No error / warning when using @Component Form instead of BeanEditForm
---------------------------------------------------------------------
Key: TAPESTRY-2233
URL: https://issues.apache.org/jira/browse/TAPESTRY-2233
Project: Tapestry
Issue Type: Improvement
Components: tapestry-core
Reporter: Christoph Jäger
Priority: Minor
Fix For: 5.0.10
I just spent quite some time to find a bug in my code.
In my .tml I use a <t:BeanEditForm>. As soon as I added
@Component
private Form form;
to the corresponding .java file (need to do some validation), the form was no
longer rendered (the rest of the page was there, only the form was missing). Of
course, using
@Component
private BeanEditForm form;
instead fixes the problem.
It took me long to find the problem, because there was no hint of what I was
doing wrong. Maybe Tapestry could be enhanced to generate some kind of error
message or warning in case of such misaligned component classes, instead of
quietly dropping the form.
Of course, enhancing the system to be able to use Form instead of BeanEditForm
if you need just the basic features of Form, and not BeanEditForm in your java
code, would be even better, but this seems difficult, as Form is not a
super-class of BeanEditForm.
