    <p>Suppose, there is an event observer class in core. I can override it. But, is it safe? I mean, does it affect other functions of the observer class? </p> <p>Like, if there are two functions in core observer class and I did override only one function. Then, will the other function work safely as before.</p> <p>I think it is similar to model override and should be safe. Am I right?</p> <p><strong>Edit</strong>:-</p> <p>For example,</p> <ul> <li>There is a class <strong>CoreClassA</strong> in core.</li> <li>There is a function <strong>coreFunctionA</strong> in <strong>CoreClassA</strong>.</li> <li>An event <strong>core_event_a</strong> is dispatched in this <strong>coreFunctionA</strong>.</li> <li>Another core module <strong>CoreModuleB</strong> is creating event observer with <strong>core_event_a</strong>. </li> <li>So, whenever <strong>core_event_a</strong> is dispatched, <strong>CoreModuleB</strong>'s event observer is called.</li> <li>Suppose, <strong>CoreModuleB</strong>'s event observer contains two functions. One for <strong>core_event_a</strong> dispatch action (let us name it <strong>eventDispatchA</strong>) and another for some other event dispatch action (let's say <strong>eventDispatchX</strong>).</li> <li>In my custom module, I want to override <strong>eventDispatchA</strong>. <em>Basically, I want to change the some code in eventDispatchA or, I may just want to skip/omit this function</em>. I can override it. <em>But, will it affect <strong>eventDispatchX</strong> if I do so? Or, is there any other better way instead of overriding event observer?</em></li> </ul>

    1. COcan you tell us why you want to override the class? There might be a better way to achieve the same effect

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.
