Thanks. This works, but it also prints out duplicate "class" attributes.
class="text large error" class="text large"
It'd be nice to have something like:
writer.appendAttribute("class", "values to append");
Another question - it seems my full <label> and <input> is getting
wrapped with
<font color="red">
Is there anyway to get rid of that? It's problematic b/c the closing
</font> isn't getting rendered until right before </form>.
Fixed this by using:
public void writeLabelPrefix(IFormComponent component,
IMarkupWriter writer, IRequestCycle
cycle) {
// does nothing put prevent <font color="red"> from getting written
}
Thanks,
Matt

Hmmm, I'm guessing the answers to my questions below are "no, this
isn't possible." ;-)
Here's another question - is it possible in my custom Validator to
get the existing CSS classes on a component? For example, I
currently have:
public void writeLabelAttributes(IMarkupWriter writer,
IRequestCycle cycle, IFormComponent component) {
if (isInError(component)) {
writer.attribute("class", "error");
}
}
public void writeAttributes(IMarkupWriter writer, IRequestCycle
cycle,
IFormComponent component, IValidator
validator) {
if (isInError()) {
writer.attribute("class", "error");
}
}
But I'd prefer to have something like this:
public void writeLabelAttributes(IMarkupWriter writer,
IRequestCycle cycle, IFormComponent component) {
if (isInError(component)) {
writer.attribute("class", "error " +
component.getAttribute("class"));
}
}
public void writeAttributes(IMarkupWriter writer, IRequestCycle
cycle,
IFormComponent component, IValidator
validator) {
if (isInError()) {
writer.attribute("class", "error " +
component.getAttribute("class"));
}
}
In other words, is there a method on component that allows me to get
the current CSS classes?

I have two different "Label" components I'm trying to create.
Issue #1
---------------------------
The first is a simple component (just a Label.jwc and Label.html
file in WEB-INF) that writes a <label>. I'd like to include the
option to write a "required" indicator. However, I'm having a
difficult time retrieving a parameter's value. Here's what I have
so far:
Label.jwc
<component-specification allow-informal-parameters="yes">
<parameter name="key" required="yes"/>
<parameter name="class" required="no"/>
<component id="label" type="Any"
inherit-informal-parameters="yes"/>
</component-specification>
Label.html
<label jwcid="label"><span jwcid="@Insert"
value="ognl:getMessages().getMessage(key)"/> <div jwcid="@If"
condition="ognl:class == 'required'"><span class="req">
*</span></label>
I'm pretty sure "class" won't work as a parameter name b/c I've
seen a stacktrace using this already. Regardless, let's pretend it
does (I've tried using other names). Here's the desired usage:
<label class="required desc" jwcid="@Label" for="phoneNumber"
key="user.phoneNumber">Phone Number</label> produces:
<label class="desc" jwcid="@Label" for="phoneNumber">Phone
Number<span class="req"> *</label>
I'm fine with the result having class="required desc" - I basically
just need some indicator to show a field is required when I'm not
wiring up it's input field as a component.
Issue #2
---------------------------
I'm overriding ValidationDelegate in order to add required field
indicators. I used to be pre-pending an asterisk to the beginning
of the field, and I had that working. Now I want to add <span
class="req"> to the end of the <label> before the </label> shows
up. I'm using @FieldLabel and everything *almost* works. I've
eliminating error styling in the class below so it's easier to read.
public class Validator extends ValidationDelegate {
public void writeLabelSuffix(IFormComponent component,
IMarkupWriter writer, IRequestCycle
cycle) {
if (component.isRequired()) {
writer.begin("span");
writer.attribute("class", "req");
writer.printRaw(" *");
writer.end();
}
}
The code above results in <label>blah blah</label><span
class="req"> *</span>, when I'd rather have the <span> w/in the
<label>. I tried overriding writeLabelAttributes(), but that
doesn't seem to allow me to create a new tag and write it out w/in
the label. Am I missing something here? Has anyone done something
like this - or knows how to add a <span> withing an @FieldLabel?
Thanks,
Matt
