No RequestContext for operation [Solved]
There are already several similar threads but it took me a whole day to solve this, so I hope this extra piece of info may help to somebody else in similar situation. I moved from GWT 2.3 to 2.4. There are no big letters in release readme or anywhere saying that there are breaking changes since RequestFactory validation is totally reworked but after some googling you get the idea. So I quickly ran ValidationTool and created an extra jar and everything was working again. Note that what is may be obvious today could be less obvious a month or two ago as the tool documentation is being constantly corrected. So I went on with my business, refactored half of the interfaces in AppRequestFactory and then boom - a dreaded No RequestContext for operation hit me. First I thought I broke some unspoken extra constraint with RequestFactory or messed up classpath or have wrong web.xml and so on. I updated all my Eclipse plugins, cleaned up everything, removed Maven - no luck. I did rerun ValidationTool but without success. I reverted to a previous version of my code and added a single simple method to an existing AppRequestFactory interface. And got the same No RequestContext for operation. And only at this point I reread that article about new RequestFactory validation, added annotation processor (requestfactory-apt.jar) and voila - everything suddenly works. So if any poor soul out there is in similar shoes may be this story will help a bit. On a side note - GWT documentation is terrible and is getting worse over time. The scope is getting bigger and bigger (Android, App marketplace and so on) but the quality is dropping with each release. A year after RequestFactory release any novice must gather million of pieces about how it works on his own. And the error message is hardly helpful as well (in the same league as the bean is frozen or the streams are crossed). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: SmartGWT migration to 2.4 version
Did you check the release notes to ensure that the version of Smart
GWT that you are using is compatible with the version of GWT that you
are using?
Smart GWT 2.5 lists compatibility from 1.6 to 2.3 of GWT or something
like that...

GWT and Databases
Hi there, I am an absolute beginner with GWT although i am now understanding some concepts. My own project is to, using template when creating a new project in eclipse, connect to an oracle express database, looking for a login within a table and return his name. Technologies seems to have changed between GWT 1.x and GWT 2.x in many ways, and i'm looking for a clear and simple example. Can someone point me in the right direction as i am not able to process examples coming from the internet ? I am now confused between jetty environment xml file to create, use or not GAE, use .launch file, use hibernate, and dozen others things. Understood this is a favor i'm asking, but a sample would be appreciated. Regards, Pierre -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

null pointer exception. I would recommed using the @UiFactory

the provided=true in you @Uifield. It really doesn't matter which

Re: Generics Issue in GWT
Make sure that the path that includes the class GenericService is
included in your GWT xml configuration file.
Just like you include the GWT stuff. See the GWT examples for more
info.
And make sure the source of the class GenericService can be found by
the gwt compiler, that is: it's part of your classpath.

Re: GWT + SVN + Eclipse
If you import the project on the other machine, check your classpath. Most of times it has absolute directory names that are not correct due to the user profile. What I do is stick it in the exact same directory on both computers. This doesn't always work. Another thing I do is unselect GWT in eclipse and apply. This should remove it as a GWT project. Then go back and select it again. This often will reset some of the GWT setup. You can also view the classpath files directly via a text editor and can edit the paths to reflect the correct directory structure. If you get the classpath correct the stuff should work just fine.

The Cell does actually render correctly, selection is broken and you can't

fine.
Is anyone using SafeHtmlTemplates to render a CellTree's leaf nodes ? (Or
can anyone point me to an example of rendering any type of Cell with a

Re: GWT and Databases
See this threadhttp://groups.google.com/group/google-web-toolkit/browse_thread/thread/7e46e8c33e7ee5da. There I share a simple gwt sample that use JPA Spring 2011/10/9 Brandon Donnelson branflake2...@gmail.com Here are some of my MySql JDBC notes here: http://code.google.com/p/gwt-examples/wiki/project_MySQLConn Here is a quick demo - http://gonevertical.org/DemoMySqlConn/ Here is a quick look at JDBC db connection - http://code.google.com/p/gwt-examples/source/browse/trunk/DemoMySqlConn/src/org/gonevertical/demo/server/DB_Conn.java The recommend using JDBC to connect to oracle and the only thing different between the MySql JDBC and Oracle in my example will probably be the query strings and such. I've used several different database connections at one time in a corporate setting and JDBC I've found works great.

Re: No RequestContext for operation [Solved]
I'm sorry if I was too harsh with my statements. I really appreciate GWT and it's a wonderful hack. And it's getting better over time. The complexity of supporting numerous platforms is probably mind-boggling. The amount of trickery used by the framework is far beyond average developer level. So I didn't mean to hurt anyone, just was a little frustrated with the quality of available information. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

No problem at all. I can conquer with those feelings b/c I've done the same thing :) I'm glad you shared, but I can't vouch for others tho.

Re: Using SafeHtmlTemplate to render a Cell in a CellTree doesn't work
Ok this was actually a problem with the template, generating incorrect HTML.
Simplifying the template to a simple div with some text gets everything
work ok.

The Cell does actually render correctly, selection is broken and you can't
close the parent mode, but it indicates the template is working.
If I render the the cell without using a SafeHtmlTemplate everything works
fine.
Is anyone using SafeHtmlTemplates to render a CellTree's leaf nodes ? (Or
can anyone point me to an example of rendering any type of Cell with a
SafeHtmlTemplate? )
My render method looks like:
@Override
public void render(com.google.gwt.cell.client.Cell.Context
context,Foo value, SafeHtmlBuilder sb) {
SafeHtml x = MyTemplate.templateMethod(value.getBar(), value.getY());
sb.append(x);
}

Custom UIBinder Widget, problem expecting only widgets
I am trying to create a custom to use in my UIBinder templates, UL/LI elements are curiously missing.. I used HTMLPanel as a template where I copied the class source to my project. The object itself works fine, but as soon as I try to include HTML code in the element, the UIBinder parser complains saying that my UL widget is only expecting Widgets, but the HTMLPanel can include both HTML and Widgets.. What am I doing wrong ? Thanks -John G -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
