RE: Problem with AssetRenderer.getURLViewInContext() in 7.2 ?

2022-06-30T19:12:00Z

Try adding a widget page containing a portlet. Such as blogs, I was trying to show blog entries in asset publisher and it'll only work now for view-in-context if there is a context existing (context means page).

Example I had to do this to avoid the error:
<#assign viewURL = assetRenderer.getURLViewInContext(renderRequest, renderResponse, viewURL)!"http://www.50shades-o-liferay.com/oddity-base/find-urls-need-pages-to-exist-with-portlets-to-return-a-url.html" />

The view in context URL looks something like ...
http://localhost:8080/c/blogs/find_entry?p_l_id=67&noSuchEntryRedirect=null&entryId=88020

Problem with AssetRenderer.getURLViewInContext() in 7.2 ?

We have a custom search portlet that displays links to the results using URLs generated by AssetRenderer. Here is a sample of the code:

String urlMaximzed = renderer.getURLView((LiferayPortletResponse) actionResponse, WindowState.MAXIMIZED);

String urlviewincontext = renderer.getURLViewInContext((LiferayPortletRequest) actionRequest, LiferayPortletResponse) actionResponse, null);

Printing out these URLs gives:

2021-10-26 18:27:55.739 INFO [http-nio-8080-exec-4][CustomSearchPortlet:740] searchDocuments: urlMaximized: http://localhost:8080/web/avengers/search?p_p_id=com_liferay_document_library_web_portlet_DLPortlet&p_p_lifecycle=0&p_p_state=maximized&p_p_mode=view&_com_liferay_document_library_web_portlet_DLPortlet_mvcRenderCommandName=%2Fdocument_library%2Fview_file_entry&_com_liferay_document_library_web_portlet_DLPortlet_fileEntryId=35816

2021-10-26 18:27:55.742 INFO [http-nio-8080-exec-4][CustomSearchPortlet:755] searchDocuments: urlviewincontext = http://localhost:8080/c/document_library/find_file_entry?p_l_id=20&noSuchEntryRedirect=null&fileEntryId=35816

Clicking on the first URL (maximized) in the portlet seems to work fine for all asset types. Clicking on the second (view in context) works for assets other than documents. For documents, clicking on the link produces an error with the following stack trace:

All of this worked correctly in 6.x, we're just seeing it now as we're migrating to 7.2.

For brevity, AssetRenderer.getURLView returns a URL that works correctly. So does AssetRenderer.getURLExport. Only AssetRenderer.getURLViewInContext is returning a bad URL.
