Re: Generated Maven pom.xml does not add GWT project natures

Just curious ... can't you just right click on the pom.xml and then
select Run As and use gwt:run as the goal?

Re: Found an inconsistent behaviour in GWT Expenses Roo application: Master-Detail Activities-Places becoming out of Sync !

1- so all the effort that goes into creating a Bookmarkable and Navigable Master/Detail Activity goes to waste ?

Er, why?

It's a) an implementation choice (dictated by "ease of implementation" here) and b) it would be no different using something else than activities.

(that being said, I doing quite like master/detail views when it comes to web apps)

2- what is the point of using Activity/Places to create this Master/Detail scenario, if it is not going to function properly ?

It depends on your definition of "properly", and is not tied to the use of Activity/Places AFAICT.

(the Expenses sample does it some way, there are alternatives, and probably one would fit your requirements, provided they are clearly defined and, to begin with, feasible)

3- can you think of a User Experience that says it is ok for Master/Detail activities to be out of sync ?

Well, actually, yes: as soon as you go to the "next page" while some item is displayed they are "out of sync", so why should we expect it to rollback to "some specific page" when going back to a previously seen item?

(but as I said, I don't quite like master/detail views, they don't work well with on the web IMO; and o course they don't work well with paging; at least something like "continuous scrolling", à la Google Reader, "new" Google Groups, or Twitter, would work much better)

4- do you think end-users, management, or non-gwt developers would consider this an acceptable implementation ?

Probably not, but if it wasn't part of their requirements then they are at fault, not you, so you can sleep in peace ;-)

can something be done to fix this ? some workable solution ? : (

As I was writing the above, it came to my mind that the issue is paging. Remove paging, replace it with "continuous scrolling" (which can be implemented with a Pager too,and I'm sure the GWT team provided some sample code somewhere) and it all goes much better !

(not necessarily without issue, but less issues at least, as you wouldn't "forget" about items when changing pages)

GWT Support Options and Quality

I'm investigating GWT to modernize application development stack for a
Fortune 200 company.

I wonder if anyone on here using GWT for mission-critical core
application? and how statisfied are you with this model of forum
support? What if there is a critical production issue with an
application?

I like the GWT technology, the architecture, and the MVP framework
with Event Bus etc... but I wonder what are the options out there to
receive Enterprise support and have a close relationship with a Google
GWT expert. Or how do you feel about revceving defenitive/expert
answers in a timely manner using this forum other ways of support?

Re: paging in trees

I would also like to know the answer to this.

Re: Multiple entry points in a single project

could you please explain what is the rationale behind using multiple entry points ?
what is the benefit of using them ? and how it relates to code-splitting and gin-modules ?
Thank You

Re: Run method after GWT compiling

Hi all,
Pls help me with the following 2 problems.

I generating the objects with generator. inside generator I need save generated class name to global property.
After last generator was finish, I need save all this classNames to custom file.

So,
1) How can I use some global property to save classNames, or how I can get all generated classNames.

Add an artifact to the generator context; use your own Artifact subtype.

2) How can I detect when is last class generated, or how can I run some method after GWT compiling.

Use a linker. Linker's are run after a permutation is compiled, and after all permutations have been compiled. From the linker, you can find() your generated artifacts in the ArtifactSet using your Artifact subtype's Class.

Re: SEVERE: The Cell Widget is attempting to render itself within the render loop

I am getting this exception more and more now.
I am not using a Date type,
but I manipulate the "range" the table is showing using table.setVisibleRange.
My problem is that I don't understand what exactly is that I am doing wrong,
and how to change my code to avoid this exception.
in other words, what is this Exception "Really" saying ?
if it has to do with Range, under what circumstances this exception occur
so that I can guard against it.

Thank You
