GUI: Custom form to access pure plantuml

Duplicate through new controller

See a8b773d , and specificaly grails-app/views/uml/script.gsp

The idea is to have a , and to modify the "src" attribute value when the user clicks on the "Go" button. As the src URL cannot be the full POST data (it may be lots of data), the action should be two fold:

• http POST form data, receive http 201
• set src to 201:location

But that means the server needs to store, even temporarily, the POST data or the image. I don't like this.

http://www.plantuml.com/plantuml/form works this way:

• user clicks on submit
• user is redirected to new page
  • new page has the form filled with the previous UML script
  • new page includes a link containing the GZIPed UML script

I am not fond of:

• page reload
• img URL is compressed form of UML Script (this point is exactly the one I'm trying to circumvent: I want to be able to have arbitrarily long script data)
