Hi List,
i'am working on a workflow like application which provides distributed
users the possibilty to work on a common piece of work (case). A case is
divided in a couple of tasks which are actually simple forms a user has
to deal with. To display these task forms i'am using the BeanEditForm
component. At this, a TaskDataFactory provides the current taskdata Bean
- - depending on the case state - to the BeanEditForm component.
For the first form everything works fine but if i try to enter the page
the second time (where it should display the form data for the next
state) i get a
org.apache.tapestry.ioc.internal.util.TapestryException:
Failure reading parameter value of component
core/PropertyEditBlocks:textfield: net.agef.ccm_2.entities.FinishData
I already checked the factory, which provides a valid instance of the
mentioned bean 'FinishData'. Is there maybe a problem with reusing a
page with different bean objects in connection with the BeanEditForm
component? You will find code snippet and stack trace attached.
Help is higly appreciated ..... ;-)
thx Andreas
