Re: elemental2 indexeddb example?
Thanks, I did make some progress. I dug around a little in the javadoc
and found the IndexedDbGlobal, which I was able to use to create a new
database.
elemental2.indexeddb.IDBFactory indexedDB =
elemental2.indexeddb.IndexedDbGlobal.indexedDB;
elemental2.indexeddb.IDBOpenDBRequest openDBRequest = indexedDB.open(
"mydbtest", 1.0);
So far so good.
With a open database call, I get a returned object of
elemental2.indexeddb.IDBOpenDBRequest
(https://static.javadoc.io/com.google.elemental2/elemental2-indexeddb/1.0.0-RC1/elemental2/indexeddb/IDBOpenDBRequest.html)
In the google documentation that I have found that describes the indexedDB
open
operation,
https://developers.google.com/web/ilt/pwa/working-with-indexeddb#opening_a_database
They provide the following code:
var dbPromise = idb.open('test-db2', 1, function(upgradeDb) {
console.log('making a new object store');
if (!upgradeDb.objectStoreNames.contains('firstOS')) {
upgradeDb.createObjectStore('firstOS');
}
});
I want to register a function to execute when the database is upgraded. I
see there is a openDBRequest.onupgradeneeded(), but I just can't the syntax
right.
elemental2.indexeddb.IDBFactory indexedDB =
elemental2.indexeddb.IndexedDbGlobal.indexedDB;
elemental2.indexeddb.IDBOpenDBRequest openDBRequest = indexedDB.open(
"mydbtest", 1.0);
//how to i call a function for upgrade? I want to create some object
stores.
openDBRequest. onupgradeneeded = doUpgrade();
Thanks for your help.

GWT application implemented as Wordpress plugin
All, Just wanted to announce that after learning some other web technologies, it's nice to come back to GWT. I feel so much more productive. That said, I have released a Word Press plugin that uses a GWT application for the user interface. It's open source, and uses the Wordpress REST Api and security. It may be a good starting point for someone if they wanted to implement a wordpress plugin with GWT. https://github.com/rhodebump/forgebiz-closings https://wordpress.org/plugins/forgebiz-closings/ Sincerely, Phillip -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

Googlebot dissing my GWT app
Hi, I have been trying for weeks, but can't get google to update it's index for my GWT application. If i do a google search of my site (site:www.spotmouth.com), only my first page comes up. I have read (many many times) the docs for https://developers.google.com/webmasters/ajax-crawling/ To summarize, I followed the steps: 1) Updated my site to use the ajax crawlable link format (i.e. http://www.spotmouth.com/#menu -> http://www.spotmouth.com/#!menu) 2) Implemented htmunit on serverside so that server responds with static copy: http://www.spotmouth.com/?_escaped_fragment_=menu 3) updated http://www.spotmouth.com/sitemap.xml to use ajax crawable links. (ie http://www.spotmouth.com/#!menu) But if i do a google search of my site (site:www.spotmouth.com), only my first page comes up. Nothing else. I will literally ship a case of beer to whoever helps me fix this (if your state allows it, and I can get it delivered). If I use the "Fetch as googlebot" tool in webmaster tools for " http://www.spotmouth.com/#!menu";, it looks good, that is, a static copy of the content is returned.

writing gwt application to be able to use wordpress/drupal themes?
Hi, I have a GWT application that many consider to be ugly (which is my fault since I am not a designer). One idea that under consideration is the writing of some GWT components, such as "Page", "Article", "Footer", etc... that use UIBinder and emit html that would match what a product like wordpress or drupal emits. If I do this, any wordpress/drupal theme would be usable for my application. By putting my widgets inside these different types of objects, I could have my GWT application look pretty;) Any thoughts?

Long Polling (aka server push) with JsonpRequestBuilder?
Hi, I am trying to implement server push using the idea described here, http://code.google.com/p/google-web-toolkit-incubator/wiki/ServerPushFAQ While I have read that one must keep the outbound connection down to two, I cannot seem to be able to have two simultaneous requests from JsonpRequestBuilder succeed. I use httpfox, and both requests return successfully with their json data, but GWT will throw a SocketTImeoutException for the 2nd request. The same request is successful if there I am not doing my "polling" in another request. Here's the step process: 1) Make a request #1 using JsonpRequestBuilder. The server "waits". 2) Make a request #2 JsonpRequestBuilder. The server responds (according to httpfox) successfully. 3) GWT reports a com.google.gwt.jsonp.client.TimeoutException for the request #2 4) Request #1 completes successfully (both httpfox and GWT) Any thoughts?

Form vs. chunk data to send via JsonpRequestBuilder
hi, I need to transfer a image file (which is a url encoded string) to a third party server. GWT has a reference to this string (wrote a library that integrates GWT with Phonegap). As I see it, I have 2 options: 1) Use the GWT form and put my image string as a hidden form field and post it to the server. I would use a second JsonpRequestBuilder to get the results using some common key in the requests. or 2) Split the string up into chunks of 2000 characters, send each chunk using it's own JsonpRequestBuilder and reassemble the complete file on the server. Or is there a third option? Thanks! -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

GWT/iphone/phonegap server communication
All, I am building an iphone app using GWT/phonegap, so my GWT application will be running from the filesystem in Safari. Given this, would it make sense for me to use RPC to communicate with remote server? My assumption here is that running from the filesystem will allow me to do this. I have been going down the road with JsonpRequestBuilder, but as I think about it, am I making things harder for myself using JsonpRequestBuilder when I could be using RPC? Any thoughts?

Re: Using Javascript Overlays vs. Manually setting up POJO instances?
I did some reading up on RPC. Sounds like it would be perfect except for the face that it is limited by the Same Origin Policy, so I can't use it. I wish we could do an RPC with JsonpRequestBuilder Thanks for your insight, you have convinced me to do the Javascript Overlays. I do like type safety and it sounds like it would be more efficient.

Using Javascript Overlays vs. Manually setting up POJO instances?
I have several Java classes that I am using on the serverside, and I am using these same classes to serialize the JSON stream back to my GWT application. I am using the JsonpRequestBuilder to call my service and it is successfully returning a JavascriptObject. What is the recommended approach to getting my objects from the json response?, should it be a) coerce my JavaScriptObject into a string and use the JsonParser, or b) write a 2nd implementation of my classes using Javascript overlays? I don't really like either approach, one option means having 2 types of objects that I would need to keep in sync (the pojo and the Javascript overlay) and the other way means I have to traverse the Json myself, populating my object glyph manually.
