Re: highlight invalid fields with custom Validation Framework?

2012-11-25 Thread James Selvakumar
Martin,

Thank you so much. I was exactly in the position where delta458 was and
almost got through with it.
After following your suggestions, the ValidationMsgBehavior looks like this:

pre
public class ValidationMsgBehavior extends Behavior
{
@Override
public void onRendered(Component c)
{
FormComponent fc = (FormComponent) c;
if (!fc.isValid()) {
String error;
if (fc.hasFeedbackMessage()) {
error =
fc.getFeedbackMessages().first(FeedbackMessage.ERROR).toString();
} else {
error = Your input is invalid.;
}
fc.getResponse().write(
div class=\validationErrorMessage\ + error +
/div);
}
}
}
/pre

I'm using Wicket 6.3.0 and there is no onRendered method in Behavior.
I should be using afterRender(Component component) now, right?
That will make this code compatible with the latest wicket version.

 fc.getFeedbackMessages().first(FeedbackMessage.LEVEL_ERROR).toString();

 Or you may use the default registered converter to transform it to
 String. But this is more advanced and most probably you don't need it.

 The source code is the best. It is really simple.

Re: highlight invalid fields with custom Validation Framework?

2012-10-15 Thread Bert
Hi,

are you looking for a generic way to highlight invalid components? If
so, have a look at
https://code.google.com/p/londonwicket/downloads/detail?name=LondonWicket-FormsWithFlair.pdf

as an inspiration point. Depending on the wicket version, you might
have to adopt the code a bit.

Hope that helps

 It would be great if you give me a short example on how to do that. Or links
 with good tutorials?

Since RequiredBorder is a behavior, you can just #add() it.

 c.add(new ValidationMsgBehavior());
 c.add(new ErrorHighlightBehavior());
 }
 *//CONTINUE_TRAVERSAL could not be found*
 return *IVisitor.CONTINUE_TRAVERSAL*;

IVisitor has been improved for Wicket 1.5.0.
Example:
new IVisitorComponent, Void()
{
public void component(final Component component, final 
IVisitVoid visit)
{
add(component);
visit.dontGoDeeper();
}
});

I.e. you need to use visit#XYZ methods to stop the visitor. Don't call
anything and it will continue.

 }

 private class RequiredBorder extends BorderBehavior {

 public void renderAfter(Component component) {
 FormComponent fc = (FormComponent) component;
 if (fc.isRequired()) {
 super.afterRender(component);
 }
 }
 }

 *//AbstractBehaviour could not be found*
 private class ValidationMsgBehavior extends *AbstractBehavior* {

AbstractBehavior is renamed to Behavior.


 public void onRendered(Component c) {
 FormComponent fc = (FormComponent) c;
 if (!fc.isValid()) {
 String error;
 if (fc.hasFeedbackMessage()) {
 *//getFeedbackMessage() could not be found*

 public void onComponentTag(Component c, ComponentTag tag) {
 FormComponent fc = (FormComponent) c;
 if (!fc.isValid()) {
 tag.put(class, error);
 }
 }
 }
 }

You face all these problems because you migrate code from version X to
version X + Y, where Y is  1, i.e. you need to read the migration
guides for all the steps.
Or just ask here and we will try to help you :-)

Re: highlight invalid fields with custom Validation Framework?

2012-10-15 Thread delta458
Alright, I have something like this now: Problems/Errors are *bold*
*
//Here is a problem with the class: it says: ShinyFormVisitor is not
abstract and does not override abstract method component(Object,IVisit) in
IVisitor*
public class *ShinyFormVisitor* implements IVisitor, Serializable {

Set visited = new HashSet();

*//Is that ok now? with IVisitor for wicket 6.0?*
public void component(final Component c, final IVisitVoid visit) {
if (!visited.contains(c)) {
visited.add(c);
c.add(new RequiredBorder());
c.add(new ValidationMsgBehavior());
c.add(new ErrorHighlightBehavior());
}
   visit.dontGoDeeper();
}

private class RequiredBorder extends BorderBehavior {

public void renderAfter(Component component) {
FormComponent fc = (FormComponent) component;
if (fc.isRequired()) {
super.afterRender(component);
}
}
}

private class ValidationMsgBehavior extends Behavior {

public void onRendered(Component c) {
FormComponent fc = (FormComponent) c;
if (!fc.isValid()) {
String error;
if (fc.hasFeedbackMessage()) {
*//getFeedbackMessage() could not be found*
error =
fc.*getFeedbackMessage()*.getMessage().toString();
} else {
error = Your input is invalid.;
}
fc.getResponse().write(
div class=\validationMsg\ + error + /div);
}
}
}

private class ErrorHighlightBehavior extends Behavior {

@Override
public void onComponentTag(Component c, ComponentTag tag) {
FormComponent fc = (FormComponent) c;
if (!fc.isValid()) {
tag.put(class, error);
}
}
}
}
