Method Detail

lookupParam

public static String lookupParam(String lookup)

Determine if we have been passed a parameter ending in the param string, else null. We are doing an endsWith test, since the default JSF renderer embeds the parent identity in the HTML id string; we look for the id that was specified in the JSF.

Parameters:

lookup - JSF id String

Returns:

String the full parameter

paramLike

public static String paramLike(String paramPart)

Determine if we have been passed a parameter that contains a given string, else null. Typically this would be where you want to check for one of a set of similar commandLinks or commandButtons, such as the sortBy headings in evaluation.

Parameters:

paramPart - String to look for

Returns:

String last part of full parameter, corresponding to JSF id

paramArrayLike

public static ArrayList paramArrayLike(String paramPart)

Determine if we have been passed a parameter that contains a given string, return ArrayList of these Strings, else return empty list. Typically this would be where you want to check for one of a set of similar radio buttons commandLinks or commandButtons.

Parameters:

paramPart - String to look for

Returns:

ArrayList of last part Strings of full parameter, corresponding to JSF id

paramValueLike

public static String paramValueLike(String paramPart)

Determine if we have been passed a parameter that contains a given string, else null. Typically this would be where you want to check for one of a set of similar commandLinks or commandButtons, such as the sortBy headings in evaluation.

Parameters:

paramPart - String to look for

Returns:

String the value of the first hit

paramArrayValueLike

public static ArrayList paramArrayValueLike(String paramPart)

Determine if we have been passed a parameter that contains a given string, return ArrayList of the corresponding values, else return empty list. Typically this would be where you want to check for one of a set of similar radio buttons commandLinks or commandButtons.

Parameters:

paramPart - String to look for

Returns:

ArrayList of corresponding values

lookupBean

public static Serializable lookupBean(String beanName)

Helper method to look up backing bean. Don't forget to cast! e.g. (TemplateBean) ContextUtil.lookupBean("template")

Parameters:

context - the faces context

Returns:

the backing bean

Throws:

FacesException

lookupBeanFromExternalServlet

public static Serializable lookupBeanFromExternalServlet(String beanName,
                                                         javax.servlet.http.HttpServletRequest request,

Parameters:

beanName -

request - servlet request

response - servlet response

Returns:

the backing bean
