    <p>You are setting 100% height of the <code>VerticalPanel</code> in the middle of the <code>DockLayout</code>, but you are not setting also the middle cell height to 100%. Try with:</p> <pre><code>dockPanel.setCellHeight(mainPanel, "100%"); </code></pre> <p>Anyway using tables and percentages can lead to subtle problems that often you need to handle on your own. Always ask yourself "100% of what?".</p> <p>Also, quoting the javadoc from <code>DockPanel</code>:</p> <blockquote> <p>This widget has limitations in standards mode that did not exist in quirks mode. The child Widgets contained within a DockPanel cannot be sized using percentages. Setting a child widget's height to 100% will NOT cause the child to fill the available height.</p> <p>If you need to work around these limitations, use DockLayoutPanel instead, but understand that it is not a drop in replacement for this class. It requires standards mode, and is most easily used under a RootLayoutPanel (as opposed to a RootPanel). </p> </blockquote> <p>Using <code>&lt;!DOCTYPE html&gt;</code> sets the page in standard mode, meaning this will not going to work properly, and in quirks mode you have to experiment on your own.</p> <p>Try also to consider using a <code>Layout</code>-based approach, as suggested by the javadoc. Since you are using a single div for the whole page (that <code>rootContainer</code>), it should be painless to use.

    1. COThanks for your reply. When i use the DockLayoutPanel along with the RootLayoutPanel, then I have the problem, that there is no scroll bar for the whole page. Note that the center has a fixed size. Is it bad coding, if I set the size of the center cell when the window was re-sized? Or is there a better solution for having a fixed footer/header size and the center has a minimum size, but should fill the rest?

    2. COYes, `RootLayoutPanel` means taking the whole page and keep track of browser resizing events and provide them accordingly down to the DOM, hence no scrollbar at all. I generally avoid to mix and match table-based widget, try to replace `VerticalPanel`s with simpler `FlowPanel`s and a bit of CSS. Sorry for not being more precise but I can't even reproduce the problem.

    3. COEven if i remove the `VerticalPanel` an just add a `Composite` which holds an `AbsolutePanel` the height of the center component is not correct. I'm wondering because the the description of the `DockPanel`is saying: "A panel that lays its child widgets out "docked" at its outer edges, and **allows its last widget to take up the remaining space in its center**. "

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.
