so just to clarify, you have a tree in which a node is a name of client-side class....my approach has been to create an xsd, from the xsd generate with jaxb the classes and send it as xml to the client where i show the content of the server side instance as a tree....after modifying the tree content you can send back to the server the tree serialized as xml and always with jaxb insert the xml content to server side classes... i know that in this way client-side classes are missing but who needs? otherwise you can have a tree with a foo root node and as first level childs a set of async tree nodes that when clicked will load the content from the server... i didn't understand why you need a client-side class?? maybe you need to edit the tree content?
after a lot of writing i have a new idea.....try to extend xmltreeloader and working on the load method and on createNode method maybe you can easily obtain the solution.. i recommend a common interface over all the classes with which easily work... bye Pat 2009/8/23 venkat kilaru <[email protected]> > thanks for the response michele. you have given me good idea to store the > data in the xml format which is retrieved in the server side. > > but i have one doubt regarding ivoking the client views dynamically. i.e > we have to store class names as strings. then how can i instantiate the view > java classes. when user click on tree nodes? > > > On 8/21/09, Patrizio De Michele <[email protected]> wrote: >> >> xmltreeloader??? ask for an xml to the server side....this xml must be >> dinamically generated....you can set the url of the xml in the >> treepanel.... >> otherwise you can use json.....that is the native format of the >> treeloader... >> >> for my purposes i have extended xmltreeloader and retrieved the xml from >> the server with an rpc call, and created the tree the way i prefer... >> >> pat. >> >> 2009/8/21 kilaru <[email protected]> >> >>> >>> hi >>> >>> I am very new to GWT and GWT-Ext.
