"Find All references" is always disabled

[apupier]

Description

The "Find All references" action on right-click is greyed out on Camel files although it should be available.

it should even provides results when right-clicking on the "direct:name1" Find all references

it is working fine in VS Code:

Reproduction Steps

• install Camel VS Code extension in Che

"attributes": {
    "editor": "org.eclipse.che.editor.theia:1.0.0",
    "plugins": "che-machine-exec-plugin:0.0.1,https://raw.githubusercontent.com/apupier/che-plugin-registry/109-AddApacheCamelVSCodeExtension/plugins/camel-tooling.vscode-apache-camel:0.0.14"
  }

• create a camel.xml file

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd        http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">
    <camelContext id="cbr-example-context" xmlns="http://camel.apache.org/schema/spring">
        <route id="cbr-route">
            <from id="_from1" uri="timer:timerName?delay=1000"/>
            <to id="_to3" uri="direct:name1"/>
        </route>
         <route id="cbr-route">
            <from id="_from1" uri="direct:name1"/>
            <to id="_to3" uri="file:work/cbr/output/others"/>
        </route>
    </camelContext>
</beans>

• right-click on "direct:name1"

Does "find all references" work for other plugins?

[apupier]

Does "find all references" work for other plugins?

that is a good question.
I know only the java plugin which is providing "Find all references" feature but I'm unable to install it on che.openshift.io today

[apupier]

I was able to install Python Language Server. it is not working neither with it. So looks alike a generic issue with "find references"

not working in Che

finally able to install Java. And there is also the same problem:

I tested with Camel example and it is working fine in Theia.

[tsmaeder]

@apupier so are you saying this is fixed?

[apupier]

@apupier so are you saying this is fixed?

no.
it is working in Theia standalone but not in Theia inside Che.

Tested on minishift, workspace attributes:

 "attributes": {
    "editor": "org.eclipse.che.editor.theia:next",
    "plugins": "che-machine-exec-plugin:0.0.1,https://raw.githubusercontent.com/eclipse/che-plugin-registry/master/plugins/camel-tooling.vscode-apache-camel:0.0.14",
    "persistVolumes": "false"
  },

[apupier]

tried again, it is working with org.eclipse.che.editor.theia:next and not working with org.eclipse.che.editor.theia:1.0.0 which is the one selected by default.

[tolusha]

1.0.0 probably outdated version and findAllReferences weren't implemented there.
Can we close the issue?

[apupier]

Can we close the issue?

I think it depends on the methodology used in Che.

suggestion:

• check that there is an automated test for this feature
  • if no, it would be better to write it before closing (or at least create a specific task for it before closing)
  • if yes, can be closed.

[tolusha]

What do you mean by "automated test" ?

[apupier]

What do you mean by "automated test" ?

I mean a test which is executed on a Continuous Integration server on each build/Pull Request of Che or one of its components.

[tolusha]

We have api tests eclipse-theia/theia#4224
If we are talking about e2e test then it is question for QE team.
There is nothing we can do here.

[apupier]

if there is unit test, we are in the case "if yes, can be closed" :-)
