Hi Kannan,

I don't see a reason why the third point should give you any troubles.
It simply asks for you to add the proper tag at the right place in liferay-portlet.xml .

Here,have a look at my custom portlet's liferay-portlet.xml , You might be able to spot something.

<portlet>
		<portlet-name>newportlet</portlet-name>
		<icon>/icon.png</icon>
		<asset-renderer-factory>com.test.asset.AnnouncementAssetRendererFactory</asset-renderer-factory>
		<workflow-handler>com.test.workflow.AnnouncementWorkflowHandler
		</workflow-handler>
		<instanceable>false</instanceable>
		<header-portlet-css>/css/main.css</header-portlet-css>
		<footer-portlet-javascript>
			/js/main.js
		</footer-portlet-javascript>
		<css-class-wrapper>newportlet-portlet</css-class-wrapper>
		<add-default-resource>true</add-default-resource>	
	</portlet>

keep in mind that the tags should be in their respective places.

H2H,
Pawan Chauhan.

Hi Pawan Chauhan

I got it. I am using friendly URL tags in that portlet and because of that its not allowing me to place the workflow-handler tag after the icon tag. Is there any solution???

regards
Kannan

[pawan chauhan, modificado 10 Anos atrás.]

Hi Kannan,

Try this,

                    <icon>/icon.png</icon>
<friendly-url-mapper-class>  </friendly-url-mapper-class>
<friendly-url-mapping></friendly-url-mapping>
<friendly-url-routes></friendly-url-routes>
		
		<asset-renderer-factory></asset-renderer-factory>
		<workflow-handler></workflow-handler>

you might wanna have a look here too,

H2H,
Pawan Chauhan.

[Kannan G krishnan, modificado 10 Anos atrás.]

Hi pawan

I tried this one. But after saving the liferay-portlet.xml file i am getting the same error. Can you help me with an implementation example of this workflow.

regards
kannan

[pawan chauhan, modificado 10 Anos atrás.]

Hi Kannan,

You get an error right there or you get the error after deployment.
I don't get any error in IDE when follow this order.
In case of deployment error , kindly share it here.

Regards,
Pawan Chauhan.

Can u help me with your AnnouncementWorkflowHandler class

regards
kannan

[pawan chauhan, modificado 10 Anos atrás.]

okay lets go step by step.

1> Do you get an error prompt in IDE?
2>If yes what does it say?
3>Is your Workflowhandler class at proper place and is it proper?

Regards,
Pawan Chauhan.

[Kannan G krishnan, modificado 10 Anos atrás.]

Yes i am getting the same error as per my last post. I have just created a ArticleWorkflowHandler class and overrided the methods
- String getClassName()
- String getType(Locale locale)
- Object updateStatus(int status,Map workflowContext)
- String getIconPath(ThemeDisplay themeDisplay)

i didn't modified anything in this methods.

kannan

Hi Kannan,

Did you find the solution for Kaleo implemenation. I am also finding the same exception on console. I am implementing Kaleo worklow with a custom portlet. I followed the all steps. The portlet is not getting deployed after adding Handler class in liferay-portlet.xml Please suggest.

Thanks,
Prashant

Have a look at http://www.liferayzone.com/2013/11/kaleo-workflow-configuration-for-custom.html

[Prashant Chandra, modificado 10 Anos atrás.]

Hi Harish,

I followed the same step , but getting the exception and the portlet is not getting deployed. Please suggest..

Harish,

Got it!! Resolved the exceptions. Thanks for your help!!

Thanks,
Prashant

[Kannan G krishnan, modificado 10 Anos atrás.]

Hi
You will be getting the exceptions because of the following reasons.
1. Any of the classes you are using as the workflow handler or AssetRenderer and AssetRendererFactory is not properly extended with the required classes.
2. Wrong class names mentioned in the liferay-portlet.xml.
For example, in liferay-portlet.xml in between the icon and instanceable you will be mentioning the lines,

<icon>/icon.png</icon>
<asset-renderer-factory>com.liferay.admin.asset.TestAssetRendererFactory</asset-renderer-factory>
<workflow-handler>com.liferay.workflow.TestWorkflowHandler</workflow-handler>
<instanceable>false</instanceable>

Please check the names that you mentioned are correct.

Regards
Kannan

Hi Harish,

I am customizing the Kaleo implementation in custom portlet. serviceContext.getModifiedDate() returns NULL.
feedback.setStatusDate(serviceContext.getModifiedDate());

Please suggest.

Thanks,
Prashant
