Configure an action for the execution of a chain
Hi,
I configured a chain like the following:
<chain id="minimum_chain">
<operation id="Seam.AddInfoMessage">
<param type="string" name="message">Success.</param>
</operation>
</chain>
Additionally I configured in another component/extension file the according action:
<action id="Chain.minimum_chain" link="" enabled="true" order="20"
label="minimum.chain" icon="/icons/action_add.gif">
<category>SUBVIEW_UPPER_LIST</category>
<filter id="newProjectAck">
<rule grant="true">
<permission>AddChildren</permission>
<type>Project</type>
</rule>
</filter>
</action>
The button is displayed correctly. I can click the button and the page reloads but nothing happens. I have no errors in the server log and it looks like nothing happens at all. I created a minimal chain to test my understanding of the mechanism but it looks like there is a missing link.
Any ideas what's wrong?
I don't find an example in the documentation which shows how to connect an action with an operation chain.
Best regards, Michael

In the <action> element you should use:
link="#{operationActionBean.doOperation('your.chain.name')}"

The behaviour does not change. The page reloads but I don't see the message. The file server.log does not report any problems.
BUT I added another operation to the chain - Seam.CreateDocumentForm. This operation succeeds now. Only the message from Seam.AddInfoMessage is not visible which means perhaps that I don't understand the operation.
