I’ve created a plugin from wizard “Plugin with a mutli tab Editor”.

Problem: In Project Configuration if I set the File Extension field to html, the plugin not works. If I leave it mpe (pre-inserted field) or I insert another unknown file extension, then it works.

What can cause this problem and how can I activate the plugin for html files?

EDIT:
Ok, I’ll try to describe step by step my problem.

I create a new Plugin Project
new plugin project

I set project name:

project base settings

…and the project properties

project properties

I create a plugin using template “multi page editor”

templates plugin

Now, I must choose the class names and File Extension (mpe is pre-inserted from eclipse, I leave it for now).

enter image description here

Ok. Eclipse generate all files and a project that works. So, if I test it:

run eclipse

and I create a test project with a test.mpe files

test project

I can see 3 tabs (because 3 tabs are configured in template code) and a default icon on file name test.mpe on Project Explorer. The plugin WORKS!

Now… I close all and I repeat EXACTLY all steps, I using HTML instead of MPE, I test it and… there is no tabs and there is no icon.

test html

Why? And How can I solve it?

    Your editor is not set as the default, and the one you have installed is being chosen instead. See the full documentation and example at http://help.eclipse.org/juno/topic/org.eclipse.platform.doc.isv/reference/extension-points/org_eclipse_ui_editors.html?cp=2_1_1_143 .
