I wrote the code in gmail, without the benefit of autocomplete or compile
errors.  What I'm really getting at is that you should *always* add the
attribute modifier, which takes a model for the value to set the attribute
to.  The model (either Model or AbstractReadOnlyModel, although the latter
is more appropriate for this) should then return the correct value based on
the logic

Re: How to remove css class from a component?

2010-06-15 Thread David Chang

>>Use a model like it's intended?

You mean I should use AbstractReadOnlyModel?

>>protected void onBeforeRender() {
super.onBeforeRender();
inputComponent.add(new SimpleAttributeModifier("class", true, new
AbstractReadOnlyModel() {
public String getObject() {
return inputComponent.getFeedbackMessage() != null
? "errorField" : "";
}
});
}

There is no such constructor forSimpleAttributeModifier.

Thanks.

Re: How to remove css class from a component?

2010-06-15 Thread Zoltan Luspai


Hi,

Two alternative solutions:

- If you want the CSS class be appened only in one response then set the 
AttributeAppender as "temporary"

...new AttributeAppender(...) {
@Override
isTemporary() { return true} }
}...
- Or disable/enable AttributeAppender as needed by overriding 
isEnabled() method of it:

...new AttributeAppender(...) {
@Override
isEnabled() { return inputComponent.getFeedbackMessage() != null }
}...


Cheers,
Zoltan

How to remove css class from a component?

Hello,

I add a CSS class to component dynamcially the following way:

inputComponent.add(new AttributeAppender("class", new 
Model("errorField"), " "));
