a <t:parameter> element. Here it repeats the name of the property for which we want to provide an alternative editor. Inside this element we are using a TextArea component, in the same way as we used TextField in the previous chapter. If you run the application now, the form should look like this: Advanced Components [ 144 ] This is already better. If you think that you'd prefer to have more space for a biography, try this: <t:textarea t:id="biography" t:value="celebrity.
