Plugins in Cockpit 7.5-alpha

Camunda 7 Topics Discussion & Questions

Hey guys.

I encounter problems with existing plugins which worked fine on 7.4.x but cause errors on 7.5 (alpha1 or alpha2).

E.g. this line here: https://github.com/camunda/camunda-consulting/blob/master/snippets/cockpit-plugin-reporting/src/main/resources/plugin-webapp/reporting-process-count/app/plugin.js#L167:
$('#lineChart').highcharts({

causes a JavaScript error:

ReferenceError: $ is not defined
    at printStartedInstances (plugin.js:167)
    at plugin.js:10
    at camunda-cockpit-ui.js:2
    at k (camunda-cockpit-ui.js:2)
    at k (camunda-cockpit-ui.js:2)
    at camunda-cockpit-ui.js:2
    at k.$eval (camunda-cockpit-ui.js:3)
    at k.$digest (camunda-cockpit-ui.js:3)
    at k.$apply (camunda-cockpit-ui.js:3)
    at i (camunda-cockpit-ui.js:2)

Any ideas?

Cheers
Bernd

Yep, very likely due to the change from requirejs to browserify, $ a.k.a. jQuery is not available on the window object.
If you replace $('#lineChart') by jQuery('#lineChart') it should work again.

Cheers!

Hi Vale.

Will this be mentioned in the release notes (and is it unavoidable)? I think this might break a lot of plugins.

Cheers

PS: With this change - does it still work on < 7.5?

If you do the replacement from $ to jQuery, it should still work (I had a quick check in a previous distro).

I believe it should be mentionned we could easily fix that by adding something like that

window.$ = jQuery;
// or
window.$ = jQuery.noConflict();

but it should be discussed a bit further I think

We didn’t implicitly added the $ (jQuery) variable to the window object… it is, historically (good’ol times), the way jQuery bound itself…

maybe this would help you to make it 7.5 and 7.4 compatible?

if(!window.$)
{
    if(jquery)
    {
        window.$ = jquery;
    }
    else
    {
        alert("no jquery!");
    }
 }

or the other way around :slight_smile: always use jquery(...) and put window.jquery on it if not defined …
