OGNL bug and the new [2.3.1] click release
Hello,
Currently I am working on a dynamic form component ( which extends Form
class).
The idea is to build Form control on the basis of beans's fields ( that
have getter/setter methods) declared as a model.
So I added my own annotation and the dynamic form works fine,
The problem is when i try to copy form values to the bean object - it
raises strange exception, because object has required methods:
[Click] [debug] Error incurred invoking CarOption.id with null error: *
ognl.MethodFailedException*: Method "setId" failed for object
pl.mypackage.model.CarOption@523df [java.lang.IllegalAccessException:
Method [public void pl.mypackage.model.CarOption.setId(java.lang.Long)]
cannot be accessed.]
Then I tried to get the sources from repository... and the bug disappeared
( due to the exchange of ognl to mvel ?? )
and the version of click was changed.
My problem was solved itself, so what is my question? :)
Is it official 2.3.1 release or not yet?
Best regards,
Tomasz

Hello
Tomasz i think that your idea on creating dynamic form based on
annotations is great. Maybe you could share some of your code, so more
people could use it and help you
with extending this solution. What do you think about it?
Best regards

Hello,
Maybe one of the issue is as presented below ( unfortunately I cannot check
it with MVEL sources but it looks like the reason is the null value of one
of my bean field)
regards
Tomasz
After upgrading 2.3.0 to snapshot( 2.3.1) the error occures on a page which
list the data from the db.
[Click] [error] handleException: java.lang.RuntimeException: [Error: unable
to access field]
[Near : {... Unknown ....}]

Hi,
Click 2.3.1 is not release, hopefully by the end of the year it will
be available. MVEL replacement of OGNL still has a number of issues
which need to be resolved.
