Re: is code using DateTimeFormat not testable?
In my opinion, your question is extremely relevant is code using DateTimeFormat not testable? I found your thread here because I converted some code from SimpleDateFormat to gwt DateTimeFormat.

Re: How to set stylesheet on a per page basis?
2011/10/19 Mike Dee mdichiapp...@gmail.com After doing some testing, it doesn't looks like this works as expected.

Re: Editor doesn't show server validation errors
After some debugging I found that cloning is the reason why server side validation errors are not pushed to editors. Server side validation creates ConstraintViolation instances with a reference to the validated proxy. But as I have a cloned proxy which gets saved and thus validated the ConstraintViolation has a reference to that clone. The editor framework fails to convert ConstraintViolation to EditorError because it does now know the clone found inside ConstraintViolation and could not retrieve a list of editor delegates from its internal data structure (see: SimpleViolation.pushViolations(): 117). Not quite sure if I can solve this issue. I need the clone to be able to continuously edit the proxy while saving it in the background. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: PasswordTextBox: Making password character visible for a moment
Hi Raja, I think the way to achieve this is by making use of the keyboard listener functionality. This might need some explicit code. First you define a normal textbox, then when the user types something, set a keyboard listener, and then a timer. Then you can temporarily store the that character of the password in some string which keeps getting appended as and when the user keeps typing. And with every keyboard key-in, call the keyboard listener, then the timer say for 100 ms and then replace that with a * or #. That should get your logic working. Just for your info, the only reason why this was introduced in cellphones was because, in a cellphone, each button might correspond to multiple characters. If you implement this algorithm in normal web-pages (which I feel would not really be needed) then you might need to have a specific logic to distinguish between a browser-access and cellphone-access and enable this logic only for the browser version and have a normal password textbox for the cellphone version. Just think over!!

Re: How to set stylesheet on a per page basis?
There are two ways to add style sheet for one page
1. In ui.xml specify the file name of css file Ex:ui:style
src=client-specific.css /
or Inline style sheet with in ui.xml file Ex: ui:style/
ui:style
2.Generate your css file. The css file is referenced by CssResource
interface. Specify your Css file in Source attribute of
ClientBundle.
interface MyCss extends CssResource
{
String YourCssName();
}
interface MyResources extends ClientBundle {
@Source(my.css)
MyCss css();
}
MyResources resources = GWT.create(MyResources.class);

celltable and MultiSelectionModel: manual element changes (like element-title) disappear
Hi guys! I'm having some strange issue - I don't know whether it's a bug or just my own mistake. I'm having a list of Characters (name, age, class etc.), which are displayed using a CellTable. It all works fine except that I haven't found a good way to add tooltips to the row elements. In order to solve my problem, I'm doing something like this: celltable.getRowElement(rowNumber).getCells().getItem(0).setTitle(tooltip); I'm doing this for each column-element of a given row (e.g. name, age, class etc.). Now HERE comes the problem: whenever the selection is changed (e.g. I check/uncheck the checkbox or the classes used for styling are changed for any reason) - the tooltip disappears. Is there a way to preserve the set tooltip? Or if I were to reapply the tooltip - how would I go about doing that?

Re: celltable and MultiSelectionModel: manual element changes (like element-title) disappear
You'd rather use a Cell that generates a title= attribute. The reason for the title= disappearing is that CellTable redraws, and does so by generating the table and using innerHTML, and thus replacing the whole DOM subtree. In GWT 2.5, you'll be able to provide your own CellTableBuilder (you'll probably subclass the DefaultCellTableBuilder) and add a title= attribute on any tr or td you'd like. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to set stylesheet on a per page basis?
If I do #1, the styles appear in all the pages (in the entire
module). The app has several views and each view has its own UIBinder
file (.ui.xml). In the one specific view that I want additional CSS I
added:
ui:style src=extracss.css/
When I run the app and look at the view, the styles work.
BUT, when I look at the CSS using Firebug, the styles defined in
extracss.css are in all the pages in the app. It is like adding the
ui:style in one .ui.xml caused GWT to include it in all pages.
I can try #2.

done?

JUnit testing gwt app with multiple modules
I am currently using gwt 2.3 and smartgwtpower 2.5 nightly and using Eclipse on Linux. My web app is using common code, developed in house, and packaged to a jar called commonsmartgwt.jar. In this jar is the entry point class and has its own gwt.xml file. In my web app's gwt.xml file I inherit from the entry point class inherits name=common.code.Common/ and I use the entry point is common.code.client.Common as my web app's entry point. All my classes in my web app extend classes in the common code. Compilation works fine but when I try to run a test, I get the following error. Unable to find common/code/Common.gwt.xml on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source. If I create the folder common/code/ under classes and extract the .gwt.xml file from the commonsmartgwt.jar and put it in that directory, I get a different error. com.google.gwt.junit.JUnitFatalLaunchException: The test class 'my.package.client.MyFirstTest' was not found in module 'common.client.Common'; no compilation unit for that type was seen at com.google.gwt.junit.JUnitShell.checkTestClassInCurrentModule(JUnitShell.java: 743) at com.google.gwt.junit.JUnitShell.runTestImpl(JUnitShell.java: 1346) at com.google.gwt.junit.JUnitShell.runTestImpl(JUnitShell.java: 1309) at com.google.gwt.junit.JUnitShell.runTest(JUnitShell.java:650) at com.google.gwt.junit.client.GWTTestCase.runTest(GWTTestCase.java:441) at junit.framework.TestCase.runBare(TestCase.java:127) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:118) at com.google.gwt.junit.client.GWTTestCase.run(GWTTestCase.java: 296) at junit.framework.TestSuite.runTest(TestSuite.java:208) at junit.framework.TestSuite.run(TestSuite.java:203) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java: 130) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java: 38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java: 467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java: 683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java: 390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java: 197) Is there a way to Unit test this application.

RequestFactory Refractory Long Id into String Id, so I can use App Engine Keys??
I think the RequestFactory ID system should be a String and not a Long so we can use child collections on App Engine easily. App Engine keys can be reflected as Entity(1)/Entity(2)/Entity(3)... . I would think this wouldn't require a Key serialization routine. Any Thoughts?

ConsoleLogHandler not working as expected in IE?
We ran into an issue with console logging on IE, and we traced down to the isSupported() method in ConsoleLogHandler. Looks like the isSupported() method doesn't take into account IE's native console logging capabilities correctly. The method does the following check: (typeof(window.console.log) == 'function') ... which fails on IE as window.console.log is an object. I did a quick search for issues, but didn't find anything related ConsoleLogHandler. Has anyone run into the same issue?

I just figured I ship the Ids as string, and its working fine. I noticed the source was not particular to what type of ID it is. So I'll serialize the App Engine key.

celltable scrolling and dynamic loading
Hello, I've been using teh GWT Celltable for some time but have been unable to come up with proper scrolling that triggers additional calls for data. I've seen the cellList example and have incorporated into into my celltable however the sample calls for data only when the scrollbar reaches the bottom. This produces an undesirable water pump affect. For example , consider the possibility of 10,000 candidate rows for which only 100 will be returned with any given call for data. In the current sample(ShowMorePagerPanel) , the size of the scrollbar is determined from the 100 rows initially returned and then shrinks accordingly as additional groups of 100 rows are added. What I would like to see is a scrollbar size that reflects the 10,000 candidate rows and to have the triggering of new data occur upon scrolling a small segment of the scrollbar. That way I can quickly scroll to the last 100 of the 10,000 rows by just scrolling to the bottom once. thanks David -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Enforcing sequencing of asynchronous event handling code
Hi,
Our Goal:
On the client side, events on the bus should be processed one at a
time by their handler, in order, FIFO.
Details:
Just took over a pretty involved GWT/Spring/Hibernate/Gilead system.
App
works great; it is super fast, snappy, and responsive. One problem
sitting
in the backlog, though, results from the fact that some single-
threaded
server side code is entered by multiple threads working on the same
piece
of data. End result is that the data gets stomped on. When we add
uniqueness constraints we see that a duplicate key exception is
occurring,
so we know something is happening that should not.
From a user perspective, this should never happen, because they
move along on their way using the app, clicking on things, in
sequence,
and that sequence makes sense, and in doing so it adds events to the
event bus... basically EVT_A - EVT_B - EVT_C - ... and so on. EVT_A
handling should complete before EVT_B handling and EVT_B handling
should
complete before EVT_C handling and so on and so forth.
In practice a problem manifests though, because on the client side the
handlers all fire off right away (as one would expect) resulting in
multiple threads computing against the same data in the same place.
Here
is how it looks:
TIMESTEP 1
EVT_A (DATA_COPY_1) - HDL_A - SVR_CALL -
compute_method(DATA_COPY_1)
EVT_B (DATA_COPY_2) - HDL_B - SVR_CALL -
compute_method(DATA_COPY_2)
EVT_C (DATA_COPY_3) - HDL_C - SVR_CALL -
compute_method(DATA_COPY_3)
On the server side, multiple threads (coming from the handler servlet)
end up entering compute_method at the same time, and behold, things
blow up.
So, our desired behavior is that for certain paths of work, we want
sequencing. Looking at the app further, we decided that rather than
track
down all of the unique flows, that instead the entire app should
behave such that EVT_* are handled in order, period. This makes sense
from
a user perspective, and by following a blanket-approach we could force
the
entire app to just do the right thing so to speak. The above would
look
more like this where queue is the event bus and handler code executing
is all of the work no matter client-side presenter or server side that
it
takes to satisfy the goal for that event:
TIMESTEP 1
QUEUE {empty} HANDLER_CODE_EXECUTING{none}
TIMESTEP 2
QUEUE{EVT_A} HANDLER_CODE_EXECUTING{none}
TIMESTEP 3
QUEUE{EVT_B} HANDLER_CODE_EXECUTING{EVT_A}
TIMESTEP 4
QUEUE{EVT_C:EVT_B} HANDLER_CODE_EXECUTING{EVT_A}
TIMESTEP 5
QUEUE{EVT_C:EVT_B} HANDLER_CODE_EXECUTING{none}
TIMESTEP 6
QUEUE{EVT_C} HANDLER_CODE_EXECUTING{EVT_B}
TIMESTEP 7
QUEUE{EVT_C} HANDLER_CODE_EXECUTING{none}
TIMESTEP 8
QUEUE{empty} HANDLER_CODE_EXECUTING{EVT_C}
TIMESTEP 9
QUEUE{empty} HANDLER_CODE_EXECUTING{none}
Talking more we looked at client-side vs. server-side to make this
change.
We felt like queuing up all requests on the client side would have the
benefit of being real-Java, but the downside is that queueing up
threads
seems to go against the spirit and architecture of the server itself
(Tomcat).
Client side seems like equal amount of work, but we have the added
benefit
of not having to worry about out-of-order client requests and so on.
At this
point we plan to make the change on the client side. One option we
decided
against was using the UI to block the user from doing things out of
sequence
or before they should be doing them, and if we had been able to do
this
from the start we would have, but at this point feel that adding the
global
queuing would be much less work than identifying all of the code paths
that can result in out-of-order-execution-errors.
Our goal: on the client side, events should be processed one at a time
by
their handler, in order, FIFO.
Not sure of the approach yet, haven't dug in deep. Curious to know
what you
think about this problem we are facing, our proposed solution, what is
the standard GWT way to manage this, and how you might do it.
While this feels like a big change, gotta imagine that our situation
is not
totally unique because indeed sometimes you need sequencing.
Look forward to your thoughts and advice.
Best wishes,
Grant

Re: Enforcing sequencing of asynchronous event handling code
On 10/19/2011 12:45 PM, Grant Rettke wrote:
Hi,
Our Goal:
On the client side, events on the bus should be processed one at a
time by their handler, in order, FIFO.
Some (sort-of mutually exclusive) solutions:
1) Implement condition variables
(http://en.wikipedia.org/wiki/Condition_variable)
2) Only fire Event B after Event A processing occurs. You might need
extra events e.g. Event A prepare, Event C prepare, ... Event N
prepare. After handling these events, the secondary events, Event A,
Event B, ... Event N are fired. Some implementations create three
basic events, Prepare, Acknowledge, Commit and pass identity
information in the event cargo.
I /think/ (it's hard to tell, even though your description is quite
detailed), that (1) will be your best bet. Consider a scheme that
implements an event-specific bit mask that's checked against the
condition variable. Each event handler delays via
Scheduler.get().scheduleIncremental(new Scheduler.RepeatingCommand(){})
until the bit(s) corresponding to the predecessor event(s) are set in
the condition variable.
There are other ideas, such as a central event handler. However, the
problem with that and related solutions is that they don't scale well,
and have a tendency to tightly couple unrelated code. The advantage of
(1) is that the event handling code remains, but it's gated by logic
that checks a condition variable before proceeding. After event
processing completes, the condition variable is set to the appropriate
value.
In your scenario, Event A is bit 0, event B is bit 1, Event C is bit 2.
A is not gated, and sets bit zero
B is gated by bit zero set, and sets bit one
C is gated by bit zero and bit one set, and sets bit two.
Details:
Just took over a pretty involved GWT/Spring/Hibernate/Gilead system.
App
works great; it is super fast, snappy, and responsive. One problem
sitting
in the backlog, though, results from the fact that some single-
threaded
server side code is entered by multiple threads working on the same
piece
of data. End result is that the data gets stomped on. When we add
uniqueness constraints we see that a duplicate key exception is
occurring,
so we know something is happening that should not.
From a user perspective, this should never happen, because they
move along on their way using the app, clicking on things, in
sequence,
and that sequence makes sense, and in doing so it adds events to the
event bus... basically EVT_A - EVT_B - EVT_C - ... and so on. EVT_A
handling should complete before EVT_B handling and EVT_B handling
should
complete before EVT_C handling and so on and so forth.
In practice a problem manifests though, because on the client side the
handlers all fire off right away (as one would expect) resulting in
multiple threads computing against the same data in the same place.
Here
is how it looks:
TIMESTEP 1
EVT_A (DATA_COPY_1) - HDL_A - SVR_CALL -
compute_method(DATA_COPY_1)
EVT_B (DATA_COPY_2) - HDL_B - SVR_CALL -
compute_method(DATA_COPY_2)
EVT_C (DATA_COPY_3) - HDL_C - SVR_CALL -
compute_method(DATA_COPY_3)
On the server side, multiple threads (coming from the handler servlet)
end up entering compute_method at the same time, and behold, things
blow up.
So, our desired behavior is that for certain paths of work, we want
sequencing. Looking at the app further, we decided that rather than
track
down all of the unique flows, that instead the entire app should
behave such that EVT_* are handled in order, period. This makes sense
from
a user perspective, and by following a blanket-approach we could force
the
entire app to just do the right thing so to speak. The above would
look
more like this where queue is the event bus and handler code executing
is all of the work no matter client-side presenter or server side that
it
takes to satisfy the goal for that event:
TIMESTEP 1
QUEUE {empty} HANDLER_CODE_EXECUTING{none}
TIMESTEP 2
QUEUE{EVT_A} HANDLER_CODE_EXECUTING{none}
TIMESTEP 3
QUEUE{EVT_B} HANDLER_CODE_EXECUTING{EVT_A}
TIMESTEP 4
QUEUE{EVT_C:EVT_B} HANDLER_CODE_EXECUTING{EVT_A}
TIMESTEP 5
QUEUE{EVT_C:EVT_B} HANDLER_CODE_EXECUTING{none}
TIMESTEP 6
QUEUE{EVT_C} HANDLER_CODE_EXECUTING{EVT_B}
TIMESTEP 7
QUEUE{EVT_C} HANDLER_CODE_EXECUTING{none}
TIMESTEP 8
QUEUE{empty} HANDLER_CODE_EXECUTING{EVT_C}
TIMESTEP 9
QUEUE{empty} HANDLER_CODE_EXECUTING{none}
Talking more we looked at client-side vs. server-side to make this
change.
We felt like queuing up all requests on the client side would have the
benefit of being real-Java, but the downside is that queueing up
threads
seems to go against the spirit and architecture of the server itself
(Tomcat).
Client side seems like equal amount of work, but we have the added
benefit
of not having to worry about out-of-order client requests and so on.
At this
point we plan to make the change on the client side. One option we
decided
against was using the UI to block

Validation in RequestFactory is done after the object graph has been
reconstructed but before any service method is invoked. It's the only
place
where validation errors will lead to onConstraintViolations being called
back on the client side (for all the Receivers attached to the
RequestContext).
When service method invocations are processed, each one can succeed or
throw, independently of the others, and will cause the onSuccess or
onFailure of the Receiver _for that particular invocation_ (the one
passed
to the to() or fire() method of Request –but not the fire() method of
RequestContext!–) to be called back.
FYI, the global Receiver's (the one passed to the fire() method of
RequestContext) onFailure method is only called when the object graph
cannot
be reconstructed or serialized on the server-side; in that case, the
onFailure of all Receivers is also called. In any other case (except
onConstraintViolations), onSuccess will be called (even if all
invocations
failed).
