problem using the 1.1b2 validator dependency feature
I am running Struts 1.1b2 on Jboss 3.0.3 w/ Tomcat 4.1.12 with JDK 1.4.1
on Windows XP.
I have a form page that is validating nicely using required, maxlength,
integer, range, and mask validations on various fields. I want to
change a field so that it is only required if another field equals a
certain value.
I changed my validation.xml for the dependent field to look as follows,
<field property="field2" depends="requiredif,mask,maxlength">
<msg name="mask" key="errors.mask"/>
<arg0 key="myForm.field2.label"/>
<arg1 name="maxlength" key="${var:maxlength}" resource="false"/>
<var>
<var-name>mask</var-name>
<var-value>${defaultMask}</var-value>
</var>
<var>
<var-name>maxlength</var-name>
<var-value>20</var-value>
</var>
<var>
<var-name>field[0]</var-name>
<var-value>field1</var-value>
</var>
<var>
<var-name>field-test[0]</var-name>
<var-value>EQUAL</var-value>
</var>
<var>
<var-name>field-value[0]</var-name>
<var-value>myvalue</var-value>
</var>
</field>
where field1 is a hidden field that gets filled in at submit time before
the validation is called.
When I try to hit this page after making this change, I get the
following during page compilation...
[ServletException in:/content/register/register.jsp] null'
where the debug log indicates that a null pointer exception is thrown
when trying to generate the javascript.
2002-11-02 13:09:34,313 ERROR [org.jboss.web.localhost.Engine] -----
Root Cause -----
java.lang.NullPointerException
at
org.apache.struts.taglib.html.JavascriptValidatorTag.doStartTag(JavascriptValidatorTag.java:297)
at
org.apache.jsp.register_jsp._jspx_meth_html_javascript_0(register_jsp.java:1445)
at org.apache.jsp.register_jsp._jspService(register_jsp.java:558)
I thought this may indicate that I was missing a required key in my
ApplicationResources.properties, so I added an entry for
errors.requiredif, but no luck.
Am I missing something here?
Thanks
Eric

Re: problem using the 1.1b2 validator dependency feature
Posted by Eric Weidner <er...@ejbsolutions.com>.
I'm now using the 20021102 1.1 nightly build and I get the following
java script error when submitting the page.
Error: invalid assignment left-hand side
Source Code:
this.field-test[0]='NOTNULL'; this.maxlength='20';
this.field[0]='field1'; this.mask=/^[a-zA-Z0-9\-]*$/; return this[varName];
I get the same error trying to use EQUAL. This bombs all the validation.
The error message is from Mozilla, but the javascript fails in IE as well.
Any ideas?

Will do when I get time to write up a proper bug.

When downloading a struts version always refer to the version of the
docs that come with that download. The docs on the web site tend to
reflect functionality of the current nightly build.

I don't believe so, I had seen something mentioned in the news group
in the last week about that. If there is a problem then file a bugzilla
bug report.

Yes, this is truly 1.1b2 and that is the line that failed. I figured
the "requiredif" was in there since the documentation mentioned it as a
feature in 1.1. I'll get a nightly and try that.
BTW, was one of the bugs that was fixed validating max and min length on
password fields?
Thanks,
Eric

Is this truely Struts 1.1B2, or a nightly ?
The "requiredif" javascript method wasn't
added until Oct 18 or so. Mixing different
functionality from 1.1B2 & a nightly build
will get you unknown results and puzzled looks :-)!
Also the date of the commons-*.jars should
match the date of struts.

If it is truely 1.1B2 then it died at
String javascript = va.getJavascript();
I would try the nightly build. The validator
code has had about 6 bugs fixed sinse B2.
