    <p>I need to get the component associated to a Activity at the event system.</p> <p>I try to get the component ID using:</p> <pre><code> public void OnActivityInstanceFinishPost(ActivityInstance activityInstance, string finishMessage, string nextActivity, string dynamicAssignee) { if (activityInstance.ProcessInstance.ProcessDefinition.Title.Equals("Component Process IESE")) { if (activityInstance.ActivityDefinition.Title.Equals("Create or Edit Component")) { WFE workflow = tdse.GetWFE(); try { Component comp = (Component)activityInstance.ProcessInstance.Item; XMLReadFilter filter = new XMLReadFilter(); String processHistoryId = activityInstance.ProcessInstance.ID.Replace("131076", "131080"); ProcessHistory hist = (ProcessHistory)tdse.GetObject(activityInstance.ProcessInstance.ID, EnumOpenMode.OpenModeView, Constants.URINULL, filter); } catch (Exception e) { } } } } </code></pre> <p>we try different options:</p> <pre><code> Component comp = (Component)activityInstance.ProcessInstance.Item; </code></pre> <p>But this solution returns a null.</p> <p>Then I found in internet the next solution:</p> <pre><code> XMLReadFilter filter = new XMLReadFilter(); String processHistoryId = activityInstance.ProcessInstance.ID.Replace("131076", "131080"); ProcessHistory hist = (ProcessHistory)tdse.GetObject(activityInstance.ProcessInstance.ID, EnumOpenMode.OpenModeView, Constants.URINULL, filter); Component comp = hist.Item as Component; </code></pre> <p>But the ProcessHistory object is null.</p> <p>How can I determine the component associated to the activityInstance?</p> <p>Thank you.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
