Re: Performance Differences IE 8 Vs FF 3.x
Screen also has real estate issue - I dont think I can use CellList
but its good suggestion John ! I was thinking -- instead of fetching
all the data and setting into suggestion box (oracle etc..) - fetch
the data by making RPC calls when user enters few characters of data
and set it into suggestion box but it could make application chatty !

Thomas - is it due rendering engine of IE 8 versus that of FF or

Performance Differences IE 8 Vs FF 3.x
I have one particular use case when there is significant difference in terms of response time between IE8 Vs FF 3.x IE 8 = 25-35 seconds response time FF 3.x = 5 - 8 seconds response time. Rest of the application seems to be OK in IE 8. In this particular use case, I am making 1 RPC which in data access layer makes 5 database calls and returns the data to java class that corresponds to ui.xml Java class then populates the data returned into 4 list boxes and 1 suggestion box- there is no additional processing of data other than getting it from data access layer. The data is returned from data access layer pretty fast In terms of data, 1 list box has 4000 elements and one suggestion box has 7000 elements. Event to above use case is selection of row from cell table and clicking on edit button - this performs very well in FF and Chrome but has slower performance in IE 8 Any pointers why this could be happen ?

Re: How to handle application state ?
Jeff, I agree on creating a share object and storing into HashMap on client side. But how do I share this HashMap on client side among different screens such as Header, Navigation etc. (Other than passing HashMap to these screens via some setter methods) Mittal On Dec 6, 11:23 am, Jeff Schwartz wrote: > You shouldn't have to query for the information more than once but you do > need to store it some place and like I said, you have several options.

Re: How to handle application state ?
Yes, its application state for a "User". Why do I need to query server information every time for a user, I think I should able to create client side object such as UserProfile, populate it from server side once user logs in and then pass client side UserProfile object where its required such as Header or Navigation pages. - Mittal On Dec 6, 9:47 am, Jeff Schwartz wrote: > In your case the state you want to preserve seems to be associated with a > particular user, not the application, so you can use either cookies or > servlet session state to persist the information when the user logs in and > you can then query the information when displaying tabs or reacting to other > user interface events. > > Jeff > > > > On Mon, Dec 6, 2010 at 9:39 AM, Mittal wrote: > > Here's the use case we are dealing with, > > > SSO token shall be received by GWT application. > > SSO token shall have user profile and role information. > > Once I have read SSO token, I would like to use User Profile > > information to be available in header page and Role information in > > navigation page to control who see's what in terms of functionality > > (tabs). > > > How do I store or hold token information as an application state ? > > > - Mittal > > > -- > > You received this message because you are subscribed to the Google Groups > > "Google Web Toolkit" group. > > To post to this group, send email to google-web-tool...@googlegroups.com. > > To unsubscribe from this group, send email to > > google-web-toolkit+unsubscr...@googlegroups.com > > . > > For more options, visit this group at > >http://groups.google.com/group/google-web-toolkit?hl=en. > > -- > *Jeff Schwartz* -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

How to handle application state ?
Here's the use case we are dealing with, SSO token shall be received by GWT application. SSO token shall have user profile and role information. Once I have read SSO token, I would like to use User Profile information to be available in header page and Role information in navigation page to control who see's what in terms of functionality (tabs). How do I store or hold token information as an application state ? - Mittal -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

CellTable and multiple editable columns
I am using CellTable with simple pager to show ArrayList contacts. There are multiple columns that are editable mostly using EditTextCell. I have implemented FieldUpdater for editable columns. But I do not want to make server side save/update call each time there is change made to particular editable column. I would like to collect all the updates, lets say in ArrayList modifiedContacts and send it server side by using some kind of Save Contacts button. I am able to do this if I keep only one column editable, but moment I add multiple columns as editable, I start getting duplicate objects in my ArrayList modifiedContacts since each editable column is implementing FieldUpdater. When 2 or more columns of same row are updated, FieldUpdater of each column is fired, storing duplicate objects in ArrayList modifiedContacts. I could use Set instead of ArrayList to store unique contact objects but is there better way to do this ?
