SpringXT : JSP based component ?

[ndeloof]

Hello,

I'm just starting looking at SpringXT. From documentation samples it seems I have to build the HTML replacement code using Components that map my HTML structure. Is there any way to use a JSP to build this HTML ?

In some case it may be simplier to write a JSP file to produce (x)HTML than building a DOM model based on java classes. If I want to build a tableBody content, It is easy in JSP to use a <c:foreach> inside a table canvas, but this requires lot's of code to add TableRow / TableDatas and then my formated content.

Is there any support for this, or plan for such a use case ?

Another use case I'd like to use is to return Javascript code. I'm using openRico Effects to create a nice transition between my two phase transaction (some blocks fade, some other reduces, and a confirm box appears). I'd like this JavaScript code to be in a separate JS file. Can I use SpringXT to replace some fake DIV content with my JS content and eval it ? (I can do this using Prototype Ajax.Updater).

A third use case is a combination of those two : my JSP code could be created from a JSP, so that some content can be dynamically created.

Can I expect such features in springXT ?

Hi,

thanks for your interest in XT Ajax Framework.

> Is there any way to use a JSP to build this HTML ?

There's a Jira issue about that:
http://opensource.atlassian.com/projects/spring/browse/MOD-212
It is planned for the next release.

I'm working for building a complete effects solution based on Prototype/Scriptaculous.
However, you are able to use your preferred Ajax suite: just use the ExecuteJavascriptFunctionAction action (https://springmodules.dev.java.net/source/browse/*checkout*/springmodules/www/docs/javadocs/0.6/org/springmodules/xt/ajax/action/ExecuteJavascriptFunctionAction.html ).
It will let you call a JS function placed in a client side script (take a look at its javadoc).
If you need something different, you can always create a Jira issue ;)

It is not clear what you mean: can you explain better?

If I understand the Javadoc, ExecuteJavascriptFunctionAction is designed to execute a JS function that is allready define in the browser HTML. I'd like to include the function definition/body in the Ajax response, so that I can create a separated JS file for any "transition", without having a huge myApp.js with all possible effects that my page includes.

If I want to build an Ajax application "in a single HTML page", I'll need lot's of such transition and I don't want my page to include a huge "mayApp.js" with code for all possible effects.

I also would like the JS function code to be created on the fly from a JSP, so that some parts can be dynamically generated, according to user state or any contextual data.

Yes, you are right.

So, if I understand, you want to include in the Ajax response a function definition read *by server side* from a JS file, and then execute it *by client side* ... am I right?

I understand.

Such a features are not planned at the moment.
If you are interested, can you create two different Jira issues?
Once created, I'll evaluate if include them for the next release.

Thanks,
