Passing string parameter to action in folder rules

mmrvelj

Hi all. 

I have created a Java class that extends ActionExecuterAbstractBase and exposes some properties (String values) through setters (in this example setApprovedText) that can be set. 

Then I registered it in a service-context.xml like this example:

<bean id="approve-document-action"
     class="com.alfresco.ApproveDocument"
     parent="action-executer">
   <property name="serviceRegistry" ref="ServiceRegistry"/>
   <property name="nodeService" ref="NodeService" />
   <property name="publicAction">
      <value>true</value>
   </property>
   <property name="approvedText" value="${digitalsign.approvedtext}" />
</bean>

Then I can register this value in alfresco-global.properties

digitalsign.approvedtext=APPROVED 

This all works fine, but in some cases is would be much better if I could provide this value as an action rule parameter.

Basically when I create rule on a folder, and when I choose action to perform, I would like to have field where I could provide this parameter value. Is this possible, and if yes - how can it be done?

Not exatcly sure how you have setup. Mostly likely your 'messages' (e.g. action-messages.properties) which has the labels defined, are not getting loaded by the time action class bean is initialized and 'addParameterDefinitions' method is inovked. By default bean scope is singleton, hence spring container initializes them at application startup time, so it depends how you have defined beans in the context file.

Try these steps, i am updating the method provided earlier:

@Override
protected void addParameterDefinitions(final List<ParameterDefinition> paramDefinitions) {
	paramDefinitions.add(new ParameterDefinitionImpl(PARAM_COMMENT, DataTypeDefinition.TEXT,
			true, getParamDisplayLabel(PARAM_COMMENT))); 
}

When getParamDisplayLabel method is called, it will try to load the label using I18NUtil, see the method impl below:

protected String getParamDisplayLabel(String paramName) {
  //<actionName>.<paramName>.display-label
  //e.g. update-comments.comment.display-label
  return I18NUtil.getMessage(this.name + "." + paramName + "." + DISPLAY_LABEL);
}

Add the labels as necessary, example:

#This is used to show param label
update-comments.comment.display-label=A Comment
#This is used to show Action tile/name in the actions list in rule configuration
update-comments.title=Update Comments

Now most importantly, make sure that message resource bundle bean is initialized in first place then all actions etc., See the details here

e.g.

<bean id="com.demo.resourceBundle" class="org.alfresco.i18n.ResourceBundleBootstrapComponent">
  <property name="resourceBundles">
     <list>
        <value>alfresco/module/${project.artifactId}/messages/action-messages</value>
     </list>
  </property>
</bean>

<bean id="update-comments" class="com.demo.action.UpdateCommentsActionDemo" parent="action-executer">
   <property name="publicAction">
     <value>true</value>
   </property>
   <constructor-arg ref="ServiceRegistry" />
</bean>
