Hi All
I need to validate (within the CForms framework) that a set of
checkboxes have all been checked.
I have tried adding <fd:validation/> but it does not appear to
have
an
effect :
Checked the source: it's indeed not supported. Probably for no
particular reason.
Possible options are:
* adding support for it.
sounds good
Should be no more then adding the following
line to the class BooleanFieldDefinitionBuilder:
setValidators(widgetElement, definition);
I don't have time to test that, but since you already have an
example
worked out you could give it a try.
OK, I added setValidators(widgetElement, definition); at line 34,
in
the buildWidgetDefinition method.
I then test with the following booleanfield:
<fd:booleanfield id="mod-copyright">
<fd:label>
<i18n:text
i18n:catalogue="local">moderate.mod-copyright.label</i18n:text>:
</fd:label>
<fd:hint>
<i18n:text
i18n:catalogue="local">moderate.mod-copyright.hint</i18n:text>
</fd:hint>
<fd:help>
<i18n:text
i18n:catalogue="local">moderate.mod-copyright.help</i18n:text>
</fd:help>
<fd:validation>
<fd:assert test="mod-copyright = True()">
<fd:failmessage>
<i18n:text
i18n:catalogue="local">moderate.mod-copyright.fail</i18n:text>
</fd:failmessage>
</fd:assert>
</fd:validation>
</fd:booleanfield>
When I submit this form with the checkbox unchecked, I get no
validation error displayed.
Comparing Field to BooleanField, it looks like BooleanField needs
to
implement ValidationErrorAware, so I will try that next.
I also see that the class BooleanField defines the validate method
to
do
nothing. Just throw that method out (the one from the parent class
will
take over).
Yes.
What I cannot work out now is how to do the actual validation.
Nothing special needs to be done, it is handled by the validate
method
of the superclass.
Looking at Field.java, it uses the Datatype to do this:
validationError = getDatatype().validate(value, new
ExpressionContextImpl(this));
But BooleanField has no datatype .....
validators belonging to the datatype is old stuff (will be removed),
so
you can ignore that.
OK, I added the following to BooleanField :
implements ValidationErrorAware
protected ValidationError validationError;
public boolean validate() {
return super.validate();
}
public ValidationError getValidationError() {
return validationError;
}
public void setValidationError(ValidationError error) {
this.validationError = error;
}
I now get a ClassCastException when I submit. So I am stumped again.
Unfortunately, and I know how rude this sounds, but I have been asked
to get on with "other work", so unfortunately I will have to get back
to this later. My apologies, and thanks for the help so far.
Absolutely no problem. However, I think I fixed the source of the
problem with a new xreporter-expression jar I just committed.
Many thanks.
I will look at it asap.
regards Jeremy
