[T5.1] No recursive component - Howto render Beaneditor in code?
Hi,
we have noted that T5 doesn't allow recursive components[1],
so we are currently doing something like this:
We reference our component in an arbritrary tml like this:
t:MyComponent
source=root
currentNode=currentNode
/t:MyComponent
The code stub of the component:
boolean setupRender(MarkupWriter writer) {
// write some opening div
}
void beforeRenderBody(MarkupWriter writer) {
processRoot(source, writer);
}
void cleanupRender(MarkupWriter writer) {
// close some opened div's
}
This works fine (#processRoot calls itself recursively for its children), but
now we
want to display a bean editor in a Node (in processRoot()). Is it possible to
reference
a component (like a bean editor) in a component being written in Java? Are
there any
examples how to achieve this?
TIA, Oliver

Re: [T5.1] No recursive component - Howto render Beaneditor in code?
Hi Ville,
thanks for your answer, but i didn't see how to do it. I will try to
explain my problem more in detail (sorry for my bad english):
We are using a component that is similar to [1] with the main difference
that we don't use a getTreeNodes, we use a getTreeRoot (e.g. single
element, not all elements of the tree) and doing our rendering inside the
java-component (we don't have a tml for our component) via the MarkupWriter.
The TreeDemo.tml from [1] allows to use a component 'Tree' like follows:
t:Tree treeid='literal:demo' source=treeNodes currentNode=node
t:actionlink t:id=tree context=node.identifier
${node.name}
/t:actionlink
/t:Tree
We can't use an actionlink because we only have a root node and iterate it
inside our java class (recursively via the processRoot method). Normally we
would like to do something like the following (TreeNode.tml):
div id=someid
t:if test=identifierEqualsX
t:beaneditor object=current/
p:else
current.name
/p:else
/t:if
t:loop source=current.children value=child
t:TreeNode element=child/
/t:loop
/div
but thats not allowed, e.g The template for component.. is recursive...
This is not supported so we are trying to do this inside a java class
(without a tml).
Now we want to render a beaneditor for a specific identifier inside the
java class, something like the following would be nice.
void processRoot(Node current, MarkupWriter writer) {
// open div
if (current.getIdentifier().equals(X)) {
---writer.renderBeaneditor(editor); ---
} else {
// display some informations of the node
}
for (Node child : current.getChildren()) {
processRoot(child, writer);
}
// close div
}
but i don't know how to add/declare/instanciate the beaneditor?
Thanks for any hints!
Oliver

Hi,
@InjectComponent injects the component defined in tml, @Component injects
instance that is configured by the annotation itself (and the associated tml
if it is defined there also).

T5.1 (Event)Context in a grid with additional column of checkboxes
Hi, i would like to to pass a context to a pagelink like a t:type=pagelink t:page=MyPage t:context=myContext but this only works if the returned values of myContext does not change after the page has loaded. More precisely i want to do something like jumpstarts Grid With Delete Column without a huge onSuccess method that passes values to a lot of @InjectPage annotated pages. Each of my pages already uses onActivate(EventContext eventContext) so i would prefer to use this way, but i don't know how. Is there a easy way to achieve this?

Hello,
i have some problems with the submit component and the parameter t:image.
The following works fine with T5.1.0.5
form t:type=form t:id=myform
input type=submit t:type=submit t:id=viewselection title=View/
/form
and as expected the following methods are called
@OnEvent(component=viewselection, value = EventConstants.SELECTED)
void someMethodName() {
logger.debug(With EventConstants);
}
void onSelectedFromViewselection() {
logger.debug(With onSelectedFromId);
}
@OnEvent(value = selected, component = viewselection)
void someOtherMethodName() {
logger.debug(With @OnEvent);
}
but if i want to use an image for the submit none of those methods are called
(the image will be rendered correctly).
I've used each of the following
input type=submit t:type=submit t:id=viewselection title=View
t:image=context:images/view.png/
input type=submit t:type=submit t:id=viewselection title=View
t:image=context:images/view.png/
t:submit t:id=viewselection title=view t:image=context:images/view.png/
Whats wrong?
TIA,
Oliver
