Task refresh-iwidget-definitions

Use this configuration task to refresh iWidget definitions in the portal. This task affects all iWidget definitions that are referenced through absolute HTTP or HTTPS URLs in addition to iWidget definitions that are referenced through WebDAV URIs.

Refreshing an iWidget definition in this context means, reloading the iWidget definition XML files and updating the corresponding iWidget Wrapper portlet clone accordingly. You can run the task in a synchronous or asynchronous manner. If you run this task asynchronously, the configuration task completes immediately after you start a corresponding asynchronous system task. You can use this mode to avoid timeout problems that might occur if there are a high number of iWidget definitions to be refreshed. The completion of the system task is indicated in SystemOut.log.
Notes about this task:
  • refresh-iwidget-definitions updates the titles and the descriptions of an iWidget Wrapper portlet clone only if you set the following portlet preferences to true: com.ibm.portal.replace.titles and com.ibm.portal.replace.descriptions. If these parameters do not exist in the installed iWidget, you must add them and set their values to true.
  • If the lines with the iWidget item id="title" and item id="description" in the iWidget XML file do not include the option readOnly="true" set, the default command does not work. To correct this issue, you can choose between the following options:
    • In the portlet XML file, add the readOnly="true" option to the lines with item id="title" and item id="description" as follows:
      <iw:item id="title" lang="en" value="iWidget Title" readOnly="true">
        ...              
      <iw:item id="description" lang="en" value="iWidget Description" readOnly="true">
    • When you run the ConfigEngine task, include the option -DForceRefresh=true option as follows:
      ./ConfigEngine.sh refresh-iwidget-definitions 
                        -DIWidgetDefinition=/iWidget/iWidget.xml 
                        -DForceRefresh=true
    • Add the following portlet parameter to the installed iWidget: com.ibm.portal.replace.attributes = true.
  • When you refresh an iWidget Wrapper portlet clone, values of iWidget attributes, or the items of the iWidget attributes item set, are not updated. The values are updated if the attributes are flagged as read-only in the iWidget definition XML file. As a result, values of iWidget attributes that are customized after you register the iWidget in HCL Portal are prevented from becoming lost during a refresh operation.
Usage: Use this task to refresh iWidget definitions in the portal.
Important: HCL Portal must be running to use this task.
