<hr> UPDATE #2: The boys down at SpringRoo passed the buck over to the boys over at Google. See the ticket <a href="http://code.google.com/p/google-web-toolkit/issues/detail?id=5351" rel="nofollow">here</a>. It was upgraded to critical priority as well. <hr> UPDATE: I've logged a bug on the SpringRoo Issue Tracker. It looks like the boys are taking this seriously. They've upgraded the priority from minor to critical. See the issue <a href="https://jira.springsource.org/browse/ROO-1482?page=com.atlassian.jira.plugin.system.issuetabpanels%3aall-tabpanel" rel="nofollow">here</a>. <hr> Hi everyone, I was able to get GWT to work with SpringRoo following the mini-tutorial on the SpringRoo page here: <a href="http://www.springsource.org/roo/start" rel="nofollow">http://www.springsource.org/roo/start</a> I then decided to try their other tutorial here: <a href="http://static.springsource.org/spring-roo/reference/html/beginning.html" rel="nofollow">http://static.springsource.org/spring-roo/reference/html/beginning.html</a> After completing Step 6, I decided to try it out with GWT. I thought it would be as simple as running the <code>gwt setup</code> command from the Roo shell, but it wasn't. When I ran the project, I noticed that the command would create files (as expected), then start undoing the files it created, and finally end off with an exception: <code>String index out of range: -1</code>. Not knowing much about Roo and GWT, I ran the <code>mvn gwt:run</code> command anyway, just to see if it might work. Well, to no surprise, it didn't. I found the following JIRA issue for the <code>mvn gwt:run</code> command, but it didn't work. I'm sure it won't work until the first issue is resolved <a href="http://jira.codehaus.org/browse/MGWT-57" rel="nofollow">http://jira.codehaus.org/browse/MGWT-57</a> ADDITION: MGWT-57 says to try mvn clean gwt:run. I did and tried running mvn gwt:run afterward to no avail -- same error message. MGWT-57 also says to move some nodes around though I must admit I have no clue what nodes they are referring to. I did, however, search for <code>gwt-maven-plugin</code> as well as the node <code>runTarget</code> as they were in the error message, but they were no where to be found in my pom.xml. I thought that to be strange, and deduced it's probably because of the first issue when running <code>gwt setup</code>. I'm having a hard time finding anything for the first issue, running the <code>gwt setup</code> command in the Roo shell, which is why I'm here. Any ideas? I have included the output from the two commands below. Thanks for the help in advance! Output of the <code>gwt setup</code> command: <pre><code>Managed ROOT/pom.xml Managed ROOT/pom.xml [Added dependency com.google.gwt:gwt-servlet:2.1-SNAPSHOT] Managed ROOT/pom.xml [Added dependency com.google.gwt:gwt-user:2.1-SNAPSHOT] Managed ROOT/pom.xml [Added dependency org.json:json:20090211] Managed ROOT/pom.xml Managed SRC_MAIN_WEBAPP/WEB-INF/web.xml Managed SRC_MAIN_WEBAPP/WEB-INF/spring/webmvc-config.xml Created SRC_MAIN_JAVA/com/springsource/roo/pizzashop/gwt Created SRC_MAIN_JAVA/com/springsource/roo/pizzashop/gwt/ApplicationScaffold.gwt.xml Created SRC_MAIN_JAVA/com/springsource/roo/pizzashop/gwt/ApplicationCommon.gwt.xml Created SRC_MAIN_JAVA/com/springsource/roo/pizzashop/gwt/ApplicationMobileScaffold.gwt.xml ...

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.
