Oracle APEX, 23.1 (though same in 22.2) when including a minimap in an interactive report column,
when more that 15 rows are displayed in the report, the minimaps display, then a second or two later, un-display.
In the console there are a series of this error:
WARNING: Too many active WebGL contexts. Oldest context will be lost.
One for each row that un-displays.
Reading up on the maplibre error, apparently this is a browser limiation, as browsers limit the number of WebGL instances.
It sounds like there are workarounds, but none that make sense for the minimap in a report situation.
Is this a known limitation in the use of minimaps in APEX? or, is there something I can do to/with the minimap settings to be able ot display more than 15 (rows) at a time?
My minimap settings:
<div class="miniMap" id="snorkelMap#WATER_ACTIVITY_ID#"
data-center="[#LONGITUDE#, #LATITUDE#]"
data-zoom="11"
data-marker="true"
data-tooltip="#NAME#-#TIME_NEEDED"
data-interactive="false"
data-attributions="false"
style="width:120px;height:120px;border-radius:10px;">
</div>
Very basic.
I can live with the limitation - I just want to know if there is a workaround, as I am sure others will ask about this.
The image is the report after the maps un-draw themselves.
when the report renders, the maps come in, then, as more than 15 or so minimaps render, the WARNING: Too many active .. errors start and the minimaps un-dra themselves, leaving all the minimaps empty, as shown.
Thoughts, suggesitons, or just plain confirmation that Yup, that's how it works, all welcome.
Thank you,
Karen
