Thingworx Tabs - Collection within tab only shows data on page reload
Thingworx Version: 9.5.2
I'm going to try to be as precise as possible here, so bear with me.
In a Mashup that is exclusively used as a popup window showing our page's software history & changelog on two separate tabs respectively, we've encountered an issue where the data of the changelog isn't loading unless you specifically open the Mashup on the tab the text is supposed to be loaded in - meaning if you load the Mashup on the first tab, then switch to the tab with the changelog, it isn't visible. The data is still there (you can see Mashups created within the collection in the debug view), but it just doesn't show - resizing the browser window also makes it show, but that's unfeasible for practical use.
The Changelog itself is made of two parts, a list and a container with that shows the changelog itself, which is just a collection with mashups that only contain formatted labels. (I've found no better way to do changelogs since we still have no replacement for the HTML formatting removed...).
There's just one service handling everything, it runs on load once and has all the data from the list itself (each version) and then all the text in another infotable that gets fed into the collection from "Selected Row(s)" so I can browse the list items and it'll always show the changelog of whatever version is collected.
This works perfectly fine if the Mashup loads with that tab already open, but if the other tab is selected and you then switch to the Changelog tab, the list is still there and you can select items, but no text shows.
Here's what I tried so far:
- Lazy Loading & Load / Unload with loads happening on Tab Switch
- Refreshing the Mashup on Tab Switch
- Auto Refresh (calling the service again) every second (just for testing to see if it'd do anything)
- .Load All vs. Load / Unload
I appreciate a response of any kind! If screenshots of bindings etc. are required do let me know, but I feel like I tried every combination and approach under the sun at this point... Fearing this might just be a bug of the version.
