FW: Scaffolding Phase 1 Complete

[Dierk König]

*hehe* very nice.

two points, though:
- running depends on Java 5 (so does compiling but that was already known)
- when posting a comment I get

   [script] OGNL error attempt to set 'entryId' to value '2' for object
'Comment@1cbcf91':Comment.entryId
   [script] ognl.NoSuchPropertyException: Comment.entryId

I will send you the whole log to your personal address since it is too large
for this listserver :-(

Great work!
Mittie

P.S. it's time I write a webtest for the blog sample...

Yeh I realise this, its related to WebFlow I believe (thanks for the

In fact I was going to migrate this code to use Spring's
ServletRequestBinder anyway.. so may as well do it

Actually this is normal.. probably I shouldn't be printing the stack
trace in this case.. what is happening is i'm using the request
parameter map to set properties on the domain class but it included an
additional property that didn't exist in said domain class hence the
error

because you have debug enabled it has printed the error out, but
really it is not an error.. I have changed it now to use the spring
binder instead though as this is a better approach

You were right, there were a few calls to Arrays.toString which is a
jdk 1.5 method.. this should be fixed now.. so at least you can run in
jdk 1.4 until we fix the WebFlow stuff

Hey Graeme,

What e-mail are you refering too? I responded to your question on
solving the 1.4 compilation problem.

Hi and a Happy New Year to everybody.

Some time ago we talked about having different controllers for
e.g. REST, XML-RPC, or SOAP services.

I'm happy to let you know that such controllers can be tested with
the latest version of Canoo WebTest.

see
http://webtest.canoo.com/webtest/manual/invoke.html
details with method='POST'

cheers
Mittie

[graemer]

Happy new year dierk, looks great btw.. I know you did some work
incorporating web test into the books sample app, but it would be
interesting to see how that could be incorporated into regular grails
unit tests or possibly by moving your WebTest.groovy class into the
core so it could be extended by anyone hence improving grails is
unit/functional testing support

What do you think?

Graeme

Yes, it would be very convenient to have this functionality
available for every grails-app.
Using WebTest for Grails will always need an extra
download/installation because of its size, but that can be
automated easily.
WebTest.groovy should go either to Grails or to WebTest.
ATM there are not a lot of Grails-specifics in it (only
grails_home if I remember correctly). That would call for
putting it into the WebTest distro.
We could also scaffold a WebTest structure for grails-apps.

Hi,

I find names like
 web2.3.xml.template
a bit unfortunate. I better like
 web2.3.template.xml
 bla.template.html
 blubs.template.sql
and such as it enables me to open it
with my according editor.

cheers
Mittie

[graemer]

Good idea Dierk.. thanks for the suggestion

Hi,

I tried to update the tests (they are pretty outdated) and came across this
behaviour: I tried to use Browser back from the details page, which asked
for re-POSTing, which I cancelled. After that the sample app could not be
used with
 grails run-app
any longer. Even after restart, connecting to localhost:8080/books/books
produced the stacktrace below.

cheers

Ah right.. thanks for the error report, this is because you can't
press back in a webflow (it gives you that flow execution state
error)... and I recently added code that wraps a
GroovyRuntimeException and displays lines numbers, a code snippets,
error diagnostics etc in the browser...

but it is obviously not taking into account web flows.. I will look at this

Thanks
Graeme

another finding from the tests is that on the books
details page
 bookAuthor
and
 bookTitle
appear at the wrong places
(see below).

another finding from the tests is that
when adding a new book with a new author that
new author is not picked up and neither displayed
in the overview nor in the details.
