Create a Tooltip in Alfresco Process Services Forms

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

This article will show how to use the stencil feature in Alfresco Process Services powered by Activiti to implement a tooltip in forms. I'll be using the Tooltip directives from Angular UI Bootstrap component for this implementation.

1. Download the javascript library from Angular directives for Bootstrap.
2. Copy the downloaded file "ui-bootstrap-tpls-2.5.0.min.js" to your APS web app "activiti-app/libs/ui-bootstrap-tpls-2.5.0/ui-bootstrap-tpls-2.5.0.min.js" 
3. Include this library in "activiti-app/workflow/index.html" as shown below

   <script src="../libs/ui-bootstrap-tpls-2.5.0/ui-bootstrap-tpls-2.5.0.min.js"></script>‍‍‍‍

4. Open the resource loader (activiti-app/scripts/resource-loader.js) file and include this dependency prior to bootstrap as shown below. Line# 10-13 is all I added.

   for (var i = 0, il = res.length; i < il; i++) {
           load(res[i], resourceLoaderElement, function(){
               loadedResources++;
               if (loadedResources == res.length) {
                   // Let angular resume bootstrap
                   var interval = window.setInterval(function(){
                       if (angular && typeof angular.bootstrap == 'function') {
                           angular.element(document.body).ready(function() {
                               // Add custom module dependencies
                               if(angularModuleName == "activitiApp"){
                                   angular.module(angularModuleName).requires.push("ui.bootstrap.tooltip");
                               }
                               // angular, all of our resources & the document body are ready, lets bootstrap the app
                               angular.bootstrap(document.body, [angularModuleName]);
                           });
                           window.clearInterval(interval);
                       }
                   }, 20);
               }
           });
       }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

5. Now we need to update the form-element template to show this tooltip. For example, if you want to show the tooltip on a text field, open the activiti-app/workflow/views/templates/form-element-template.html and add lines 6-9 shown below to the file. For more details on the usage please refer Angular directives for Bootstrap 

   <div ng-switch-when="text" class="form-group {{field.className}}" ng-show="field.isVisible" ng-class="{'has-error': field.required && isEmpty(field)}">
           <label class="control-label">{{field.name}}</label>
           <span class="marker" ng-if="field.required">*</span>
           <input id="{{activitiFieldIdPrefix + field.id}}" type="text" name="{{field.id}}" class="form-control" placeholder="{{field.placeholder}}" ng-model="field.value" ng-change="onFieldValueChange(field)" ng-blur="onFieldBlur(field)" ng-focus="onFieldFocus(field)"
            
                  uib-tooltip="{{field.params.customProperties.tooltip}}"
                  tooltip-placement="'top'"
                  tooltip-trigger="'focus'"
                  tooltip-enable="true"
            
                  ng-required="field.required"
                  ng-minlength="field.minLength || ''"
                  ng-maxlength="field.maxLength || ''"
                  maxlength="{{field.maxLength || ''}}"
                  ng-pattern="field.regexPattern || ''"
                  ng-model-options="{ allowInvalid: true }"
                  masked-input="{{field.params.inputMask}}"
                  masked-input-placeholder="{{field.params.inputMaskPlaceholder}}"
                  masked-input-reversed="{{field.params.inputMaskReversed}}">
       </div>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

6. Now import my example app into APS via App Designer (Kickstart App) -> Apps -> Import App. Once the “App” is successfully imported, the stencil along with an example process and form will also get imported which will make it easy for you to see this examples in action! Given below are some screenshots of stencil, form design time and form runtime. For more details on stencil configuration and form configuration please check the imported stencil and process form.

In APS 1.8, this is broken as the version of angular used (1.3.13) is not compatible with the way ngRoute is invoked. On certain tabs in APS, IDM for example, a browser error around the resource loader is thrown, and an angular description of the error:

Description
This error occurs when a module fails to load due to some exception. The error message above should provide additional context.

Using ngRoute
In AngularJS 1.2.0 and later, ngRoute has been moved to its own module. If you are getting this error after upgrading to 1.2.x or later, be sure that you've installed ngRoute.
