    <p>Another way to go (cheap if you are coding right now, expensive if you've already coded everything) would be to modularize every action you have to perform in one single Struts2 Action.</p> <p>Then you will have something like an <code>BaseReportAction</code>, containing all the common attributes and methods shared using <code>protected</code> instead of <code>private</code>, doing your tuning on parameters and the common operations in the <code>execute()</code> method; </p> <p>And one Action for each report extending the BaseReportAction, let's say</p> <blockquote> <p>ExcelReportAction, PdfReportAction, etc...</p> </blockquote> <p>or </p> <blockquote> <p>MinimalReportAction, CompleteReportAction, etc...</p> </blockquote> <p>or also </p> <blockquote> <p>DailyReportAction, MonthlyReportAction, etc...</p> </blockquote> <p>And the only requirement would be using <code>super.execute();</code> as first statement of every child Action's <code>execute()</code> method.</p> <p>This way you could take advantage of the inheritance, to have a lot of smaller, cleaner (eventually packaged into several sub-packages) Actions instead of one huge Action with a lots of methods.</p> <p>All the utility methods used by few reports would be available only for those reports, not for all the others (let's say PDF and XLS stuff for example)...</p> <p>You could benefit of the XML Validation too for different Actions (maybe one report requires different inputs from another).</p> <p>Finally, your tuning-up code would be Thread-Safe (Actions are Thread-Safe, Interceptors don't).</p> <p>But as said, this is a choice of implementation that better suits the pre-code phase (even if it's not that hard to refactor, according to the size of the web application...).</p>

    1. COi think i can do the same calling `tuneParameters()` instead of `super.xxx`. but that still violates DRY

    2. COYou can do that but it's not the same. Let's say tomorrow you wanna call ten different methods in `execute()`, then you would have to add 9 rows into every `execute()` method of every Action. Let's say you change the name of the `tuneParameters()` method, you will have to change it into all the other actions, etc. With super, you write it once and you forget it. The only possible error would be you forget to write it the first time, quickly detectable and fixable... however the real point is in the other benefits listed (and this is one way to go, not the only one :)

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
