I use IPortletURL Java Object to redirect and call a Action in target portlet,but failed.
Please help me to analysis the trouble…

in the souce porlet binding the following action to a command button control

public void htmlCommandButton_action() throws Exception{

IPortletURL refreshUrl = createActionUrl();

refreshUrl.clearParameters();
refreshUrl.clearState();

refreshUrl.setPortlet("/meta/default/link_portlet___targetpage/0000010988");
refreshUrl.setTargetAction("dammit");

Debug.info("redirectURL : " + refreshUrl.toString());
getFacesContext().getExternalContext().redirect(refreshUrl.toString());

}

the dammit action is in the target portlet

@PortletAction
public void dammit()
{
Debug.info("dammit");
}

but but when I click the Command Button , the page was not redirect,but the target action was be executed.

I check the message in full_log
[2013-04-27 23:52:18 CST (Framework:INFO) [RID:201] - redirectURL : /meta/default/link_portlet___sourcepage/0000010984?wmp_tc=10988&wmp_rt=action&wmp_ax=KkLTrr31MH4oUXW6Qhp5DYlDIWQ%3d&wmp_ta=dammit

2013-04-27 23:52:18 CST (Framework:INFO) [RID:202] - dammit ]
it shows that the target Action was be called successfull,but the page was still stay in source portlet,redirect failed!

To solve the problem,I modify the code

public void htmlCommandButton_action() throws Exception{

IPortletURL refreshUrl = createActionUrl();

refreshUrl.clearParameters();
refreshUrl.clearState();

//refreshUrl.setPortlet("/meta/default/link_portlet___targetpage/0000010988");
refreshUrl.setBaseURL("/meta/default/link_portlet___targetpage/0000010988");
refreshUrl.setTargetAction("dammit");

Debug.info("redirectURL : " + refreshUrl.toString());
getFacesContext().getExternalContext().redirect(refreshUrl.toString());

}

when i click the command button , the portlet redirect to the target portlet Successfully,but the action on target portlet called failed.

i check the full_log

the Chinese means invalid target Action
Let’s analysis together,and help me to solve the problem
thanks very much!

link_Portlet.zip (12.8 KB)

Please add another portlet url as a child. The parent url specifies the baseurl (if different from the current page/folder). The child url(s) are for each target portlet. Each child url may have 0-n parameters. Only one child url may specify an ‘action’.

For example:

IPortletURL refreshUrl = createActionUrl();

refreshUrl.clearParameters();
refreshUrl.clearState();

IPortletURL targetPortletUrl = refreshUrl.addPortletURL("/meta/default/link_portlet___targetpage/0000010988");
targetPortletUrl.setTargetAction("dammit");

Debug.info("redirectURL : " + refreshUrl.toString());
getFacesContext().getExternalContext().redirect(refreshUrl.toString());

thanks for Eric Norman’s advice
I update the code like Eric Norman said,but it’s still didn’t work,

/**
* Action Event Handler for the control with id='htmlCommandButton'
*/
public void htmlCommandButton_action() throws Exception{
IPortletURL refreshUrl = createActionUrl();  

refreshUrl.clearParameters();  
refreshUrl.clearState();

IPortletURL targetPortletUrl = refreshUrl.addPortletURL("/meta/default/link_portlet___targetpage/0000010988");  
targetPortletUrl.setTargetAction("dammit");  

Debug.info("redirectURL : " + refreshUrl.toString());  
getFacesContext().getExternalContext().redirect(refreshUrl.toString()); 

}

but when I click the command button ,the page was still not redirect,
I chek to full_log,

please tell me how to change the code to redirect from Portlet to another Portlet,and call the target action!

Sorry, my example was wrong. I forgot that the target action could only be set on the base portlet url. When using the ‘* Portlet URL’ UI controls it handles this automatically by moving the values to the right places.

So, to change to a new page and run an action on a portlet on the page the java code would have to look something like this:

public void htmlCommandButton_action() throws Exception{
IPortletURL refreshUrl = createActionUrl();  

refreshUrl.clearParameters();  
refreshUrl.clearState();

//navigate to the page that has the target portlet on it.
refreshUrl.setBaseURL("/portlet/link_portlet___targetpage");

//set the portlet that is the target of the action
refreshUrl.setPortlet("/portlet/link_portlet___targetpage");
refreshUrl.setTargetAction("dammit");

//redirect..
Debug.info("redirectURL : " + refreshUrl.toString());
getFacesContext().getExternalContext().redirect(refreshUrl.toString()); 

}

thank you very much!
I ask the same question on empower,but they said my environment is broken,That sounds too funny,hahah
