Thanks for your thoughts.
I just discovered the following:
I did not check logs/catalina.out before.
It told me there is a problem with my datasource definition.
In fact I added the definition before coming back to the testing cycle,
where I am stuck now.
This seems to be totally unrelated at first glance, since data would be
stored much later into the session.
But apparently the initialisation is done at precisely that moment.
So I will try and repair this first and then come back if the problem
persists.
Anyway, here is my validation.xml, comments stripped.
For now it has just one form.
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE form-validation PUBLIC
"-//Apache Software Foundation//DTD Commons Validator Rules
Configuration 1.0//EN"
"http://jakarta.apache.org/commons/dtds/validator_1_0.dtd";>
<form-validation>
<formset>
<form name="TAform">
<field
property="transportnr"
depends="required,mask">
<arg0 key="prompt.tajsp.transportnr"/>
<var>
<var-name>mask</var-name>
<var-value>^(D11|K11|BWT|EBT|C11|BWC|EBC)K9\d{5}$</var-value>
</var>
</field>
<field
property="anforderer"
depends="required">
<arg0 key="prompt.tajsp.anforderer"/>
</field>
<field
property="wann"
depends="required">
<arg0 key="prompt.tajsp.zeitpunkt"/>
</field>
<field
property="transportweg"
depends="required">
<arg0 key="prompt.tajsp.trweg"/>
</field>
</form>
</formset>
</form-validation>

Wolfgang,
Can you post some of your validation file's form definition for "TAform"?
Any change your validation file's form isn't exactly spelled "TAform" (small
"F"?)?
Regards,
David

Subject: AW: nullpointer in struts-tag
On my previous posting I missed the fact that the error happens in
JavascriptValidatorTag,
which was my issue all along. It made me upgrade from Struts 1.1 to 1.2.4 in
the first place.
java.lang.NullPointerException
at
org.apache.struts.taglib.html.JavascriptValidatorTag.renderJavascript(Javasc
riptValidatorTag.java:358)
at
org.apache.struts.taglib.html.JavascriptValidatorTag.doStartTag(JavascriptVa
lidatorTag.java:333)
at
org.apache.jsp.TA_jsp._jspx_meth_html_javascript_0(TA_jsp.java:212)
at org.apache.jsp.TA_jsp._jspx_meth_html_html_0(TA_jsp.java:135)
at org.apache.jsp.TA_jsp._jspService(TA_jsp.java:99)
at
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:137)
Again, any hints where or what I should look at?
Mit freundlichen Grüßen
