Web UI won't load overriden elements in chrome

Hello everyone,

I have come to notice that the web UI won't load the overriden elements in chrome if the network speed is slow. I tried changing the network speed from the dev tools to Fast 3G or slower. The interface will load only the default elements and leave aside any custom elements.

I modified the document actions slots for the edit and delete document buttons with custom logic, this slots where added to a html file called my-custom-bundle.html:

<nuxeo-slot-content name="deleteDocumentAction" slot="DOCUMENT_ACTIONS" order="15">
        <my-delete-document-button document="[[document]]"></my-delete-document-button>

<nuxeo-slot-content name="deleteSelectionAction" slot="RESULTS_SELECTION_ACTIONS" order="30">
        <my-delete-documents-button documents="[[selectedItems]]"></my-delete-documents-button>

I can see my components being loaded in the network tab, but if I examine the buttons from the ui they are just the default ones.

Could this be a problem with my deployment fragment, or the require tag order?

I share my deployment-fragment changes:

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

<fragment version="1">
    <extension target="application#MODULE">
        <!-- unzip the war template -->
        <unzip from="${bundle.fileName}" to="/" prefix="web">
        <!-- create a temporary folder -->
        <delete path="${bundle.fileName}.tmp" />-
        <mkdir path="${bundle.fileName}.tmp" />
        <unzip from="${bundle.fileName}" to="${bundle.fileName}.tmp"/>

        <copy from="${bundle.fileName}.tmp/web/nuxeo.war" to="/"/>
        <!-- append the translations -->
        <append from="${bundle.fileName}.tmp/web/nuxeo.war/ui/i18n/messages.json" to="nuxeo.war/ui/i18n/messages.json" addNewLine="true"/>
        <delete path="${bundle.fileName}.tmp"/>

This is the component I declared to add the custom ui elements to the bundle:

<?xml version="1.0"?>
<component name="studio.extensions.remove-button" version="1.0.0">
    <extension target="org.nuxeo.ecm.platform.WebResources" point="resources">
        <resource name="delete-document" type="import" shrinkable="false">
        <resource name="delete-documents" type="import" shrinkable="false">
    <extension target="org.nuxeo.ecm.platform.WebResources" point="bundles">
        <bundle name="web-ui">
            <resources append="true">

Finally, this is my manifest file to include my contribution:

Bundle-ActivationPolicy: lazy
Bundle-ClassPath: .
Manifest-Version: 1.0
Bundle-Vendor: my.bundle.vendor
Bundle-Version: 1.0.0
Bundle-Name: ssa-tree
Bundle-ManifestVersion: 2
Require-Bundle: org.nuxeo.runtime
Bundle-SymbolicName: my.custom.bundle;singleton=true
Nuxeo-Component: OSGI-INF/extensions.xml,
Import-Package: org.nuxeo.ecm.core,

Is there any other configuration missing or wrong?


After some research, I found a jira ticket https://jira.nuxeo.com/browse/ELEMENTS-1096 in which it explains it's most likely a bug with the chrome browser. Tested with firefox, even reducing network speed at maximum everything loads correctly unlike with chrome.

Hopefully some fix will be released soon

Hello again,

I have being rethinking about this issue, and after some tests I think I came up with a solution. Instead of overwriting the buttons, why don't you create a new one and then hide the default ones? For example, with the delete button:

<!-- Add your custom button -->
<nuxeo-slot-content name="myCustomdeleteDocumentAction" slot="DOCUMENT_ACTIONS" order="15">
        <my-delete-document-button document="[[document]]"></my-delete-document-button>

<!-- Disable the default delete button -->
<nuxeo-slot-content name="deleteDocumentAction" slot="DOCUMENT_ACTIONS" disabled></nuxeo-slot-content>

I have tested this solution, and it worked pretty good. I also added a new more generic “require” tag in the bundle. This requirement is added when you generate the custom elements using Nuxeo Studio:

<?xml version="1.0"?>
<component name="studio.extensions.remove-button" version="1.0.0">

And finally, I have also seen you didn't import the custom elements in “my-custom-bundle.html”. I think you forgot to add them only in this topic, but just in case, remember to add them:

<link rel="import" href="path/to/my-delete-document-button.html">  
<link rel="import" href="path/to/my-delete-documents-button.html">  

I hope this solution will help you.

Thank you very much for your insight and suggested solution Rodri, this might work, I will try it out!

I hope my solution worked as a temporary solution. However, I think this problem has been recenty solved with the new HotFix HF20: https://connect.nuxeo.com/nuxeo/site/marketplace/package/nuxeo-10.10-HF20 . The first correction is "Overriding a slot content has a consistent behavior in Chrome.". Regards.
