ApexPages.currentPage().getParameters in ApexComponent and in Visualpage are different?

Question

I am trying to pass url parameters between Apexpages and component but am not successful in achieving this. When I call ApexPages.currentPage.getParameters().put('test','aaa')

in a pagecontroller and then call ApexPage.currentPage.getParameters().get('test') in a component controller which resides in that page. The method returns nothing. Can someone tell me how can I persist the url parameters between page controller and component controller?

thank you

Answer 1

I think your question was unclear. You said that the value needs to be pass from the page to controller.but if the value is dynamic then you have to workaround on <apex:param> tag.

If you are passing the parameters like ID then You have to append the URL of vf page with your ID and value like below

https://yourdomainname/apex/vfpagename?test=value

And get the parameter in the controller using

ApexPages.currentPage.getParameters().get('test');

Hope this might helps....

You can use like this:

PageReference pageRef = ApexPages.currentPage();

pageRef.getParameters().put('test', ApexPages.currentPage().getParameters().get('test'));

pageRef.setRedirect(true);

return pageRef;
