Select
public class Select extends ListUIBean (Code)
Render an HTML input tag of type select.

Examples

 
 <ww:select label="Pets"
 name="petIds"
 list="petDao.pets"
 listKey="id"
 listValue="name"
 multiple="true"
 size="3"
 required="true"
 />
 <ww:select label="Months"
 name="months"
 headerKey="-1" headerValue="Select Month"
 list="#{'01':'Jan', '02':'Feb', [...]}"
 value="selectedMonth"
 required="true"
 />
 // The month id (01, 02, ...) returned by the getSelectedMonth() call
 // against the stack will be auto-selected
 
 

Note: For any of the tags that use lists (select probably being the most ubiquitous), which uses the OGNL list notation (see the "months" example above), it should be noted that the map key created (in the months example, the '01', '02', etc.) is typed. '1' is a char, '01' is a String, "1" is a String. This is important since if the value returned by your "value" attribute is NOT the same type as the key in the "list" attribute, they WILL NOT MATCH, even though their String values may be equivalent. If they don't match, nothing in your list will be auto-selected.

Field Detail
TEMPLATE
final public static String TEMPLATE(Code)



emptyOption
protected String emptyOption(Code)



headerKey
protected String headerKey(Code)



headerValue
protected String headerValue(Code)



multiple
protected String multiple(Code)



size
protected String size(Code)




Constructor Detail
Select
public Select(OgnlValueStack stack, HttpServletRequest request, HttpServletResponse response)(Code)




Method Detail
evaluateExtraParams
public void evaluateExtraParams()(Code)



getDefaultTemplate
protected String getDefaultTemplate()(Code)



setEmptyOption
public void setEmptyOption(String emptyOption)(Code)
Whether or not to add an empty (--) option after the header option



setHeaderKey
public void setHeaderKey(String headerKey)(Code)
Key for first item in list. Must not be empty! "'-1'" and "''" is correct, "" is bad.



setHeaderValue
public void setHeaderValue(String headerValue)(Code)
Value expression for first item in list



setMultiple
public void setMultiple(String multiple)(Code)
Creates a multiple select. The tag will pre-select multiple values if the values are passed as an Array (of appropriate types) via the value attribute. Passing a Collection may work too? Haven't tested this.



setSize
public void setSize(String size)(Code)
Size of the element box (# of elements to show)
