Is it possible to edit an EMF model with two different editors? [message #384137] Mon, 26 April 2004 13:31 Go to next message

I have a need to present two different looks when using an EMF based editor.
Initially I wanted to move a child that had children of it's own into the
properties view. I wanted this because the typical user would never drill
further than 6 levels of an 8 level tree. To reduce confusion I followed
the advice in Chapter 14 to supress display of elements below level
6(OperationalElement). However this forum had several posts that suggested
this may not be possible, or at least non-trivial.

I then thought that I could have two editors, the default and an admin
editor. This proved problematic since I can only get one editor to work
with a given file extension.

Any suggestions would be appreciated:

Thanks,

Charlie

P.S.
The editor is generated from W3C Schema and looks like:

<?xml version="1.0" encoding="UTF-8"?>

Charles,

Not showing children past a certain level should be easy. What's the problem
with doing that? It's also possible to have multiple editors for the same
extension; you just need to do "Open With" to choose....

Thanks for the quick reply Ed!

Not showing children was indeed easy, the difficulty for me was still being
able to edit the children as nested elements in the properties window.
Since I could have two datasources beneath an operational element, only the
first one would show, and since each datasource can have it's own parameter
children(a name/value pair) I was unsure how to get the nested children to
appear and after reading
http://dev.eclipse.org/newslists/news.eclipse.tools.emf/msg0 3243.html I
decided to try using multiple editors.

As you stated "Open With" allows me to open with the editor of choice,
however there seems to be some conflict between the editors, since they both
work individually (loaded into plugin registry in runtime workspace) however
when both plugins are loaded into the runtime workspace I get the display
shown in the attached gif.

I wonder if the conflict is due to the manifest files?

Editor 1:
<extension point="org.eclipse.emf.ecore.extension_parser">

<parser

type="forceorganization" <!-- was forceorganizationadmin based on name of
xsd used to generate editor -->

class="forceOrganization.util.ForceOrganizationResourceFactoryImpl " />

</extension>



Editor 2:

<extension point="org.eclipse.emf.ecore.extension_parser">

<parser

type="forceorganization"

class=" forceOrganizationAdmin.util.ForceOrganizationAdminResourceFa ctoryImpl
" />

</extension>

Charles,

You cannot globally register two different parsers for the same extension. Have
a look at the Ecore editor plugin.xml and the classes in that plugin to see how
a single editor can be reused to behave like multiple different editors.
