> Introduction
> Apache Tapestry supplies powerful component structure, and it offered a
> number of other powerful features that proved to be critical in our work.
> The Eclipse Web Tools Platform (WTP) project extends the Eclipse platform
> with tools for developing Web and Java EE applications. It includes source
> and graphical editors for a variety of languages, wizards and built-in
> applications to simplify development, and tools and APIs to support
> deploying, running, and testing apps.WTP supplies Web Page Editor for us to
> edit HTML page, JSP page and JSF-JSP web page.
> Tapestry was used widely nowadays, it allowed a clean separation between Java
> and HTML, and made it possible for the design work on the application to
> continue well after the code had been completed, It is becoming more and more
> popular today. But we can not find a proper Tapestry visual editor, Eclipse
> WTP is popular in Web application development, but it is a shame that Eclipse
> WTP does not support Tapestry, so i think it is a good idea to build a
> Tapestry visual editor on Eclipse WTP.
> This editor should have following mainly functions:
> Note GSoC supplies us only 3 months to finish our project, so this project
> will focus on Tapestry 5, after that, if we have enough time, will supply
> other Tapestry version support
> Must have functions
> 1. Tapertry libraries import wizard
> Add necessary Tapestry 5 relative jars into web project.
> 2. Tapestry page/component creation wizard
> It will supply a wizard helping us to create the .tml file and .java file
> together for a Tapestry page/component.
> 3. Add Tapestry component support for WTP web editor palette
> If we open a Tapestry page/component with WTP Web Page Editor, its palette
> will contains three main section, HTML,Tapestry core and Tapestry custom
> component. Then, we can drap-and-drop the components in the palette to the
> canvas. WTP web editor supplies property view for us already, we can improve
> the property to support Tapestry component. In Tapestry Core section, it
> includes Tapestry standard components, Foreach, Insert,Image,Conditional,
> Form components and the other standard components.
> NOTE Eclipse WTP supplies relative interface for us to change palette
> components
> 4. Add convenient way for the Web Page Editor to change-over between a
> Tapestry page's .tml file and .java file
> 5. Add Tapestry built in and custom components autocomplete function for WTP
> Web Page Editor's source view
> If we add component insert code, such as
> <span jwcid="@Insert"/>
> ,So when you type
> <span jwcid="@
> it comes up with a list you can choose from and then completes it with the
> required parameters listed.
> 6.Tapestry component's parameters property view
> We select a component in canvas design view or source view, the Eclipse
> property view will list this component's parameters and we can edit the
> parameters here.
> 7.Autocomplete of properties from the .java page when editing the .tml file
> In the Source Page of the Web Page Editor, add the Tapestry tag, (for example
> ${prop:index}). With the cursor inside the brackets, hit Ctrl+spacebar,
> should see a pop-up with a list of all the available properties defined in
> the corresponding java class.
> Optional features
> 8. Validation function in Tapestry .tml file source view
> Beyond the basic JSP validation already provided with the JSP editor, this
> editor supplies semantic validation of the Tapestry standard tag libraries
> for both EL and non-EL attribute values.
> 9. Hyperlink function in Tapestry .tml file source view
> Hyperlink to the Java editor from Managed Bean variable, Managed Bean
> property and Managed Bean method referenced in the Expression Language(EL) of
> a tag-attribute.
> I have finished some research job and familiar with Eclipse WTP source code,
> so i think it is definitely for us to finish function 1-7 during this summer.
> Function 8 and 9 are more complex and not so necessary, so i mark them as
> optional features. Once i finished must-have functions development job, i
> will start option features job.
> Online design demo
> You can go here[1] to see project proposal details with picture demos.
