    Hi nimbusgb,

    One option you could leverage is that in the onItemUpdate callback you cleanup your polygon and associate the new values for points received from Lightstreamer server.
    Something like...

    Hi Dan,

    This message could be considered harmless if sporadic (for your information we are considering to downgrade this log message to info level).

    But please also consider that with the...

    Hi Dan,

    Indeed, I have to confirm that newer adapter libraries could have compatibility constraints and new libraries may not work properly with older server versions.

    Hi nimbusgb,

    Yes, I confirm that DynaGrid can be used to display your svg polygons and let Lightstreamer updates their style properties.

    Hi rperseguini,

    If I understood your scenario correctly you could switch to the COMMAND subscription mode.
    The trick to adopt in your Data Adapter is to consider as "key" field for COMMAND mode...

    Hi nimbusgb,

    Please check if there is always consistency in the field names between the client subscription and the Data Adapter updates pushed.

    Hi nimbusgb,

    I think that in your case you should leverage the COMMAND subscription mode; indeed it was specifically designed to manage dynamic lists or tables.
    Please note that the COMMAND mode...

    Hi Emerson,

    Yes, I confirm that more than one client can subscribe to the same Item and all these will receive the snapshot, upon request, based on the current status of the Item.

    Hi Emerson,

    Paul,

    Yes sure, this is the example in Java https://github.com/Lightstreamer/Lightstreamer-example-Portfolio-adapter-java but there is also for.Net if you prefer.

    Hi Paul,

    Yes you are right, I confirm that the StockList example does not leverage at all the COMMAND mode subscription; sorry for the misunderstanding.
    A good example to refer to for COMMAND...

    Hi Terry,

    Indeed there are potential issues when minifying with proguard an application based on the "full" version of LS Android SDK library.

    Hi Renato,

    1. Sorry but indeed at the moment we have not explicit TLCP examples for command mode.

    Hi Paul,

    First of all sorry for the late reply.

    I can confirm you that the COMMAND mode seems to me the best choice for a scenario like yours. In fact it was specifically designed to manage...

    Hi patrol90,

    No, there are no particular configurations or settings of the environment, your adapters should work fine just at every well established connection with the Lightstreamer server.

    Hi patrol90,

    Sorry, I didn't understood your scenario, so the adapters actually connect fine even the first time but just missed to push updates.
    The second time connected fine as well and also...

    Indeed the issue is quite tricky.
    From the log snippets you attached there is no evidence, in the first case, of connections from you adapters.
    Maybe, the adapters were launched...
