And unless you need some sort of very low level access to the
bindings, there is really very little reason to go to the extra
effort of a WODynamicElement. Stateless components are a better choice.

Hi list,
I am trying to create some of the components I use in my app as
dynamic elements. Though being quite successful I encountered a
problem I could not resolve: I created a dynamic component
"JWTable" that writes a html table tag and will have child elements
in it. Now I wrapped that element within a WOForm and added some
submit buttons as child elements of JWTable:
<webobject name = "WOForm1">
<webobject name = "JWTable1">
…
<tr>
<td>
<webobject name = "WOSubmitButton1" />
<webobject name = "WOSubmitButton2" />
</td>
</tr>
</webobject>
</webobject>
JWTable1 : JWTable {
}
WOForm1 : WOForm {
multipleSubmit = true;
}
WOSubmitButton1 : WOSubmitButton {
action = doOne;
value = "1";
}
WOSubmitButton2: WOSubmitButton {
action = doTwo;
value = "2";
}
Unfortunately when clicking a button the invokeAction of the main
component (that has the corresponding action methods implemented)
calls the invokeAction of the dynamic element (as the submit
buttons are children of it). But this results into the situation
that the action methods are not found and null is returned instead.
Is there any way to make WO call the actions in the parent without
hardcoding the functions (as then it wouldn't be a generic
component anymore)? Calling something as context.component
().invokeAction(…) doesn't help as this will bounce back the call
leading to an infinite loop. I did not find any example that covers
this case. Or do I have to implement JWTable as stateless component
instead?
