Re: Validation problems for fields in iterator

I think, I found the solution by using the "visitor validator"=2E
Is that the right way?
<!-- Field Validator Syntax -->
    <field name=3D"mother=2Echild">
       <field-validator type=3D"visitor">
          <param name=3D"context">myPath=2EChildClass</param>
          <param name=3D"appendPrefix">true</param>
          <message/> Required even though missing in documentation https:/=
/struts=2Eapache=2Eorg/core-developers/visitor-validator
       </field-validator>
    </field>

And for the conversion error not repopulating the field:
Done with this syntax:
<s:textfield name=3D"mother=2Echild[%{#status=2Eindex}]=2Epocketmoney" val=
ue=3D"%{getFormatted('myDoubleFormat','mother=2Echild[' + #status=2Eindex +=
 ']=2Epocketmoney')}"
(This may be trivial for Struts experts but I am not=2E=2E yet=2E=2E=2E)

Only problem left:
2 field errors when entering 'x' for pocketmoney:
- raised by conversion error=20
- raised by required validator
Why is conversion error not sort of short-circuit to prevent further valid=
ation on that field?
(Most of my double fields are not required, so I want to keep the automati=
c=2E)

I tried to add a conversion validator with short-circuit=3D"true" but this=
 caused two identical field errors for the conversion error=2E
(In fact, two 'almost' identical field errors:
The "automatic" conversion error threw my translated xwork=2Edefault=2Einv=
alid=2Efieldvalue=3DUng=C3=BCltiger Wert im Feld ''{0}''=2E as Ung=C3=BClti=
ger Wert im Feld 'mother=2Echild[0]=2Epocketmoney'=2E
The xml conversion validator should have thrown another error but due to m=
y typo error also used xwork=2Edefault=2Einvalid=2Efieldvalue=3DUng=C3=BClt=
iger Wert im Feld ''{0}''=2E But on its way it lost the apostrophe (in Abst=
ractLocalizedTextProvider) and came out as Ung=C3=BCltiger Wert im Feld mot=
her=2Echild[0]=2Epocketmoney=2E )

I could not find a way to remove a field error from the field error=2E

Since this looks odd to users, I would appreciate any advice how you deal =
with this issue=2E

Best regards
Ute
