    <p>I have a situation where I render items from server in GWT grid on FireFox 3.6+. I have approximately 200 items and I load them in loop:</p> <pre><code>users = myService.getUsers(); for(User user : users){ myPanel.addUser(user); // Pseudocode. Actually i add some labels and text fields... } </code></pre> <p>It tooks a long time to change <code>DOM</code> in this loop, so I got "Unresponsive script" notification. But I can not refactor code or make pagination, I need all 200 items on 1 page loaded at once. </p> <p>Are there any ways to suppress this notification? To notify browser that my script is not hang, but doing something useful?</p> <p><strong>UPD Ok</strong>, here is my code closer. It is a code from big project, and we have many custom components, so, I think, it has no real value.</p> <pre><code> myService.getUsersDetails(searchCriteria, new MyCallback&lt;List&lt;User&gt;&gt;) { @Override protected void response(List&lt;User&gt; result) { gridExpanderPresenter.clear(); int i = 0; for (User user: result) { UserDetailsView detailsView = detailsViewProvider.get(); gridExpanderPresenter.setPresenter(UsersPresenter.this); gridExpanderPresenter.add(detailsView.asWidget()); //Here is DOM manipulation i mentioned if (i++ % 2 == 1) { detailsView.setOdd(); //Setting style here } detailsView.setData(user); } } }); </code></pre> <p>And I think <a href="http://code.google.com/intl/ru/webtoolkit/doc/latest/DevGuideCodingBasicsDelayed.html#incremental" rel="nofollow">this</a> can help me...</p>

    1. COAre you sure that there is no cycling? Don't think that it's a big trouble for PC to proccess 200 items of javascript array... It would be great to look into your code closer, original, not pseudo.

    2. COThat warning should be taken as an indication that your script needs to be revised. You should post the relevant code and perhaps somebody will see potential for improvement.

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).
