Problems using the org.eclipse.wst.xml.ui.StructuredTextEditorXML [message #60136]

Hi everybody,

I am just trying to integrate the wst XML Editor into my project, but I
have some struggling problems.

As lamer solution I just added the class
org.eclipse.wst.xml.ui.StructuredTextEditorXML as contributor class to
the plugins.xml file of my plugin.

Normally this works (tried it with my other plugins), but the
org.eclipse.wst.xml.ui.StructuredTextEditorXML only displays a modal
error message box: "Problems opening Editor - Editor could not be
initialized".

Is this issue known to you? And how do I get clearer debug information
(on the console is nothing - and as well no errors).

Thanks a lot!
...and a happy new year,

Raphael

my tiny test plugins.xml:

<requires>
<import plugin="org.eclipse.ui"/>
<import plugin="org.eclipse.core.runtime"/>
<import plugin="org.eclipse.jface.text"/>
<import plugin="org.eclipse.ui.editors"/>
<import plugin="org.eclipse.ui.workbench.texteditor"/>
<import plugin="org.eclipse.wst.xml.ui"/>
</requires>

<extension
point="org.eclipse.ui.editors">
<editor
name="Sample XML Editor"
extensions="grenouille"
icon="icons/sample.gif"

contributorClass="org.eclipse.ui.texteditor.BasicTextEditorActionContributor "
class="ra.scs.texteditor_test.editors.XMLEditor"
id="ra.scs.texteditor_test.editors.XMLEditor">
</editor>

<editor
name="TestName"
icon="icons/sample.gif"
extensions="g_t"

contributorClass="org.eclipse.wst.xml.ui.actions.ActionContributorXML "
class="org.eclipse.wst.xml.ui.StructuredTextEditorXML"
id="org.eclipse.wst.xml.ui.StructuredTextEditorXML2">
</editor>

I've opened an enhancement request against the base, long long ago, to not swallow those exceptions,
see (and vote on?) https://bugs.eclipse.org/bugs/show_bug.cgi?id=52081

I've found it useful to set up the debugger to stop on CoreException in such cases and usually can help provide a starting point ... to know where else to set breakpoints, etc.

(Sorry, not sure what the underlying problem might be, off the top of my head).

Raphael,
The first thing to check is if your test files open with the XML
Source Page Editor. The SSE editors require the SSE IDocument
implementation and throw assertion failures if that's not what
they're given for an input. This is one of the big causes for bugs
78340 and 81710.

If it really is XML and just an unrecognized filename extension, you
can try teaching Eclipse that it is XML with this _as a workaround_:

<extension
point="org.eclipse.core.runtime.contentTypes">
<file-association
content-type="org.eclipse.core.runtime.xml"
file-extensions="g_t,grenouille,xmlfoo2"/>
</extension>

thanks Nitin, I just tried your workaround and it works perfectly.
Hmm. Although I do not realise what the problem really is.

What I do not understand is, when I use the basic XML Editor delivered
in eclipse as an example (titled Plug-In with an editor) it works fine
with just a "reference" to this editor in the plugins.xml of my other
plugin. But when I use the same mechanism with the
StructuredTextEdtiorXML it does not work (error I described above). With
your workaround it works... I do not get the point.

But many thanks for all replies - good to have a helping community...!

I've tracked the problem down, updated the bug report and moved it to
the right component.

The symptom really is that the SSE editors *require* the SSE
IDocument implementation and that that implementation is not the
default for your filename extensions. SSE makes it's implementation
the default for common XML file extensions that we know about in
advance, but for unknown extensions like g_t and grenouille the
default remains the Eclipse platform's default.

Keep an eye on bug 78340,
