Gerhard Petracek commented on TRINIDAD-880:
-------------------------------------------
hello graeme,
thank you for updating the information!
the open issue (short description):
there is a ppr validation issue if the value of a required attribute changed in
the meantime (e.g. false -> true -> false).
workaround (in your case):
in my opinion it doesn't make sense to display a disabled input component which
doesn't provide information (a "default value")
-> use the rendered attribute instead of disabling the component.
(+ partialTriggers at a component above (e.g. at the parent) - you already
implemented a valid constellation)
regards,
gerhard

> Key: TRINIDAD-880
> URL: https://issues.apache.org/jira/browse/TRINIDAD-880
> Project: MyFaces Trinidad
> Issue Type: Bug
> Affects Versions: 1.2.3-core, 1.2.4-core, 1.2.5-core
> Environment: Windows XP Pro SP2, Facelets 1.1.13, Sun Java System
> Application Server 9.1, JSF1.2_07-b03
> Reporter: Graeme Steyn
> Attachments: TRINIDAD880.zip

> To reproduce the problem change the POM for the attached sample application
> to use Trinidad 1.2.5, build, deploy and execute the following sequence of
> actions.
> 1. All radio buttons should be blank when form is first displayed - press
> "Submit" - validation error occurs for first question (expected).
> 2. Select "Yes" for "Is English your first language?" - press "Submit" -
> validation error is cleared and form re-displayed.
> 3. Select "No" for "Is English your first language?" - press "Submit" -
> validation error occurs for second question (expected).
> 4. Select "Yes" for "Is English your first language?" - ppr results in second
> question being disabled, not required and clears validation message.
> 5. Press "Submit" - validation error occurs for second question (fault).
> 6. Select "No" for "Is English your first language?"
> 7. Select "Yes" for second question. Notice that a new required field
> appears.
> 8. Press "Submit" - validation error occurs for the new field (expected).
> 8. Select "No" for second question. The additional required field disappears.
> 9. Press "Submit" - Works as expected due to TRINIDAD-842 fix (Used to
> produce an error for core-1.2.3 and 1.2.4).
> 10. Select "Yes" for "Is English your first language?" - press "Submit" -
> validation error messages occurs for 2nd question (fault).
> Using Firebug, it appears that the ppr is taking place correctly, but
> checking the DOM for _english_Validators shows that all three validators are
> eventually listed.
> I am assuming that this is what is causing the problem, as when the lower two
> fields are disabled/hidden, the validators are not removed from
> _english_Validators.
> It appears that the problem may be related to "TRINIDAD-96 - Validators
> should be added incrementally, not set as a whole". The problem is not
> present in Trinidad 1.2.2,
> but does appear in 1.2.3, 1.2.4 and 1.2.5.
