Error using "Portlet Embed" in Gadget

Hi All,

I have a requirement to provide a form in a UI, so I have first created a portlet and added it to a CAF Page. But as Business Console UI will have a rich look, I wanted to create a Gadget and Embed the same portlet in it. I have seen one of the controls in the pallette “Portlet Embed” and selected the portlet type as the portlet which I want to use but upon rendering it in AppSpace, I get the below error as “Portlet “caf.war.UserTasks.formdata.FormData@597f67e8” is not found”, where as I have added the same portlet to a page and its rendered correctly.

Could anyone tell what could be the issue? Below is the full error and attached the screenshot from view.xhtml

Thank you!

Portlet embed in Gadgets is not supported.

-Vinay

Hi Vinay,

Thanks for the response.

The reason I wanted to embed portlet in gadget is that there are some webservice invocations happening in the initialize method of portlet and I am not sure how I can do the same in a gadget form.

Do you know how I can invoke webservice from controller.js of gadget and map the response to UI elements and where I can store the credentials for invoking the webservice?

Thanks,
Irfan

Hi Irfan ,

This might be late reply to your post but you can invoke rest webservice in your controller.js . The rest call will return you response in JSON format which you can parse to render the page or to show the output.

Thanks

Hi Shrikant,

Thanks for the response.

Indeed we can do it using rest calls, but i wasnt aware at the time of posting the question about how to achieve it.

But, i figured it out eventually. Thanks :slight_smile:

Irfan
