Hello,
Guacamole is a product that I use and love. I recently upgraded
guacamole-client DOCKER versions from 1.3.0 to 1.4.0. This upgrade was largely
due to the requirement of my host server running on RHEL8. I have an extension
that I’ve built for Guacamole and has worked since version 1.10. Now the
extension has regressed.
On Firefox WebTools:
TypeError: $scope.client is undefined
loadScaleBackground https://<hostname>/app.js?b=20240330163951:172
Angular 21
jQuery 8
Angular 15
I have created an AngularJS directive that mocks the client module directive
“app/client/directives/guacClient.js”.
******************** START CODE BLOCK ********************
angular.module('client').directive('myClient', [
function myClient() {
return {
restrict: 'E',
replace: true,
scope: {
client: '=',
},
controller: ['$scope',
'$routeParams',
'ManagedClient',
function guacClientController($scope,
$routeParams,
ManagedClient)
{
// The display and client for the connection
var display = null;
var client = null;
$scope.$watch('client', function attachManagedClient(managedClient)
{
if (!managedClient)
return;
// Get Guacamole client instance
client = managedClient.client;
display = client.getDisplay();
} // end function: attachManagedClient
); // end $watch: client
…
}; // end return statement for chipsClient()
} // end function: chipsClient()
]); // end directive: chipsClient()
******************** END CODE BLOCK ********************
And here is where I inject the HTML directive with extension…
******************** START CODE BLOCK ********************
<meta name="after-children" content=".client-body">
<my-client client="client" menu="menu"></my-client>
******************** END CODE BLOCK ********************
When I inject console.log($scope) into my JS extension, I am returned with the
$scope object with client as undefined.
I suspect that the $scope.$watch(‘client’, … is not returning a newVal of the
client object and passing it to managedClient as undefined. Therefore, it will
hit the return statement every time. I want to say that this is some type of
visibility issue as the webapp “sources” (shown on WebTools) is much different
as it was in guacamole-client v1.3.0. All the client code is no longer put into
app.js and is split into a bunch of files, so maybe this is what’s causing the
issue?
AngularJS is very new to me and I’m learning as I go. Any suggestions are
appreciated.
Thanks,
Eli
