[TYPO3-mvc] Reuse arguments in different action

[Stephan Schuler]

Hey there.

That only works in a very limited environment.

As long as you have one plugin showing the "search options" in one section of the page and another plugin showing only the "results list" in another section, having a common argument namespace gives you exactly what you want.

As soon as you change one of those plugins to use switchable controller actions (usually you make the "results" plugin responsible for both, the "listAction" as well as the "showAction" for detailed information) the whole thing crashes because the "action" argument is a GET argument, too.
So when linking form the listAction to the showAction, not only the "results" plugin gets called to render the showAction. The "search form" receives the very same command (because it listens to the same argument namespace) which results in an exception because of not having switchable controller actions configured properly.

You could have a third plugin for the showAction on a very different page. That definitively works. But you need to be aware of that and create your plugin and page structure accordingly.

That's it!
