Custom Document Library Action Evaluator

Custom Evaluator for Document Library Action

Sometimes we need to show certain custom action on specified type of content only. Not all content show that custom action, because we need to evaluate to certain actions only.

This example explain simple custom evaluator in alfresco 4 share document library in which I want to display my custom action only on clm:Draft kind of type content only.

To make this enable we need to modify following files:

1. share-config-custom.xml
2. custom-slingshot-application-context.xml

1. share-config-custom.xml

This file contains custom action and actionGroup entry.

Action entry contains information about the new custom link we are adding to action like below:

<actions>

<action id="folder-assign-workflow" type="pagelink" icon="folder-manage-permissions" label="Start Draft Workflow">
<param name="page">documentlibrary?nodeRef={node.nodeRef}</param>
<evaluator>evaluator.doclib.action.draftTypeFolder</evaluator>
</action>
</actions>

ActionGroup is the group in which we are adding our custom action entry

<actionGroups>

<actionGroup id="folder-browse">

<action index="161" id="folder-assign-workflow" />

</actionGroup>

</actionGroups>

So total entry looks like below :

<config evaluator="string-compare" condition="DocLibActions"> 
<actions> 
<action id="folder-assign-workflow" type="pagelink" icon="folder-manage-permissions" label="Start Draft Workflow"> 
<param name="page">documentlibrary?nodeRef={node.nodeRef}</param> 
<evaluator>evaluator.doclib.action.draftTypeFolder</evaluator> 
</action> 
</actions> 
<actionGroups> 
<actionGroup id="folder-browse"> 
<action index="161" id="folder-assign-workflow" /> 
</actionGroup> 
</actionGroups> 
</config>

2. custom-slingshot-application-context.xml

This file contains evaluator entry.

<bean id="evaluator.doclib.action.draftTypeFolder" parent="evaluator.doclib.action.nodeType">
<property name="types">
<list>
<value>clm:Draft</value>
</list>
</property>
</bean>
