Looking at the code, it looks like it should work. WOKeyValueAssociation.setValue() does the validation and calls that method. Is it calling it on a different component than in the first example?

Subject: Esoteric issue with automatic property validation and validationFailedWithException()

Hello,

Let’s say I have a Page component. On this page is a subcomponent, MyText, that looks like this in Page’s template:

<wo:MyText value="$item.content" />

And then MyText itself is just this:

<wo:text value="$^value"></wo:text>

Item.content is a String, and allowsNull is N in the model. So, obviously, it’s a candidate for automatic EOF property validation on form submission. When I leave the textarea blank and submit, validationFailedWithException() is called on the page—great.

But that’s not quite what MyText looks like—say I need to do other things with the bound string. So it actually looks like this:

<wo:text value="$value"></wo:text>

and has a couple of accessor methods instead:

public String value() {

return stringValueForBinding("value");

}

public void setValue(String value) {

setValueForBinding(value, "value");

}

Now, when I submit a blank textarea, validationFailedWithException() is _not_ called on the page. What’s going on here? What have I stomped on? How do I trigger automatic property validation with a component like this?
