I spend some time learning more about this lenient thing and meanwhile I use
a current developer version (about two hours old) for my application.
But still it doesn't work :-( Maybe somebody can explain what I'm doing
wrong. I have something like this:
woody binding:
<wb:value id="vn_titel" path="v:Titel" lenient="true"/>
woody field:
<wd:field id="vn_titel" required="false">
<wd:label>Titel</wd:label>
<wd:datatype base="string"/>
</wd:field>
On submit I get the following exception:
org.apache.commons.jxpath.JXPathException: Exception trying to create xpath
v:Titel; Factory is not set on the JXPathContext - cannot create path:
/soap-env:Envelope[1]/soap-env:Body[1]/v:Versicherung[1]/v:Partner[1]/v:Pers
on[1]
Though it was recognized that the v:Titel node is not present in my source
file. But what's my mistake? I also tried to set the lenient attribute on
the parent context element but I still get the exception.
I need your help because this feature is very basic for me.
Thanks for your help.
