    Hi! I couldn't find any kind of list/gallery of framework font icons. So, I published them here: http://vaadin-icons.herokuapp.com/

    Hi at all :)

    I know this is a vaadin forum. However many java developers might be able to assist me. I want to obfuscate my java jar. I downloaded and run the ProGuard UI.
    I open ProGuard UI and Added input jar and on the final stage i clicked Process! button. Process is completely successfully.
    Where i see the converted, obfuscated jar file? location of the obfuscated jar file?
    2nd question, can i obfuscate the application jar files alone instead of obfuscating rt.jar java file as well?
    I have one jar and need to obfuscate it and struggling with the steps.
    Does anyone can help me with a easy tool which would obfuscate the jar ?

    Is Vaadin good for a client only application (no interaction with a server)?

    v8? no
    can you do it... sure. but why bother

    @ghost~5e5bdb6ed73408ce4fdb3968
    Ok - just asking. Thanks :)

    it depends.. it could be run locally or inside a electron as "fat client"

    @ghost~5e5bdb6ed73408ce4fdb3968
    Electron would work, we've already experimented with Electron.

    @christoph-frick
    you would have to compile your java down to js - the round trips will kill you

    @ghost~5e5bdb6ed73408ce4fdb3968
    ok

    hello, is there any works going to add a Grid#addRow method to v8 or upper? if yes, do we have any Github reference ticket to watch into?
    Knoobie
    @knoobie
    V14 has this epic about Dataprovider in general vaadin/flow#8054
    David B
    @dpbadiola
    thanks. do we know if the epic will be included in the next release v16 or later?

    No idea about back porting atm, @pleku could know more about it. I just read they are actively working on it behind the scene.
    Pekka Hyvönen
    @pleku
    v16 has been feature freeze already and any data provider improvements are still on the drawing board. (so not there)
    v17 seems more likely at the moment and we try to do things in a manner that we can backport everything or most things to 14 minor release.e
    Tatu Lund
    @TatuLund
    We are doing some efforts of keeping Binder and DataProvider implementations between V8 and V14+ somewhat in sync. Like lately I have done some improvements in V8 Binder and pushed them forward in V14+. Likewise, if possible we will cherrypick applicable V14+ DataProvider improvements to V8.
    Knoobie
    @knoobie
    That would dramatically help people with migration from V8 to V14 or even later! Thanks for the effort!
    Pekka Hyvönen
    @pleku
    One issue with the data provider improvements in v14 (or later) is that those would require some changes to the component itself, and because the components are different between v8 and v10+ it is not possible to backport those directly.
    So when I said about being able to backport things, I meant from V17 to v14. So it will probably require further effort for V8 instead of just simply cherry-picking things.
    Knoobie
    @knoobie
    I think nobody would expect you to backport everything to V8 (public LTS ending in 1 1/2 years) - it's more like Tatu did with the Binder; anything that doesn't involve huge refactoring of the commit/codebase could be backported if it doesn't break the framework and helps to migrate later.

    When was @VaadinSessionScope in vaadin8 loaded? Will the front end reload once with a new browser
    Tatu Lund
    @TatuLund

    Will the front end reload once with a new browser

    Front end here is a bit bad term, because @VaadinSessionScope is related to Vaadin server side state. But having said that, the difference between @VaadinSessionScope and @SessionScope is that the first one follows VaadinSession. If you have only one servlet configured in your app, there is only one VaadinSession under HttpSession, so then these are practically the same. But if you have multiple servlets, each one has their own VaadinSession, but they share the same HttpSession when we are operating under the same Browser instance. Did this clarify the situation?

    @admlke
    Thanks for your answers，altDo you know why this is? I didn't find the reason anyway.
    Tatu Lund
    @TatuLund
    Which exact Vaadin version you are using?
    admlke
    @admlke
    vaadin8.1
    Tatu Lund
    @TatuLund
    I would recommend to upgrade to Vaadin 8.11.0, which is the latest version

    I am using a comboBoxMultiselect addon but can't find anywhere a good example on how to add a new element to the list of items and get it selected. Can someone point me out an example or support with a piece of code?
    Christoph Frick
    @christoph-frick
    naive assumption: setting items, then set the value with the new item included?
    Radostin Tsvetanov
    @RadostinTsvetanov_gitlab
    I did try but only the newly inserted element is added and the old ones are removed

    Christoph Frick
    @christoph-frick
    and you can rule out, that _materialList holds all elements right before setItems?
    or rather make sure
    Radostin Tsvetanov
    @RadostinTsvetanov_gitlab
    Sure, it contains them all
    Tatu Lund
    @TatuLund
    I do not know details of this component well as it is not made by Vaadin. But if it follows the same conventions, I would assume that after you set the item selected, you need to call dataProvider.refreshAll(..). If it does not help, this could be also a bug in the mentioned component.

    Knoobie
    @knoobie
    Should this be backported to V8 vaadin/flow#8548 or is the framework not affected by it?
    Tatu Lund
    @TatuLund
    @knoobie , good catch, it possibly should be, I wrote adaptation of it (not just a cherry pick) vaadin/framework#12042
    Knoobie
    @knoobie
    @TatuLund thanks! :)
    Pekka Hyvönen
    @pleku
    Hello. Anyone referring to listing components (like grid, combobox) using the interface type of HasItems or HasDataProvider to set the items to it ? Please comment if you do, thanks.
    Knoobie
    @knoobie
    Only did it for internal addons where I wrote a wrapper for Vaadin components.
    Tatu Lund
    @TatuLund
    @knoobie the PR #12042 was included in Vaadin 8.11.1 released today
    Knoobie
    @knoobie
    @TatuLund Thanks Tatu! Gonna update later
