Thanks for this hint.
During further tests after my mail, I found a situtation where the
convertToString is called, but not the convertToObject. The initial
situation is the same as described in the first mail. Then the model is
updated by an ajax-call from null to a value, the output call my
ToString-Method, but a later form submit doesn't call the
ToObject-Method. It seems the problem occurs in
AbstractTextComponent.resolveType. This function tries only once to
resolve the type. In the first call the function sets type to null.
This is not my problem anymore. I can solve my special problem with the
IObjectClassAwareModel.

Without type there can't be a converter.

Hello!
I've got a problem with a TextField and the depending
CustomConverter. The converter of the component is not been called.
So the default converter takes the task and fails.
In my case this problem occurs when my IModel.getObject returns null.
The problem arises in the FormComponent.convertInput method. Because
of the null value, the typeName is null and a generic typcast is made
and fails. Shouldn't there be a pre-examination wheter a component
converter is available?
If I explicitly set a type through TextField.setType my converter is
called correctly.
Is that behaviour intended this way?
