Re: Outputting raw HTML with s:property tag
Leaving aside the issue that you really shouldn't be spitting HTML out
of calls to action methods, the answer to your question is no. JSPs are
aren't processed 'recursively' like that; you can't have the result of
evaluating something in a JSP be something that needs evaluating.
Why do you want this? It sounds like you're trying to do too much of
your presentation logic in action code, which is generally a bad idea.
If you describe what you're trying to achieve, someone can probably
suggest a better approach.

Thanks, I think that'll do it!

RE: Outputting raw HTML with s:property tag
Posted by Al Sutton <al...@alsutton.com>.
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.

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.

Re: Outputting raw HTML with s:property tag
Posted by shai200 <sh...@gmail.com>.
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.
