Figure 7-9. Block of state morphed to a new representation One of the advantages of Dynamic HTML is that state can be embedded within a representation, thus making it unnecessary to store the state in a variable executing in the context of a JavaScript script. To assign or retrieve the state, the property document.getElementById ( "div").innerHTML is used. This is one of the advantages of the Representation Morphing pattern: the state does not have to be converted from the memory of an executing script into a representation and back again. The only requirement is that the state needs to be stored in such a way that a script can easily extract the information. Some readers may realize that the Representation Morphing pattern is similar to XForms.5 Although the Representation Morphing pattern could be used like an XForm, the main thrust of this pattern is to create a state that is embedded in a representation. The state could repreE B V N sent a form, but it doesn t have to. The state could be an HTML document that is manipulated over time, such as a word processing document. The Representation Morphing pattern comes into play when the state in Figure 7-9 is converted into an HTML form for user editing purposes. Then as the state has been edited, the representation changes back to Figure 7-9 with the new values. This transformation is a morphing of representation using a common state and is illustrated in Figure 7-10. Figure 7-10 shows two states with two representations. The arrows indicate the direction of morphing. The transformation blocks are functionality used to morph the state from one representation to another representation. It is important to have bidirectional morphing capabilities, because only with bidirectional morphing can you be assured that no state is lost or corrupted. This bidirectional capability goes back to the argument of adding two numbers and getting a result. Consistent bidirectional behavior would require that the two numbers that are added and the addition result constitute a result.

TiddlyWiki may not completely implement the Representation Morphing pattern, but the concept is there. There is an editable representation that edits the state, and a viewable representation that views the state. Each representation is a best-of-breed representation useful for the context of viewing or editing the state. Between the two representations the state is identical, and converting from one representation to another does not add or remove data from the state.

The implementation of the Representation Morphing pattern focuses on defining the state (as in Figure 7-8) and morphing the state (as in Figure 7-9). In this section, the first example implementation will focus on a purely JavaScript solution, and the second example will be a simplified implementation illustrating how XSLT could be used to morph content from one representation to another. Regardless of which solution is used, a complete Representation Morphing implementation requires some special techniques to get around the problems of Dynamic HTML.
Implementing the Framework
The aim of this example implementation is to fully implement the Representation Morphing pattern for the state of Block 1 in Figure 7-9. The example will convert the editable representation of the HTML form into a viewable representation, and then to another editable representation. The second editable representation morphing is the result of using XSLT. In total, there are three representations, but only one state. All of the representations displayed E B V N side by side without any state is identical to Figure 7-12. It goes without saying that in your HTML pages, the transition from one representation to another will be visually pleasing, as in Figure 7-11.
Figure 7-12. Example HTML page without any state Figure 7-12 shows three representations with no state. The first representation is the Personal Information grouping, the second is the table labeled Years, and the third is the unseen div element between the second representation and the Reset Form button. If all of the representations are filled in with information, the HTML page will resemble Figure 7-13.
