Building Dynamic WAP Applications with ColdFusion

Studio/HomeSite Features for Creating WAP Apps

As mentioned before, CF Studio is the IDE for ColdFusion coding. On the surface, Studio is a text editor, albeit one with many valuable features for web page developers. It's based on Allaire's award-winning HomeSite HTML editor. Studio simply adds many features specifically for ColdFusion developers. Both Studio and HomeSite, like ColdFusion, can just as easily be used to create WML pages if you know what to write. However, release 4.5 offers features that are specifically geared toward WML developers to help make coding easier, especially if you're new to WML. (From now on, I'll refer to simply Studio but all these features are in both Studio and HomeSite.)

New Page Wizard

To make Studio create a new, skeletal page for coding WML applications with CF, use the File | New menu command and choose the WML tab from the dialogue offered. From there, you have the choice of creating a new, blank template with skeletal WML code and either with or without the <CFCONTENT> tag filled in for you (referred to as dynamic or static, respectively):

 


Tag Insight

Even more valuable, when entering tags in Studio (whether HTML or WML), is a feature called Tag Insight. If, after entering the tag name and a space, you wait a second, you'll be presented with a list of all the valid attributes for the given tag:

 

Tag Editors

Another useful feature for editing WML code is Studio's Tag Editor. With this, you can place the cursor on a tag and either right-click and choose Edit Tag, or press Ctrl-F4, which pops up a dialog that displays the available attributes and their appropriate values (where they are predefined). Also, this feature often presents the attributes in the order of their most likely usefulness, whereas Tag Insight simply presents them in alphabetical order:

 


Tag Help

Yet another useful feature is Studio's built-in help. Sometimes, you may not want to see the available attributes in a dialog (like the Tag Editor) or in a list (as in the Tag Insight feature). You may just want to read about the available attributes and their predefined values (if any). To do that, simply press the F1 key while the cursor is on an element (CF, HTML, or WML). Studio will open a help window for that element:

 

 

To return to editing your code, simply press F12 or click the Edit button offered above the window showing the help.

 

Studio's tag editing features are powerful; they make it easy to enter code while typing (Tag Insight) and provide assistance when you're not sure how to proceed (Tag Insight, Tag Editor, and Tag Help).
