Hi all,
SFTB . I have a scenrio as follows:-
1) The pie chart has to be updated every 30 seconds.
2) The data for the pie chart is to be fetched by HTTP.
I am able to receive the data through HTTP and parse it. However I am not
able to update the data of the pie chart every 30 seconds.
I am using visualization charts for this.
Can anyone provide me similar code snippet too?
Any help appreciated

Does str < "test" not get the result you want?

Yes, but that was not the question. I'd like to be able to invoke methods
from the Java String implementation. The code above is meant just as an
example for the error I get.

The format object.@Class::method(param;)(arg) you are using seems fine
(I use it in multiple places). Are you sure the error is not in the
call to your "test" method? Has it been properly exported?

I tried upgrading from 2.5.0 to 2.5.1 but I am getting an error during the
gwt compile. I googled that I needed to remove my gwt-junitCache, which I
tried but it doesn't seem to be helping. I am still using the 2.5.0 gwt
maven plugin since the 2.5.1 is not available. Could that be causing the
problem? Thanks.

Deleting gwt-unitCache solved the issue for me. I have also deleted
war/<appname> and war/WEB-INF/deploy but I think thats not needed.
Can you compile through Eclipse using GPE? I don't think the maven plugin
itself is causing the problem. Maybe you still have a gwt-unitCache folder
lying around somewhere that you haven't found/deleted yet?

Hi,
I just tried serializing data using ListDataProvider.getData();
Which returned a RPC exception, because this would return a ListWrapper
implements List<T>.
And as the gwt ListWrapper does not implement Serializable itselft, this
fails.
Thus, what is best extracting the data to a serializable list? Create a new
ArrayList > addAll() > and then serialize?
List<Foo> serializeList = new
ArrayList<Foo>().addAll(listDataProvider.getData());
Could I do better?
Jens <jens.nehlmeier@gmail.com> Feb 15 09:35AM -0800
> Could I do better?
I don't think so. Well, you could always write your own ListDataProvider
and/or file an issue in the meantime.

Hi,
I have a problem installing the GPE. I hope I am not wrong here but I dare
to ask this question here now after a long search without any results for
me..
I was running Eclipse Indigo with the GPE installed and everything worked
fine. Now I tried to use Juno and of course install the GPE. The
installation finished completely without any errors.
The problem is that now the "Google Web Toolkit" context menu in the
Project Explorer is gone! The Google-Icon in the toolbar is present
though..
The pictures show my misery. The projects are the default GWT-projects
created with the new Web Application wizard. On the first picture the menu
is gone and the second picture shows how it usually has been and how I
would like to see it again...
Even if I install it with Indigo again the menu is gone.. I don't know what
to do.
Does anybody have an idea if this could be fixed by some configuration or
how else I could get this menu back?
Thanks!
Jens <jens.nehlmeier@gmail.com> Feb 15 09:24AM -0800
I think you have forgot to install GWT Designer or it has failed to install
in Juno.
GPE does not provide the context menu. At least I never had one in all my
Eclipse versions and I have always only installed GPE and never GWT
Designer. So I guess its provided by GWT Designer.

Hi,
how can I have different odd/even rows for a CellTable, and prevent
background changes on any selections (mouse or keyboard)?
.cellTableEvenRow, .cellTableEvenRowCell: white
.cellTableOddRow, .cellTableOddRowCell: red
When enabling keyboard selection, I want the color to NOT change, only the
border.
.cellTableKeyboardSelectedRowCell {
border: selectionBorderWidth solid inherit;
}
.cellTableSelectedRow { <--I assume this is the important one?
background: inherit;
color: inherit;
}
.cellTableSelectedRowCell {
border: selectionBorderWidth solid inherit;
}
Result: The red odd rows get white background on selection. Why? How can I
prevent this?

I'm having the exact same problem.
I went further and downloaded the source, but its not documented at all and
seems to reference several classes underneath com.sun.* packages which are
not available to modern JDKs.

The most easy workaround is probably to download the
CometSerializerGenerator.java from the issue you have mentioned and put it
into your app's project into the correct package.
Then as long as your classes/output folder is before gwt-comet.jar in your
classpath the GWT compiler should pick up the generator from your app's
project instead of gwt-comet.jar.
Alternative is to rebuild gwt-comet from source and replace the file
beforehand.

Hi,
I have a CellTable with Columns represented by EditTextCell.
Now, if I'm not in edit mode but hit a certain key while an entry is just
selected, I want to perform a specific action. Like deleting the whole row
on DEL key.
Problem is: I can catch the event if I extend EditTextCell and override
onBrowserEvent, then checking the event.getKeyCode().
But what can I do thereafter to modify the list of the CellTable where the EditTextCell
is inside?
class CellTableWrapper {
private CellTable<Foo>;
private ListDataProvider<Foo>;
}
class ExtendedTextCell extends EditTextCell {
@Override
onBrowserEvent(..) {
//how to modify listdataprovider on certain events??
}
}

Not claiming to be an expert here, but from my experience GWT consulting is
probably not viable. This would depend on if you have contacts/inroads into
companies already using GWT. You'd probably just be better off going with
plain Java consulting which is an enormous market, and it really comes down
to the same thing: writing Java code.
Alternatively, you can develop some B2B systems in GWT, and then sell
customized solutions of it to companies. Customizing a B2B GWT app would
probably be the 1 week to 3 months timeframe. Support for businesses may be
more difficult as a 1 man shop though, but it depends on the webapp.
Definitely should be more fun and personally stimulating than trudging away
on some companies monster GWT business app all your life though!

I learned GWT back at 1.2 or so to more easily put a web front end on my
server side code. I have fairly wide and deep experience in server-side
and cloud technologies, but it's the GWT on my resume that keeps recruiters
calling week after week, year after year. I've taken several GWT jobs,
including two work-from-home jobs lasting a couple years. I've had to make
an actual effort to steer towards server-side programming for a change. It
seems like a strong market for a one-man operation to me.
Good Luck,
Glenn

Well, thanks for the response first of all.
What I have in module xml file is this line:
<add-linker name="xs" />
but even after I removed it and recompile the project I am still getting
md5.cache.js files instead of cache.html files.

Hi,
I set the data into a table with: cellTable.setRowData(myList);
But what is the proper way to perform CRUD on this list, or retrieve the
whole data of the CellTable?
Especially I'm interested in auto-update of the list when the user changes
something within an EditTextCell.
Should I just keep a private List<Foo> in the same class where the
cellTable resides? Or should this be done using a ListDataProvider<Foo>?

That's easily done with FieldUpdaters on your Columns.

> cellTable resides? Or should this be done using a ListDataProvider<Foo>?
The one thing data providers do is listening to range-change events (i.e.
pagination events); they also make it easier to have multiple simultaneous,
synchronized views of the same list, but that's rather an edge case. Data
providers also help decoupling your data retrieval from your "screens"
(activities, presenters, views, you name them).
This is all independent from the above re. FieldUpdaters.

Hi,
I want to create a header with 2 elements: one aligned inline to the
middle, and some aligned right.
The following works fine in Firefox, but in Chrome there is a linebreak
between the two FlowPanels. What is wrong with this code:
.inline { display: inline-block; }
.right { float: right; }
<g:FlowPanel>
<g:FlowPanel styleName="{style.inline}">
<g:Label text="inline" />
</g:FlowPanel>
<g:FlowPanel styleName="{style.right}">
<g:Label text="right1" />
<g:Label text="right2..." />
</g:FlowPanel>
</g:FlowPanel>
Thomas Broyer <t.broyer@gmail.com> Feb 15 06:25AM -0800
Try moving the .right FlowPanel before the .inline one; and/or giving it
display:inline-block too.
