Tnx for the good words.
We see what singular will bring out when it becomes production candidate,
and then I can do something.

This one is pretty much tested, we use it in one of our inhouse projects
with almost no problems at all.

 Keep up your good work. Perhaps it could be combined with gwt singular?

Re: To smart GWT or not

2010-12-04 Thread Blagoja Chavkoski

Hi,

Just small overview

I have used Gwt, Gwt ext and Smart Gwt...all are pretty ok for the power
used to be developed, they are produced by very small number of programmers
and
we all know that, so we are not talking for JAVA core libs or C# core libs
or something like that.. and they have bugs also:)
In other case they are very good, you dont have to re-envent the
things..just use it in most casses, in some cases when u need somthing
special or its present some bug, u can extend and provide the fiture by your
self..so thats why they are free :)

2010/12/4 Jaroslav Záruba jaroslav.zar...@gmail.com

My experience with SmartGWT was bad and while I'm not saying SmartGWT
is complete rubbish, obviously, I think it is right thing to do to
share your experience when asked.
I said couple of times my experience is 1 year old. Also there are
many people who share this view of SmartGWT.

I had to do some compromises with SmartGWT, some of them having origin
in SmartGWT being a new platform for me (i.e. lack of knowledge), but
there were some clearly caused by SmartGWT being buggy.

You accused me of giving baseless opinions. That is just low.

One issue that stuck in my mind was the last one: a new and valid
record not appearing in a TreeGrid, in ListGrid everything worked as
charm. Later, in one night build, it has been fixed. That was too late
for me though.

My apologize to all readers, this is my first and last response to
Sanjiv here.

On Dec 3, 4:54 pm, Sanjiv Jivan sanjiv.ji...@gmail.com wrote:
Jaroslav,
If you're happy with GWT that’s great but please do not make such vague
and
baseless claims about Smart GWT.

The fact that you don't like critics does not make it baseless. (Same
as when you FIX a bug after a report it probably wasn't INVALID.)

3 of the 7 issues that you filed were invalid

This is what you call an invalid bug:
http://code.google.com/p/smartgwt/issues/detail?id=338
In a nutshell: One particular column type (Integer) at one particular
position (the first column) causes an error. Because you're not
supposed to have numbers in the first column...?
Something is wrong when you get asked why do you need number in the
first column?

Another one, this one you fixed later but marked it as invalid
anyways:
http://code.google.com/p/smartgwt/issues/detail?id=343

http://code.google.com/p/smartgwt/issues/list?can=1q=reporter:jarosl..
.And
when you were advised how to implement a warning dialog before record
deletion on this issue that you filed (
http://code.google.com/p/smartgwt/issues/detail?id=325), you responded by
you
are sad. Nice way to show your appreciation when using a free product.

Your 'WontFix' for a _month_ old report came literally _minutes_ after
you accused me of abusing issue tracker in another forum. It is
obvious that my response was related to your personal approach, rather
than your so-called advice. (I had my own workaround by the time I
made the report.)
Abusing issue tracker in this case actually meant reporting an
issue without discussing it in the forums, which was not suggested in
the new issue report description. And therefore it happened to many
people before me, which you admitted. (But that did not stop you from
claiming I'm the only one doing that.)
Later you fixed that, added the note in the description, and now
you're counting it in those 3 invalid reports.
I said 'thank you' nevertheless.

I had only positive experience with other SmartGWT staff members,
Isomorphic namely.

Sanjiv

Based on my own experience, SmartGWT is rather risky choice even
though it might look nice at first.
SmartGWT: 2.5*

While GWT might be slower sometimes (when you need some super-special
widgets) I believe in the end you will be better off that way. Even
more it applies now with GWT 2.1.
GWT: 4.5*

Re: How to keep row selected after pagination grid refresh?

2010-11-20 Thread Blagoja Chavkoski

This question is for ext gwt forum, but i had implemented some code close to
this one, and I had the same problem!!
Its interesting that I notised the problem is on adding the html css style
for the selected row..its just not showing,
the related model row is correct and all related listeners are fired...but
the view row style is never set or set and cleared...
I investigated in the GridView class but till that point all was ok and
fired prop ..it looks like something is going on after that..
the relation between gwt(resp for the css styles adding in widget, and the
component class extension from ext) but no
time to spent more and just continue without it..:)

regards and hope u gonna solve it,
if u do..u can notify here also...

The easiest way would be to have the normal callback, which gets the
latlng array. Then in the onSuccess() Method changing the marker
positions with a for loop and a delay. I tried that, but i couldn't
find a possibility to make this delay

Is it possible to do that like that, or do i have to make already the
callback with the delay? Does that mean, that i have to make two
callbacks, one which gets the array and the secon in a for loop?

Thanks and best regards from switzerland.

GWT is Javascript, at least what the user sees on the website.

One idea, is to get all the data from your server for a ship's route
as an array of lat/lng objects, then set up a Timer() object that
calls your callback every 30ms or so, and you just set the map marker
position to the next entry in the lat/lng pair. For faster animation,
jump further in your array, or decrease the 30ms to 15ms, etc.

Hi all,

For an actual project, we need to evaluate movements of motor-ships.
The position datas are sent from a gps router on the ships and are
saved in a database on our server. One of our goals is to show the
driven way of one or more ships between a specified time as an
animation. Our Application is written in Java with GWT. What we have
already is, that the driven way get's drafted like a normal route in
google maps. What we want is, to show for example all ship movements
for one day in fast motion.

My actual problem is, how to animate the driven way. Is it possible to
do the animation in GWT, or do we need to use javascript?

I hope, someone can give me some ideas.

Thanks a lot.

Hi all,

First tnx for the replay!

I tried Fernando's method and cant get it work, I also dont undertend how to
package if I doit this way
do i have to add gwt.war file in the ear file or...

Abouth the local way Jin is saying, I tried this also but not working again
(I tried this long time ago)
and I also put the war file in the ear, by logic thinking that running in
the same container have to find the ejb.jar
this was my structure I had:

App.ear holding:
ejb.jar
gwt.war
and all related libs

and in the application.xml i set the module for gwt.war also:
module
web
  web-urigwt.war/web-uri
  context-root/gwt/context-root
/web
 /module

But in that point of action...I was not able to make it work..
I was getting nullPointerExp on the local ejb (Not created :) )

So what is your thinking?

I thinking is that i have some problems with how I make the packaging (not
my best side also:) )

Regards,
B

 Hi Blaze,

 I haven't tried Fernando's method, but it sounds like a convenient way
 to integrate the client side with EJB's.

 The method I have successfully used is to simply call the EJB's from
 the GWT RPC servlets.
 That code snippet you wrote is the right idea.  The local interface is
 fine, since the GWT RPC servlet will be running in the same VM as the
 EJB.
 I'm using this method with Glassfish v3.

 I had to put the GWT code in the same project as the EJBs but that
 might be due to my lack of understanding of how to package EARs
 properly.

 Cheers,

 Jin

Re: GWT and concurrency

2010-09-19 Thread Blagoja Chavkoski

Hi,

As Stefano wrote...ur loop will never end..:) and no other cycle can be
executed.
This is a concurrency topic and threading, try to create in java(or any
other language)
a thread with while(true) do something, and try to confine some other
thread(some other work) to be done on this thread...
ul see that this can never be done:)

As a example:

Make a java gui with a one button...and inside the EDT(swing thread) make a
endless loop...ull se that ul never be able to catch a
event fired from the button...(this is because the EDT thread will never go
to idle and never get a new task(in case of java a new runnable or calable)
out from the EDT- que.

This is the famous Producer-Consumer pattern.

so basically here is done the same(a program written in a programming
language dose it for u, and its called browser, so the browser engine is the
one responsible for this...and thats why I dont like web programming:)
i dont have the overview of what is happening, and usually strange things
happens:) )

I appreciate that with JavaScript interpreters executing in one thread
there will never be any *true* concurrency. However it seems perfectly
possible for concurrency issues to arise with the way that
asynchronous callbacks are used A simple example is if I am
continuously checking the value of a variable x, and then incrementing
it:
while(!stop) {
int i = x;
x = i+1;
}

Once the event occurs, the handler prints the variable and sets a flag
that causes the incrementing to stop:
print(x);
stop = true;

The intended behavior might be that the final value of the counter is
printed. However if the event handler is invoked right after the
assignment 'int i = x', the value will be incremented one more time
after it is printed, which is a concurrency bug.

In such cases the synchronized keyword could have been used to define
pieces of code which must not be interrupted by other pieces of code
in such way. In plain Java the synchronized keyword provides an easy
way of dealing with such issues. The problem I described in my first
post is very similar to this in nature and I am lost as to what to do.

I hope this makes what I mean a bit clearer. Of course I am not
excluding the possibility that I just misunderstood somthing about how
the GWT/JavaScript eventing mechanism works.

Thanks,

Excuse my ignorance about semaphores/mutexes/preemption details, but
how can there be concurrency issues if things never execute

I would say take out all inheritance for languages in the gwt.xml module,
and re-compile the app and try what will happen...

Also on withc browser you test..let me say..u can say to the compiler not to
create all the permutation, maybe for a try just
for firefox..(the compile time would be much fester also:) )

But try first the one before...

Hi all,

I have developed for a while now on a gwt 2.0.0 and maven project.
But recently i did a maven clean install on the project to generate
the war file in the target folder.

Now when i tried to do a mvn gwt:run again it sais that the module may
need to be (re)compiled...
I can't get it fixed.

I even checked out an older version of the project out of the
repository in an new workspace, but still i get the error.
And i am sure that that version was working when i checked in the
changes...

Any idea pls??

I'm really stuck here

kind regards,
Thomas

Re: GWT. commons.lang.StringUtils

2010-07-25 Thread Blagoja Chavkoski

Hi,

You cant use any java.jar file in gwt without having the source code
included in the jar and having
the gwt.xml file pointing to the source classes...why u need this?! because
gwt compiler needs to compile this classes
to js! gwt by default compiles all classes in client and all classes in
shared to js, and bacause u have a import for commons gwt try's to compile
this import also!!! but there is no source code and no gwt.xml file in the
jar

If you dont understand what im saying:) open one of the normal .jar lib
files used in gwt and youll see that inside u have all I wrote before!
(source classes and gwt.xml)

Important!!

If having a lib that inside uses other lib..than u need the same thing for
this imported lib:)...so basic dont use in client and shared any java lib
other then the
normal java lang libs(the compiler have the source for them by default)...to
see what im talking...try to add insted of ArrayList...
ConcurentArrayList...ull get the same problem..because the compiler dosent
recognize this libs also:))

regards blaze,
Hope i was of help...

Subject: GWT. commons.lang.StringUtils

Hi,

I am trying to search between two Strings using the
StringUtils.substringBetween() in my project. I have imported
org.apache.commons.lang.StringUtils; in my Entry Point java file . I
have included common-lang.jar in my lib directory and in my project
path. I have also modifed my gwt.xml
inherits name=com.googlecode.gwt.commons.long.Long/. I dont know
if this is right or wrong.

The Java Compilation goes through without any Errors . but if i do a
GWT compile i get the following error

[ERROR] Line 190: No source code is available for type
org.apache.commons.lang.StringUtils; did you forget to inherit a
required module?
lib/gwtx-1.5.2.jar!/com/googlecode/gwtx/java/util/emul/java/util/regex/

I want to know if its possible to includes
org.apache.commons.lang.StringUtils in GWT and how can i do the
inherits in my GWT.XML file or i am digging in the wrong way.

Please HELP.
Any help would be appreciated. Thank you very much.

Re: New Java Documentation Tool from Sencha

2010-07-20 Thread Blagoja Chavkoski

Because i like to have the bought libs used, GWT and GXT for my projects...
and to be open on what future to use I create one abstract class extending
one of the gxt widgets
...usually ContentPanel..because is the most rich one..and in this class I
add all the gwt future I like to have.
Just implement some interfaces and so on... copying the code from the gwt
implementation will pass ok normally.
If somewhere I have problems implementing something with this class...i need
some more specific one...then i do the same
with that one..

Its yours very fest implementation..but you have to be at list advance in
programming

Are there any plans when will sencha use standard GWT APIs ?

Like HasText, HasValue, HasWidgets interfaces?

For example,
TextArea does not implements any of interfaces above but the widgets
itself should hasve such an implementations.

Thanks,

For the last 15 years, java developers have have used JavaDoc to
create API documentation. We're all familiar with JavaDoc's dated
interface, but we're giving it a major face lift and hope you like the
results.

We'd love to know what the GWT community thinks and what other
javadocs you'd like to see in this format. (hint: GWT docs coming
soon!)

Re: Remove event handlers or not?

2010-07-19 Thread Blagoja Chavkoski

Hi,

I have some small question related to events..but other way around:
How can we fire a native(browser) event in gwt 2.xx ?! On 1.6 there was a
method.Document.fireXXXEvent
but not in the newer relies.

tnx!

Where do you see the automatic removal of handlers? There's nothing
when a widget is unloaded, and I can't find anything that would do any
cleanup. Maybe there's some code somewhere to do cleanup as the app
is shutting down?

onDetach calls setEventListener(getElement(), null) which is enough to
mitigate memory leaks:
http://code.google.com/p/google-web-toolkit/wiki/DomEventsAndMemoryLeaks
And on window.onunload, all RootPanels and wrap()ed widgets are
detached, so their onDetach method is called (which recursively detach
their children).

Re: Error while running my web app....

2010-07-19 Thread Blagoja Chavkoski

Compile the application...u made a big changes probably (I would say u
implement locale or something like that )
so the app dose not have all needed permutations for the pages.

Just compile, if using gwt plugin for eclipse the red icon..if using stand
alone with ant build then call compile target from the build file
