Re: How to remove a row from Flex Table

2011-10-12 Thread Sudhakar Abraham

First count the number of rows in FlexTable using getRowCount()
method.  Remove specific row from flex table using
removeRow( int row).

Ex:

  int count = myFlexTable.getRowCount();

  for (int i = 0; i  count; i++)
  {
  myFlexTable.removeRow(i);
  }

That code won't work. You'll probably get an IndexOutOfBoundsException. The 
first time through the loop, you will remove row 0. What was originally row 1 
will then be row 0, and what was originally row 2 will be row 1 etc. So on the 
second time through the loop, you remove row 1, but that is the row that was 
originally row 2. So the row that was originally row 1 would never be deleted. 
When you get far enough through removing rows, you'll get an exception.

To delete all the rows one at a time (rather than calling 
myFlexTable.removeAllRows()), try something like this:

  int count = myFlexTable.getRowCount();

  for (int i = count-1; i=0 ; i--)
  {
myFlexTable.removeRow(i);
  }

or else something like this:

  int count = myFlexTable.getRowCount();

  for (int i = 0; i  count; i++)
  {
myFlexTable.removeRow(0);
  }

Re: Full page in GWT or just parts?

2011-10-12 Thread Uemit

I think GWT is best utilized in a full page scenario because of code 
sharing of re-usable components.
If you go the other route and just embed GWT code in different host pages 
(i.e. application with multiple entry points) you lose the benefits of 
javascript code re-use of reusable components because every entrypoint will 
have its own module.nocache.js file which has to be transferred to the 
client. If you create a re-usable component (let's say a CellTable 
component) which is used in different places  (in both entry points) the 
same code will be part of the module.nocache.js file and thus downloaded two 
times. 
It probably doesn't make a big difference for small web-sites where some 
parts are done with GWT but for complex apps where you might re-use a lot of 
components it might be an issue. 
However in case you go with the one host page (one entry point) solution you 
will probably not use any of the your backend's flow controls (MVC) but it 
will solely act as a data-backend.

Re: Full page in GWT or just parts?

2011-10-12 Thread Ed

@Uemit: I agree but not completely as your comment aren't suited for
larger app's (in my case).

Don't forget that the current code splitting isn't perfect such that
the left-over fragment can become rather large, as in my case.
As such, that the simple login screen results with a big initial load,
whereas if I split it from the core application part, it becomes very
small. This is important as you don't want the user to wait too long
for the login screen to appear.

But of course I would like to make it as one gwt app, but this
currently results in bad results.

Apart from the code reuse, for me at this moment it's all about
resource management that GWT performs well as explained above.

Use header mouse events to resize table columns

2011-10-12 Thread P.G.Taboada

Hi,

I am working on a table header that captures mouse events in order to
resize the table columns.

It is woking property, as long as I do not move the mouse to fast and
don't leave the header area.

So I took a look at the SplitLayoutPanel to see how this has been
solved there. The SplitLayoutPanel uses a full screen div (a glass
panel). So far so good, but as soon as I try the same approach, I stop
receiving events.

Looking at the dom, the only difference I see is that the divs in the
split layout panel have different zIndex values that my header haves,
but I am not sure if this is my problem and where the zindex is being
set in the split layout panel.

Could someone provide me some directions on how to do the glass panel
magic and still receive the events?

select language or country from a drop down list

2011-10-12 Thread gerry

Hi all,

I am building an application where the user needs to specify the name
of a work of art, like a poem or song, and I need him to specify its
language. I want to make it possible that he can choose the language
from a drop-down list, and I also want to know the three character
code of the ISO-639-2 standard for the language he selects so that I
can store it in my database (like Eng for English, Ger for German
etc.).

Is there a standard way I can select language in gwt using a drop down
menu and mapping them to the ISO standard code?

I also want to do the same thing for selecting countries through a
drop-down menu and mapping them to their ISO-3166 code (FR for France,
DE for Germany etc.).

Thanks a lot,
Gerasimos

What you want sounds like what I do with

addItem(java.lang.String item, java.lang.String value). The item is
what the user sees (the language) while value contains what you're

Hi Thad,

Thanks for your reply. In your suggestion I will have to type all the

a more automated way, like I could do if I could use the

not injecting an entityManger @PersistenceContext

Hi,

I'm trying to integrate an EJB-Project (which is connected to a
database by hibernate) into my GWT (in more detail move from CDI-Weld
implementation to GWT).

I created a new ejb-project only containing my entities and their
clients.

Within my GWT-project I reference to my ejb-project and included the
compiled class-files into WEB-INF/classes as described everywhere.

From my ServerServiceImpl the entity are reached, my stateless-class
is called, but the entityManager remains null as I try to reach my
database.

my code:

ServiceImpl:

private Product product;

@EJB(name = Product )
public void setProduct(Product product)
{
this.product = product;
}

public DatabaseBuilderServiceImpl()
{
}

public boolean createDefaultDatabaseEntries()
{
boolean returnvalue = false;

returnvalue =  product.createTestEntry();

return returnvalue;

my Interface:
  public interface Product
  {
ListProductEntity findAll();
ProductEntity getProductBy(String productSymbol);
ListOptionEntity getOptionsBy(ProductEntity currentProduct);
ListVariantEntity getVariantsBy(ProductEntity currentProduct);
boolean createTestEntry();
  }

my stateless-bean:
  @Stateless(name = Product)
  @Local(Product.class)
  public class ProductHome extends HomeBaseProductEntity implements
Serializable, Product
  {
@PersistenceContext(unitName=sung.app.kylintv.ejb)
protected EntityManager entityManager;

@EJB
protected Option sessionOption;

/**
 * @return List of available  products
 */
@SuppressWarnings(unchecked)
@TransactionAttribute(REQUIRED)
public ListProductEntity findAll()
{
return entityManager.createQuery(SELECT p FROM ProductEntity
p ORDER BY p.id).getResultList();
}

@TransactionAttribute(REQUIRED)
public ProductEntity getProductBy(String productSymbol)
{
return (ProductEntity) entityManager.createQuery(SELECT p FROM
ProductEntity p  WHERE p.name = :productSymbol ORDER BY
p.id).setParameter(productSymbol, productSymbol).getSingleResult();
}

currentProduct)
{
return entityManager.createQuery(SELECT p FROM OptionEntity p
WHERE p.product = :currentProduct ORDER BY
p.id).setParameter(currentProduct, currentProduct).getResultList();
}
  }

the function inside my bean is reached, the entityManager is null.

Re: not injecting an entityManger @PersistenceContext

the real function called starts like this:
@TransactionAttribute(REQUIRED)
public boolean createTestEntry()
{
try
{
System.out.println(TEST creating Data BEGIN);

ProductEntity currentProduct = new ProductEntity();

//  fill FIRST product 
currentProduct.setName(bo_product_europe_basic_name);

currentProduct.setDescription(bo_product_europe_basic_description);

entityManager.persist(currentProduct);

on first call for the entityManager the function fails.

Re: select language or country from a drop down list

2011-10-12 Thread Alan Chaney

What you can do is to write a small java application to generate the 
list for you, using the static Locale class methods as you mention below 
. You can create json, text or xml and import it into your drop down list.


This will save you a lot of tedious typing.

Hi Thad,

Thanks for your reply. In your suggestion I will have to type all the
countries and their codes myself, while I was hoping I could do it in
a more automated way, like I could do if I could use the
java.util.Locale package (method static String[] getISOCountries() for
example) which is not supported by GWT. But it seems I can't do
anything simpler than what you suggest.

 run it in debug mode (java debugger), wait for it to get stuck, press
 pause and look at the threads. you should see what they are doing.

 a simple thread dump might also help

Thanks.  I did this and the threads are this:

 UnitCacheLoader (Running)
 GWT Update Checker (Running)
 Code server listener (Running)

So it looks like it's trying to go somewhere and check for updates and
is getting stuck.  Is there any way to turn this off?

ListBox CSS with GWT Clean Theme

Hi Everyone,

I recently started using the newer Clean theme for GWT. I prefer it to
the standard theme but don't like the way that ListBox looks. Is there
any way that i can get the ListBox styles from the Standard theme? I
looked in the generated CSS file but the ListBox style is empty.

Thanks,

Re: 10 MB increase of the size of the web app directory with the generated JS files

2011-10-12 Thread Thomas Broyer

Check the WEB-INF/deploy subfolder. If you don't care about remote logging 
(client sending logs to server) and stack-trace deobfuscation, you can 
safely delete it altogether.

...and you can pass the -deploy option to the compiler to output the files 
elsewhere.

GWT HTML5 Audio - problem changing src midstream

2011-10-12 Thread Chris

When I attempt to change the source file destination of the
underlying Audio object, nothing happens; in fact, the controls
actually disappear.

In order to change the source, I am listening for an event on our
EventBus.

When I receive a new source file, I do the following:

audio.setSrc(sourceUrl);
audio.load(); // to reset the audio object
audio.play();

The source URL is valid, but the Audio player doesn't seem to be able
to handle this use case.

Has anyone ran into this as well?

Thanks.

fileupload does not work with files larger than around 15kb: ACCESS DENIED!

2011-10-12 Thread m...@grayout.de

Hi all,

I am currently working on an gwt application where the client needs to
upload some files on the server so they can undergo some further
processing.

I found the Servlet shown below in some Tutorial that, invoked by the
client, should allow me to upload a file to the server. Interestingly,
this works for small files (text and binary) a far as they are not
larger than something around 15 kb.

Otherwise, I get an error looking like this: access denied
(java.io.FilePermission /var/folders/iw/iwDgjwOcEVqjzDb6t18ytnj1v9w/-
Tmp-/upload_78b21457_132f972f394__8000_0010.tmp write)

Help would be much apreciated! Thanks in advance!

Best Regards,

Uli

PS: And here comes the code:

public class FileUploadServlet extends HttpServlet implements Servlet
{

  private static final long serialVersionUID = 8305367618713715640L;

  protected void doPost(HttpServletRequest request,
HttpServletResponse response)
  throws ServletException, IOException {
response.setContentType(text/plain);

FileItem uploadItem = getFileItem(request);
if (uploadItem == null) {
  response.getWriter().write(NO-SCRIPT-DATA);
  return;
}

byte[] fileContents = uploadItem.get();
//TODO: add code to process file contents here. We will just
printit.
System.out.println(new String(fileContents));
response.getWriter().write(new String(fileContents));
  }

  private FileItem getFileItem(HttpServletRequest request) {
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);

try {
System.out.println(request);
  List items = upload.parseRequest(request);

Places - How to customize the place name? And what's the best way to use AP with Gin?

2011-10-12 Thread benneq

Hi,

I've now completely moved to Activities and Places. Works quite nice.
But now I want to make things look more pretty and a bit more
efficient.

Short about the website: It's a pretty simple Homepage. That means: We
have a menu (for changing places). And a content panel that switches
its activity when the place changes. Nothing special...

The first thing is: In my URL bar there's always the class name of the
place. I think it must be possible to use a custom name?! How can I do
this?

Second: Google says that we should make our Activities a Singleton,
'cause DOM Manipulation is bad ;) I've done that. My app still works
perferctly. Now I want to know if I could make Place a Singleton, too?
A place is a really small object, I know. But why should I recreate
it, if I don't have to?! So, are there any disadvantages saying Gin to
take my Place as Singleton?


(Third question: What do you think is the best way of dealing with
Activities and Places together with MVP? Actually I just moved my
Presenter Code into the Activity classes. Is there anything bad about
it?)

Thanks :)

Re: Full page in GWT or just parts?

@Uemit
you can write one module to be used in all pages and use code
splitting feature to download only what is needed by the particular
page.
i do that this way.
another habit i worked out over years using gwt is to use onModuleLoad
method only to register js callbacks. how does the module behave on
particular page is then scripted in javascript. however i had to
slightly enhance bootstraping script :).
generally my pattern is to write whole client logic with gwt (using
code splitting and merging modules as much as possible) an then
slighlty script it on page to customize its behaviour.

Re: Places - How to customize the place name? And what's the best way to use AP with Gin?

2011-10-12 Thread Jens

Hi,

1.) The url hash fragment (everything after #) is by default defined as 
prefix:token. The prefix can be changed by using the @Prefix annotation 
on your PlaceTokenizers. If you do not use the @Prefix annotation the places 
class name will be used by default (thats what you currently have). Keep in 
mind that the names you provide with the help of the @Prefix annotation must 
be unique.

2.) You should make your views singleton as they are expensive to construct 
because of DOM operations. An activity is a pretty lightweight class you its 
fine if you recreate it. But of course you could make them also singleton.

3.) I think places can't be singletons but I am not quite sure about it. My 
first thought ist that PlaceController stores the current place and when you 
call PlaceController.goTo(newPlace) the new place will be compared to the 
current one using equals(). If they are equal nothing will happen.
If you have singletons and you switch between totally different places 
everything will be fine but if you want to switch between same places with 
different internal states you got a problem because they will always be 
equal. For each place you only have one singleton instance thus you only 
have one state. You can't have a current state and a new state for the same 
place instance (e.g. you are at PlaceA(null) and you want to switch to 
PlaceA(stateValue)).
Places are pretty small and easy classes, so just create new ones as you 
need them.

Re: Places - How to customize the place name? And what's the best way to use AP with Gin?

2011-10-12 Thread benneq

Thanks for your reply :)

Yeah sure, my Views are already Singleton (maybe someone could tell me
what's the difference using Gin @Singleton or .in(Singleton.class) ?!)
And my Presenters/Activities are Singleton, too.

After reading your thoughts, I'd say, that my Places could be
Singleton, too. 'Cause my menu doesn't allow switching from Place A to
Place A, but they're so small. I think I'll leave them as separate
Objects 'til someone says that it's safe in all cases.


Can you tell me 'how' to use these Place tokens? Are they meant to be
some kind of variables? (like x.html?var=value)? If that's true, I
hope that Google implemented some methods to easily safe and restore
variables and values...

Convert Java bean Object to JSON in GWT 2.4

2011-10-12 Thread GereMora

Hi Guys!,

I'm working in a Project with GWT 2.4 + Smart GWT 2.5. I need convert
my Java beans in JSON string.
I tried with some library without success (gwtprojsonserializer,
gwtjsonizer and the AutoBean framework of GWT).

Anyone know of a library that works for this?.. Let me know!.

Thanks!.

Gere.

Unable to suppress header sorting in DataGrid using GWT 2.4

2011-10-12 Thread Adam

I am trying to add a button to a DataGrid header by extending Header
and I've been able to do that and detect the click event just fine.
My problem is that the underlying AbstractCellTable code is firing
ColumnSortEvents for every click in the header and there is no simple
way to stop that behavior outside of not making that column sortable
or completely overriding AbstractCellTable#onBrowserEvent2, neither of
which I want to do.  Has anyone else ran into this issue?

Thanks,

Re: Convert Java bean Object to JSON in GWT 2.4

As to JSON:
Have you tried Google GSON library ? http://code.google.com/p/google-gson/

And second question:
Do you really need JSON?
RequestFactory does not suit your case?

Re: Places - How to customize the place name? And what's the best way to use AP with Gin?

2011-10-12 Thread Jens

While the prefix identifies the place, the token stores the internal state 
of that place. 

How to convert a place state into a string token is up to the developer by 
implementing the getToken() method of PlaceTokenizer. If a MyPlace has two 
state variables s1 and s2 you could create tokens like #MyPlace:s1=1s2=test 
or #MyPlace:s1:1,s2:test ... (its really up to you). With some more complex 
customization you can also achieve hash fragments like #/myplace/1/test 
which look more like a typical url (a good example would be the current URL 
in your browser as the new Google Groups website is done with GWT).

Well and the reverse way is also up to the developer. If someone visits your 
site via www.domain.com/#MyPlace:s1=1s2=test you have to create a place 
based on the token (thats done in PlaceTokenizer.getPlace()). So you would 
split the token into its parts and construct a place new MyPlace(1, test). 
The Activity could then use the state information 1 and test to 
configure the view or to preselect something, etc.

So basically its somehow like URL parameters but its much more customizable 
as everything happens inside the hash fragment of the URL.

Re: Adding external jar to client side

to include external gwt library in jar:

1. library jar should have gwt.xml inside it with arbitrary name
identyfing the lib. for example
file named YourLibrary.gwt.xml with contents as below:
module
   inherits name='com.google.gwt.user.User'/
/module

2. gwt.xml file in project that uses it should inherit it with:
inherits name=your.jndi.path.package.YourLibrary/ !-- note the
name is the same as gwt.xml in jar and package the jndi path to where
it exists --

3. make sure your has the library jar in classpath (in eclipse set it
in porject properties or pass it to javac when compiling).

it should work ;)

Thoughts on Adding Widgets

2011-10-12 Thread gangurg gangurg

Posted  a similar question before but could not get any  concrete answer for
this . Now the problem is back to haunt me  again .  Would appreciate any
help on this , especially with 2.4 GWT APi avilaible , just want to check
back with you guys If this is even possible .

Basically what I want to do is replace  the text typed by a user with
Widgets .  Think of it as a Rich text area where atomically a word if spelt
wrong we get suggestions on the word  and the word gets replaced with the
right one . I want to do something except that the word should get replaced
with a Widget ( which can be vertical , horizontal Panel etc) . I don't have
to implement this in  a text area , i could do this  in any widget .
Thinking of Flow Panel to implement this but my thoughts do not cross
anywhere beyond the flow Panel .

Suggestion Team ?

Re: PlaceHistoryHandler for URL with multiple args

Hi Thomas,

Thanks for putting this, but how do u register the tokens specific can you
given up a n entire example along with Activities and
Place

eg: http://localhost:/book:id=1id=2
http://localhost/search?author:name=50publisher=MIThttp://localhost/author:name=50publish=MIT


Meaning in the above the example you suggested how to parse the token, but
how do you register this token for each place.

how to achieve different parameters for each of the place, pls suggest ur
thoughts, Thanks in advance
Sri.

Re: PlaceHistoryHandler for URL with multiple args

Not exactly sure what you are looking for but I think you want to look at 
the PlaceHistoryMapper:


public class AppPlaceHistoryMapper implements PlaceHistoryMapper{

public Place getPlace(String token) {
if(token.startsWith(something)){
//assume SomethingPlace has params
//so the token is actually something?p1=2p2=12
//this would just route anything starting with something
//to the SomethingPlace
//the constructor should handle parsing the actual param values
return new SomethingPlace(token);
}else if(token.startsWith(something-else)){
return new SomethingElsePlace(token);
}
return null;
}

public String getToken(Place place) {
if(place instanceof AppPlace){
return ((AppPlace)place).getToken();
}
return null;
}
}

Re: Server Side serial port access in GWT with RXTX

Remove any appengine jars from your app since you won't be needing
anything from that for this.  And if you're using eclipse or something
like that to build/run it, remove it from your project there too.

Does whatever user you're running your web app in have write access to

All your places can extend this class and you can use 2 constructors 
depending upon the context:

   1. Use this if you are constructing the place, to be used with 
   placecontroller.
   2. Use this for constructing place within PlaceTokenizer.

And when ever you want a param, just call place.hasParam() and 
place.getParam()

Hope this helps.

Re: rss feed

2011-10-12 Thread Alvin Reyes

Hi, what portlet api are you using?

if I may, I think you need the XSD and the rss feed link so that you may be
able to parse data from your portlet.

I suggest you create first your parser api (or you can search for any parser
via google - theres a lot of open source java api you can use for this) -
this is for you to retrieve data from the RSS feed then use that data in
your own portlet.

[gwt-contrib] Add HasEnabled to SuggestBox (issue1567803)


Thanks for taking this over Stephen. Could you extend SuggestBoxTest to
cover it? Also, have you looked at the behavior manually? Does it
actually work as expected? In particular I'm wondering what happens if
the user tabs into the box.

Actually trying this was a good idea; I made a sample that
enabled/disabled the box every 2 seconds, and if you were in the box
when it was disabled, the suggestion list stayed put. So this fixes
that.

I added a few more elements on the page and tabbed around while it was
both enabled and disabled and didn't see any issues. When disabled, it's
not in the tab order. When re-enabled, it's back in the tab order.

user/src/com/google/gwt/core/client/JavaScriptException.java:191:
description = description + :  + getDescription(e);
Description now defaults to , and a manual description can be passed
in to the constructor. getDescription(Object) is a static method that
gets info out of an exception or one or two other kinds of objects. The
init call here ensures that we see both the optional description and the
summary of e.

I'll doc it, or rename the static method to clear things up.

[gwt-contrib] Include non-client side types in dependencies (issue1569804)


Reviewers: zundel,

Message:
This is just a spike, but client-side code now gets successfully
recompiled if its binary-only annotations go-away/appear/change.

A few notes:

All of the getResourceAsStream calls (especially for the made up
simple/qualified refs that come out of JDT) took up a lot of time if
done repeatedly, so I had to introduce a Ref cache so only look them up
once.

Should probably only get the context class loader once as well.

Was thinking it might be nicer to have a NULL Ref, at least for the ref
cache it would make distinguishing between has not been checked yet
and no ref was found. Right now I do a map.containsKey then another
get.

I can work on polishing this but wanted to get a draft out to see if you
had any comments on the approach.
