Exception falling through catch() in JSNI
I've been toying with Maps Api v3 and markerclusterer and run into a
strange constellation with the following setup:
IE 8 (64 bit) both hosted and production mode, GWT 2.1.1
Markercluster apparently does something to the Map, so that the map
cannot be operated upon immediately when running IE8, i.e.:
1. setup map
2. setup markerclustere
3. zoom map - this throws an exception about a maptype being not
defined
I also get this with Firefox btw. I try{} catch{}'ed this in JSNI
which works in Firefox as expected. But with IE, the exception simply
falls through as if there were no catch statement.
Has anybody seen something similar?

Re: Exception falling through catch() in JSNI
It is probably triggering window.onerror in IE. See gwt-log's setErrorHandler
method in the class below if you'd like to register a handler for it in GWT.

Re: Problem trying to use JSNI to eval() a JSON string
IIRC, eval()-ing a literal object will throw because the braces are seen as opening a block of code, and not an object literal; that's why most uses of eval() for JSON parsing enclose the string within parens. But really, you should use com.google.gwt.core.client.JsonUtils instead, which takes of this for you, and also provides safe parsing using (IIRC) either native JSON.parse or a RegExp check before calling eval(). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

How can I move position of tab headers ?
Hello, I would like to display the tab header more on the right. Currently they are fixed on the left side with a css attribute left that is set to 0. The code that is generated by GWT is the following : div class=gwt-TabLayoutPanelTabs style=left: 0px; right: 0px; bottom: 0px; inside this, there is the code for tabs. /div I thought I could just get the element using code like this : Element element = (Element)nodeToUpdate; and then work on the style or remove it : element.removeAttribute(style); element.addClassName(CssResources.INSTANCE.commonCss().tabsHeader()); or element.getStyle().setLeft(150, Unix.PX) but unfortunately the style is not changed. I could changed some style that was not already set (for instance the color) but the one that are already set, I could not change them. I don't see other path currently.

Re: what cleanup is necessary if a widget creates multiple child elements
If your widgets are adding event handlers to the event bus (SimpleEventBus,
for example) then they would 'probably' need to clean themselves up at some
point by removing the handlers. When they should do this is really specific
to the life-cycle of your widgets. If they are singletons with an
application scope life cycle, for instance (why I used 'probably'), a
reference to the widget will never go out of scope so there is no need to
remove the handlers. If you are attaching, unattaching, and reattaching them
then it would depend on whether the handlers were going to receive events
while they are unattached and what they would do with them. If they update
the dom then that wouldn't work so you would want to clean up the handlers
in this case. But if they were only saving a reference to a list of records
returned from the server for instance then that would be ok and there would
be no need to remove the handler when the widget is detached. I hope you see
where this is going - it all depends on your use case.

With the code above, should I do anything with anotherEl on detatch?
Thanks for the advice.

Re: is there a UiBinder equivalent for ImageResource ?

Re: is there a UiBinder equivalent for ImageResource ?
Yes, there is:
ui:with field='res' type='com.me.client.MyResources' /
The above's type points to your resource budle.
Then:
g:Image resource={res.myimage} /
The above, res is the field name defined in with. myimage is some image
resource defined in you resource bundle. It is now typesafe and checked at
compiler time.

we have this g:Image resource= /
but this is of type Image, not ImageResource.
is it possible to get use ImageResource in UiBinder ?
for example use a variablel in place of resource attribute ?
in ui.xml
g:Image resource=varX/
in .java
@UiField
ImageResource varX;

Re: what cleanup is necessary if a widget creates multiple child elements
BTW handlers can also ignore events while unattached. Lot of choices here.
On Sun, Jan 16, 2011 at 7:18 PM, Jeff Schwartz jefftschwa...@gmail.comwrote:
If your widgets are adding event handlers to the event bus (SimpleEventBus,
for example) then they would 'probably' need to clean themselves up at some
point by removing the handlers. When they should do this is really specific
to the life-cycle of your widgets. If they are singletons with an
application scope life cycle, for instance (why I used 'probably'), a
reference to the widget will never go out of scope so there is no need to
remove the handlers. If you are attaching, unattaching, and reattaching them
then it would depend on whether the handlers were going to receive events
while they are unattached and what they would do with them. If they update
the dom then that wouldn't work so you would want to clean up the handlers
in this case. But if they were only saving a reference to a list of records
returned from the server for instance then that would be ok and there would
be no need to remove the handler when the widget is detached. I hope you see
where this is going - it all depends on your use case.

is it possible to create a custom widget in UiBinder that can contain unknown number of child elements
is it possible to create a custom widget in UiBinder that can contain unknown number of child elements ? similar to FlowPanel and HTMLPanel. for example, how to create a MyContainer, that can contain One or More Hyperlinks ? my:MyContainer g;HyperLink ui:field=a / g;HyperLink ui:field=b / g;HyperLink ui:field=c / g;HyperLink ui:field=n / /my:MyContainer reading the documentation, I noticed there are @UiFactory and @UiConstructor, but I believe they are useful when we have number of attributes. for example my:MyContainer attr1=a attr2=b .. attrN=n/ how can we do similar with child elements ? how can my:MyContainer gain access to its child elements ? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Code Splitting Code Bloat
Has anyone experienced an issue where code splitting has actually increased the size of their application by a significant amount? Before I introduced code splitting my application weighed in at around 109KB. While that' not gigantic considering there is logic for over 10 screens I thought that maybe I could get it down to around 40KB once I introduced code splitting. Once I introduced code splitting the project grew to 429KB! The initial file download is now 181KB. How can this be possible?!! I've looked at the compile report and everything seems to be where it should. Does anyone have any ideas as to why the compiler is inflating the code size by 400%? I know that certain classes may be repeated for each split but the initial shell of the application is now weighing in at 181KB(without incubator grid or any screens) where the entire application (with incubator grid and 10 screens) used to weigh in at only 109KB. BTW, I'm using GWT 2.1.1 and the trunk snapshot of Gin. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

hi Joao, You might want to take a look at the questions posts in the Roo forum (http://forum.springsource.org/forumdisplay.php?f=67) to decide for yourself. But form my limited experience with it so far on my testing project, I would not want to plan on using Roo+GWT on real projects yet.

Re: locale translation
I spent some time on the locale translations.. there are 2 ways which I have seen being adopted. 1. Create a constants class which has its associated property files. The property files can be for each locale 2. If you are using UIBinder you can read up on the Internationalization for UIBinder which differs a bit. This method however has drawn some criticism due to the fact that it is a bit complicated and you can not create a property file for the 'default' locale. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

This allows a single map lookup to determine if a class extends the
