Subject RE: Outputting raw HTML with s:property tag
Date Thu, 03 Jan 2008 07:44:01 GMT
A polymorphic array would be my suggestion.

Have an array of objects which contain an identifier for the struts tag
type, and the data needed to populate it. For example;

In your action you would have ;


private MyPolyObject[] blah;


Where MyPolyObject contains;


class MyPolyObject {
	private int type
	private String value
...
}

Then your JSP has

<s:iterator value="blah">
	<s:if test="type==1">
		<s:property value="%{value}">
	</s:if>
	<s:elseif test="type==2">
		<s:textfield value="%{value}">
	</s:elseif>
	....
</s:iterator>

You can then build extend MyPolyObject into classes which hold the
information for specific types (e.g. a Map for the s:select type).

Hope this helps.

Al.

Subject: Re: Outputting raw HTML with s:property tag


OK, here's what I'm doing: I am generating forms from external data.
Meaning, I have some XML files, based on which, I am generating a form.

Normally I could do this without Actions, but rather include a bean into a
JSP file (am I right about that?)

However, I also need to use request and response information, and that is
why I was trying to do this through an action. 

Perhaps you have some suggestions for me?

Thanks.
