'this.values[...].value' is null or not an object

[chapp007]

Hi,

I keep getting the following error message when I type into the
dropdown component:

'this.values[...].value' is null or not an object

I am using IE8 in compatibility mode. The up and down arrows seem to
work.

The one weird thing that I am doing is that I am recreating the
dropdown after the page has been rendered when the user clicks a
SubmitLink(i.e. in the onSubmit method I am calling
MarkupContainer.replace). I have a simple page where I have just the
dropdown and two links and it seems to work properly. However in my
"real" page it doesn't. When I view source in the browser after
clicking the SubmitLink it does appear to be rendering the javascript
array of VisuralDataSourceValue objects correctly.

Any help is greatly appreciated.

Thanks,

Josh

Hi Josh,

The DropDownDataSource is not designed to be dynamic and replace() is untested with this component. 

I've raised a placeholder enhancement at http://code.google.com/p/visural-wicket/issues/detail?id=83 for this, as it is functionality which has been requested by others.

Not sure whether it will be in a release in the short term or not. The DropDown control is due for some major work soon though.

cheers,

Rich
