Thats not exactly the situation... here a descreption depending on your code
snippet.
<form jwcid="@Form">
<div jwcid="@For" source="ognl:objects" value="ognl:currentValue">
<span jwcid="@If" condition="ognl:currentValue instanceof
StringColumn"
<input jwcid="@StringComponent"
value="ognl:currentValue"/>(includes Validation and further function)
</span>
<span jwcid="@If" condition="ognl:currentValue instanceof
DateColumn"
<input jwcid="@DateComponent" value="ognl:currentValue"/>
(includes Validation and further function)
</span>
</div>
<input jwcid="@Submit"/>
</form>
....
the Problem is that I don´t know how to check the Validation of each
component in the "doSubmit-Method". I need a way to iterate over the
"subcomponents"!?!?!
Maybe your way would work, but then it´s incosistent to my hierachy.
P.S. Thx for help.
