Detailed Description

This class holds patches for WebObjects dynamic elements, which have always a closing tag and all attribute values are enclosed in quotes. The patches are automatically registered if this framework gets loaded.
Note: WOForm is not replaced, because it is ok if you don't use ?-bindings. If you need additional parameters, just insert WOHiddenFields.
Also WOJavaScript is not replaced, even if it is not XHTML-conform.

Member Function Documentation

static final String addQuotes

(

String

atts

)

[static]

This method adds missing quotes to the given attribute string. E.g. type=text name="mytext" will be corrected to type="text" name="mytext"

Parameters:

atts

a string of attributes.

Returns:

the corrected string.

static void appendIdentifierTagAndValue	(	WODynamicElement	element,
		WOAssociation	id,
		WOResponse	response,
		WOContext	context
	)			[static]

Allows you to set the component ID without actually touching the HTML code, by adding a componentIdentifier entry in the context's mutableUserInfo. This is useful for setting CSS entries you don't have to code for.

static final int consumeAttributeName	(	String	string,
		int	index,
		StringBuffer	buf
	)			[static, private]

static final int consumeAttributeValue	(	String	string,
		int	index,
		StringBuffer	buf
	)			[static, private]

static final int consumeTag	(	String	string,
		int	index,
		StringBuffer	buf
	)			[static, private]

static final void correctResponse	(	WOResponse	response,
		int	start
	)			[static]

Corrects the response of dynamic elements to be XHTML-conformant. input- and img-tags will be closed correctly, all attribute values will be quoted and attributes without a value like disabled will get a quoted value. All attribute-values with uncorrectly escaped ampersands (&) will be corrected. E.g. "wählen" will become "wählen".
This method would normally be called in the following way:

 public void appendToResponse(WOResponse woresponse, WOContext wocontext) {
 	String pre = woresponse.contentString();
 	super.appendToResponse(woresponse, wocontext);
 	correctResponse(woresponse, pre.length(), pre);
 }
 

Parameters:

	response	the response to be corrected.
	start	the offset to start from.

static final StringBuffer getBuffer	(	String	src,
		int	len,
		StringBuffer	buf
	)			[static, private]

static final boolean isWhiteSpace

(

char

ch

)

[static, private]

Returns true if ch is an white space character, false otherwise.

Parameters:

ch

Returns:

true if ch is white space character, false otherwise.

static void processResponse	(	WODynamicElement	element,
		WOResponse	response,
		WOContext	context,
		int	priorOffset,
		String	name
	)			[static]

Fixing up the response for XHTML and adding the element to the array of generated element IDs, so we can use JavaScript later on. If the given element is an input element, it adds a dictionary {type=element.class, name=element.elementID} to ERXWOContext.contextDictionary().objectForKey("elementArray")
