Jsp page with ui action to start specific workflow

[mohammed_amr]

Dears,

This question is repeated and there is no help till now !

I'm trying to build a dashlet on the alfresco explorer 3.4.d contains button with an action to start a workflow; once workflow has been started the alfresco explorer must transfer the user interface to the first step in the workflow.

How can i achieve this task and if you don't how can any one give me a hint !!

Thanks

Dears,

I got the solution and is as follow:

- create a jsp page as dashelt (you can refer to how to write simple jsp as dashlet).
- use alfresco faces components such as (a:actionLink) which is exist in the alfresco.tld
- create a managed bean and register this bean in the faces-config-custom.xml and you can optionally point to another benefits managed bean such as NavigationBean using #{NavigationBean} tag.

This is a full example for my bean :
