Hello, I need a functionality to determine the next execution date(s) of a scheduler based on it's cron and last execution date (or date range) but I could not find anything useable in Thingworx or Java. Having this capability I could provide an overview of the scheduled task to the End user.Is there any tool that could help me to achieve this?

In Collection Widget, when number of rows infotable is changing, the cells are expanding and collapsing horizontally. But I want the cells to get expand and collapse both horizontally and vertically.  How to do this?

I am an inexperienced user of Thingworx. We have a pre-existing Mashup which can plot historical data selected using the Date time picker. I would like to change it so that the data is selected based on the Batch Number rather than the date and time (this is a number variable that is already in the data). I am not sure how to do this,

I will trigger service to open particular tab in tab widget. So how to make its tab non clickable physically ? 

Hi, I configured TWX SSO using Okta as IdP.All configurations I believe are correct, I can even login to TWX with SSO, I can open Composer and view mashups. But even though I've given SSOAdmins and SSOUsers (My group mappings in SSO) run time permission for Things, to view, run services, subscribe and etc.When I log in through SSO I can't execute any service and nothing more. It's like the user gets in, but it does not get added to the UserGroups defined.I've also given the UserGroups permissions on PlatformSubsystem, EntityServices.Is there some kind of different way to grant permissions to SSO users?I even tested creating a user and adding this user to my UserGroups, and at runtime everything runs fine, I can execute services and whatnot.I believe the issue is happening when logging in, the logged SSO user is not getting added to the respective userGroup mappings. Thanks!

Good day, all. I hope you are well. I have a filter widget that filters through my stream. I want to take all the data in the stream and export it to csv I am struggling to write a service that does this. This link: https://support.ptc.com/help/thingworx_hc/thingworx_8_hc/en/index.html#page/ThingWorx/Help/Mashup_Builder/Widgets/DataExportWidget.html. Speaks of exporting passwords that are encrypted. It does not address my scenario. Does anyone know how I can achieve this? Many thanks🙂

The New and Improved DGIS Guide to ThingWorx Development Written by Victoria Firewind of the IoT EDC   The classic Developing Great IoT Solutions guide has been reskinned and revamped for newer versions of ThingWorx! The same information on how to build a quality IoT application is now available for versions of ThingWorx 9.1+, and now, a complete sample application is included to demonstrate these ideas.    Find within the attached archive a PDF with high-level overview information on development and application design geared towards managers and business users, so that everyone can understand the necessary requirements, common terms, and key tips on how to ensure an application is scalable and maintainable right from the very start. Reduce your chances of running into issues between PoC and Go Live by reviewing this information today!   Also find within this PDF a series of tutorials which teach not just how to use the ThingWorx software, but which also educate on

Hi Developers,   I had come across a LiveWorx 2017 presentation by Yale Evans describing an effective way to configure Thingworx and Kepware for Dev, QA and Prod servers.    I'm trying to look for the complete video presentation for the ppt but I'm not able to access the content from here:  https://www.liveworx.com/archive The site is showing some internal error   Is the video available anywhere?   Regards, Saran 

i have a problem with the synchronization of thingworx and opc aggregator.first what have i done:use opc aggregator to read out values from machines, use the default settings.in thingworx i connect with remote thing over industrial connections and use for example following settingsi primarily use "read from server cache" or "cached for specific time", it s ok, but here is my problem....i get values by changed, thats correct, but in a few cases the change does not arrive...the setting "fetch form remote every read" would now make sure to always have the current value, but i continue to work with the values in different places and that would trigger too many read operations to opc aggregator here...at the moment my solution is, manually reinitializing the connection in the opc aggregator, in order to force a current query and syncronize opc aggregator and thingworx.is it possible, to query the current value from the opc aggregator, from thingworx?or is there a possibility to trigger the

At time i do reinitialization the runtime of the connections manually.Is there a possibility, to trigger reinitialization the runtime of the connections, from the outside with a service? 

Use the OPC Aggregator to connect to machines via OPC UA to get the signals in Thingworx.Sometimes it is necessary to reinitialize the connection manually, which in my opinion is only possible via the OPC Aggregator. Is there a way to start a service from thingworx that can trigger the new initialization of the OPC Aggregator? If someone from PTC is reading this, is there a chance of getting a feature in the future, new initialization of the OPC Aggregator  from thingworx,  to automate operations? Thanks for help

when i study the example Connect Raspberry Pi to ThingWorx, i encounter this problem: by the way, my thingworx version is 9.1.12-b1048, is this the reason?

In some way, I want to hide the tab header using CSS. When using CSS, it works properly. In my single mashup, I have two tab widgets, and the CSS is applied for two tab widgets.   I want apply below CSS with widget specific.   .widget-ptcstabset::part(tabs-header){ display: none; }   How to apply CSS without affecting more than one tab widget?    Note: Thingworx 9.1

Attached (as PDF) are some steps to quickly get started with the Thingworx MQTT Extension so that you can subscribe / publish topics.

We are aware that conflict serializability is a valid subset of view serializability in  DBMS Schedules of Transactions. However, all serializable schedules may be included in view serializable schedules. A suitable subset of view serializability, maybe, or another option? Has this been examined?

In this post, I show how you can downsample time-series data on server side using the LTTB algorithm.The export comes with a service to setup sample data and a mashup which shows the data with weak to strong downsampling. Motivation:Users displaying time series data on mashups and dashboards (usually by a service using a QueryPropertyHistory-flavor in the background) might request large amounts of data by selecting large date ranges to be visualized, or data being recorded in high resolution.The newer chart widgets in Thingworx can work much better with a higher number of data points to display. Some also provide their own downsampling so only the „necessary“ points are drawn (e.g. no need to paint beyond the screen‘s resolution). See discussion here.However, as this is done in the widgets, this means the data reduction happens on client site, so data is sent over the network only to be discarded.It would be beneficial to reduce the number of points delivered to the client beforeh

Hi, I would like to connect AWS timestream DB using JDBC, Does, Thingworx supports AWS TimestreamDB? I was not able to connect the DB,  The isConnected property of the thing remains false, but I am able to see some logs in the application log. If I try to execute some sample queries, I get the following error:  Unable to Invoke Service test1 on timestreamDB : Transactions are not supported.

HelloRecently I started to use this platform, what I'm trynna do is send a value from a grid advanced to a service or widget, here's how my bindings look like:  The end-user must type an ID which I use as an input for a service (datosprueba), once the end-user presses the enter key it triggers the service and it shows him a table with the required data, that table is editable, like this:  It is expected that the end-user fill in the "cumple" column, like this   This is the part which I'm struggling with, I wanna make use of that "Yes" or "No" value, so I can use it as an input in a service and store it in a database, how can I do that? I'm trynna use the edited table property, but I havent figured out yet how to properly use it, hope I made myself clear, please if any of you can help me. Oh, and btw I already did this:   it just doesnt work, the textfield stays blank. Thanks in advance.
