[jira] Commented: (TAPESTRY-2139) Using ValidField and Validator
triggers null point exception
[ https://issues.apache.org/jira/browse/TAPESTRY-2139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12567033#action_12567033 ]
Numa Schmeder commented on TAPESTRY-2139:
-----------------------------------------
The code I gave fixes the problem in the java files but not all, for the javascript file.
I am working on correcting the javascript files of every validator.

> 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,minimumLength=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
