Solved: Check Box Group - Event Problem

Former Member · ‎03-17-2006

Hello,

I have put a CheckBoxGroup into my View and

I put a attribute of a varaible note to the texts property.

That works fine.

But when I put an action to the onToggle Event,

and after deploying click to one of the CheckBoxes

I become an "Internal Server Error".

Can anybody help me,

Patrick

It's 0..1

The Cardinality for the Selection1 Node is 0..n

In it is a Attribute called Names

I had addes to this Attribute dynamically Elements,

which come from a SQL database.

In the CheckboxGroup
