e4 Compatibility Layer

[Daniel Zimmermann]

Hi everyone,

I don't get it: Every now and then, when I try to let my "old" 3.7 bases Application run within the compatibility layer of 4.2 I run into the same kind of Problems.

Simetimes I get them solved, sometimes (as today) I don't.

What I get:

java.lang.NoClassDefFoundError: org/eclipse/ui/plugin/AbstractUIPlugin

Where? On loading org.eclipse.ui.forms (BundleActivator):

Caused by: org.osgi.framework.BundleException: The activator org.eclipse.ui.internal.forms.FormsPlugin for bundle org.eclipse.ui.forms is invalid

As far as I know, my dependecies are ok:

Naturally I've already added plugins neseccary for the compatibility part to my launch configuration, but still to no avail...

Do I miss something???

Hi Daniel,

the product is leading, make sure you have all dependencies here maintained. You can use "Check Dependencies" to verify that. 

Best regards, Lars

I tried to avoid that, since I had some trouble with this option in the past (2 years ago or so :-) ).

Even so, I did it and there was at least a little more success to it, since my custom Worskapce selection dialog opened. But in the further process (on selecting a workspace) it crashed immediatelly.

Damit! But I will go on!

Hi,

the program is now up and running:

Beside to add the plugins I forgot (again) to press the "add required plugins" button within the product editor :-/

But there is something else odd now:

The toolbar icons from my ApplicationActionBarAdvisor are at the place, where the perspective bar would be, if I would have it activated (if I activate the perspective bar, the toolbar icons are still on the right side of it).

The other annoying thin is the "Nameless Window" - as you can see, the Title Area of the Window is empty resulting in a "Nameless Window" on my Unity top panel, when focused.

I tried to use my own version of a LegacyIDE.e4xmi, but it seams, it's never checked from within my plugin.xml

   <extension

         id="product"

         point="org.eclipse.core.runtime.products">

      <product

            application="com.mycompany.p2p.tracker.rcp.pfs.ssdtool.application"

            name="PFS Customer Platform">

         <property

               name="windowImages"

               value="icons/ipqlogo_16.gif,icons/ipqlogo_32.gif,icons/ipqlogo_64.gif,icons/ipqlogo_128.gif">

         </property>

         <property

               name="appName"

               value="PFS Customer Platform">

         </property>

         [...]

         <property

               name="applicationXMI"

               value="com.mycompany.p2p.tracker.rcp.pfs.ssdtool/LegacyIDE.e4xmi"><!-- <plugin-id>/<e4xmi-file> -->

         </property>

         <property

               name="cssTheme"

               value="org.eclipse.e4.ui.css.theme.e4_default">

         </property>

      </product>

   </extension>

and yes, I gave the TrimmedWindow a label:

 

I don't understand, why my settings seem to be ignored during the application startup.
