Re: textarea and wrap
The Struts Action works through introspection. It doesn't know (or care) whether the value in a form was rendered by a Struts custom tag or not. This means if you use a standard textarea tag in your form, and give it a name that matches a property in your form bean, Struts will use that attribute just as if it had been rendered by a html:textarea tag. After all, this is all the Struts html:textarea tag does. To seed the textarea from the form bean, you could code something like And everything else will be automagical again. What I would like to propose and contribute in the 1.1 timeframe is the addition of a "options" attribute to all the HTML tags, so we could code something like and have Struts add wrap="soft" to the tag without interpretation. This would make all the tags extensible for non-standard properties. William Jaynes wrote: > > I usually need 'wrap="virtual"' as an attribute for my textareas.

RE: textarea and wrap
I have had other similar issues and I think a very useful enhancement to all
Struts tags would be to make them more granular so that they could be easily
sub-classed and modified. Currently methods such as doStartTag() tend to
have one big lump of code which means if you want to change it behaviour you
have to override it and then duplicate much of the code in the original
method. An example of the kind of structure I'm looking for is below:
>From the CheckboxTag:
public int doStartTag() throws JspException {
StringBuffer results = new StringBuffer("");
// Print this field to our output writer
JspWriter writer = pageContext.getOut();
try {
writer.print(results.toString());
} catch (IOException e) {
throw new JspException
(messages.getMessage("common.io", e.toString()));
}
// Continue processing this page
return (EVAL_BODY_TAG);
}
protected String prepareName() {
return " name=\""+this.property+"\"";
}
etc. etc.

Re: textarea and wrap
I posted a bug report and sent a patch for struts on this one. I think this was last week. The committers decided not to include it, because the wrap attribute is not in the HTML spec. This is really unfortunate, escpecially because the little patch I already provided is just a minor change and would be useful for pretty many developers, I think. So what I am doing: I am patching struts locally. You should be able to find my mail with the patch in the mail-archive. --- Matthias William Jaynes wrote: > > I usually need 'wrap="virtual"' as an attribute for my textareas.
