Using ValidField and Validator triggers null point exception
------------------------------------------------------------
Key: TAPESTRY-2139
URL: https://issues.apache.org/jira/browse/
TAPESTRY-2139
Project: Tapestry
Issue Type: Bug
Components: Framework
Affects Versions: 4.1
Environment: Macos X, java 1.4
Reporter: Numa Schmeder
Hello,
There is a small bug:
Description:
Using deprecated component ValidField, a validation bean
(IValidator), and enable javascript for this validator, then there
is a null pointer exception.
java.lang.NullPointerException
Stack Trace:
org.apache.tapestry.valid.BaseValidator.processValidatorScript
(BaseValidator.java:292)
org.apache.tapestry.valid.StringValidator.renderValidatorContribution
(StringValidator.java:109)
Test-Case:
--html--
<form jwcid="@Form" delegate="bean:delegate"
clientValidationEnabled="ognl:true">
<input jwcid="@ValidField" type="text" value="ognl:count"
validator="bean:requiredString" displayName="testField"/>
<input type="submit" value="Enregistrer"/>
</form>
--spec--
<bean name="requiredString"
class="org.apache.tapestry.valid.StringValidator,required,minimumLeng
th=10,clientScriptingEnabled">
</bean>
--java--
public String getMyName() {
System.out.println("get my name " );
return "Numa";
}
public abstract int getCount();
public abstract void setCount(int count);
Tested Solution:
Add the following lines to ValidField.java on line 90 in the
method renderComponent
//Add on 4.1, SetScriptSource was added in 4.1 but is never
called, so _scriptSource was never initialized
validator.setScriptSource(cycle.getInfrastructure
().getScriptSource());
//In case ClientValidationEnabled is set to the form set it also
to the Validator
if (getForm().isClientValidationEnabled() && validator
instanceof BaseValidator)
((BaseValidator)validator).setClientScriptingEnabled(true);
I know the component is deprecated, but still in my case I want to
migrate from 4.0 to 4.1 and I have more then 50 pages using forms
with ValidField, I don't to change all of them, but I would like
to take
the advantage of 4.1 for other pages...
Regards,
Numa
