Ok I tried it very often ... and it looked like that
page:
...
<span jwcid="@Foreach" source="ognl:MyList" value="ognl:TemporaryItem"
index="ognl:Index">
<span jwcid="@If" condition="ognl:MyClass">
<span jwcid="@MyFormComponent"
item="ognl:TemporaryItem"/>
</span>
</span>
...
myformcomponent.jwc
...
<component id="putitin" type="TextArea">
<binding name="value" value="ognl:item.content"/>
</component>
<!-- Parameter -->
<parameter name="item" required="yes"/>
...
myformcomponent.html
<form jwcid="[EMAIL PROTECTED]" listener="listener:formSubmit">
<textarea jwcid="putitin" cols="70" rows="10">
Content...
</textarea>
<input type="submit" value="Send"/>
</form>
Reading the Parameter was no problem but when I submit the form i get an
"setProperty(null,content,"my new value exception)"... I my eyes it looks
like that the binding wasn´t successfull.
I read several forum-messages ... some of them with the same problem. They
all give the parameter to a persistent property.
