Hi,

Glad you found a way to go. I was disconnected this weekend, so I didn't
see your messages...

I'll take a deeper look at this to avoid TW crash. When I got time :-/

cheers,

[Beckstrom]

after a whole lot of troubleshooting, I think i figured out what was causing 
this weirdness! my server was set to lazy-load all, including tiddlers, and 
that seems to have been messing with this plugin.

I disabled lazy-loading for tiddlers and this is now working great! thanks for 
your help!

[tw5] Re: How to use a field value in a json string?

[Beckstrom]

So I think I spoke too soon... there's something weird going on, strange 
behavior. Here's what happens:

- I create a tiddler with a field called "point" and set the value to 
something like 24,-82
- I save the tiddler
- I can see the map, and there is a marker at the lat/long I specified
- If I close the tiddler and re-open it, it works fine (map appears as 
expected)
- But if I either reload the wiki (from the "reload" button in the sidebar) 
or refresh the page or in any way view that same tiddler again, I get a 
javascript error popup.

It says:

Internal JavaScript Error
Well, this is embarrassing. It is recommended that you restart TiddlyWiki 
by refreshing your browser
TypeError: flds.text is undefined

Looking in the javascript console, I see:

TypeError: flds.text is undefined line 15899 > eval:506:25 
 eval>
mapTiddler $:/plugins/sycom/leaflet/mapWidget.tid:506
mapPlaces $:/plugins/sycom/leaflet/mapWidget.tid:228
execute $:/plugins/sycom/leaflet/mapWidget.tid:188
render $:/plugins/sycom/leaflet/mapWidget.tid:69
renderChildren $:/core/modules/widgets/widget.js:391
render $:/core/modules/widgets/list.js:300
renderChildren $:/core/modules/widgets/widget.js:391
     etc ... ..

Any idea what might be causing this?

[tw5] Re: How to use a field value in a json string?

[TonyM]

Folks a slight diversion.

I am a keen user of what3words which has a three word name for every 3m x 
3m square on earth. One advantage is the location is easy to read, 
available in multiple locations and can be easily shared by voice over the 
phone, with other share options available.

There are API's and mapping available and this would integrate well with 
tiddlywiki and leaflet. Happily each location tiddler can be named with a 
location name eg; guard.cling.radio

https://w3w.co/guard.cling.radio
This 3 word address refers to an exact 3m x 3m location. Tap the link or 
enter the 3 words into the *free what3words app* to find it.

Regards
Tony

[tw5] Re: How to use a field value in a json string?

[Beckstrom]

Aha, thank you so much for the reply! I'm not sure what happened but this 
*seems* to be working now after a reinstall of the plugin. I think I maybe 
messed up the original view template.

At any rate, this seems to be working for my wiki now. Thanks for your 
help, and for creating such a cool plugin!

[tw5] Re: How to use a field value in a json string?

[Sycom]

Hi Beckstrom,

if your tiddler is actually a geoTiddler (i.e. it has at least one point(s), 
line(s), polygon(s), place or geojson field) it should automatically 
display a map at the bottom of the tiddler.

This behaviour is defined through the 
$:/plugins/sycom/leaflet/templates/geoTiddler tiddler. You may edit this 
one to modify default appearance of the map or disable it.

I'm not sure how your wiki works or what you want to do. If you have 
geoTiddlers you can map them directly :

<$leafmap places='{"tiddler":"Belgium"}' />


or through a filter

<$leafmap places='{"filter":"[tag[country]tag[Europe]]"}' />


Due to leaflet map widget syntax, I'm afraid that "dynamic call" should be 
made through macros you will have to define locally or globally (see 
https://tiddlywiki.com/#Macro%20Definitions%20in%20WikiText). Very unsure 
about your success with this strategy since the plugin was not designed for 
this...

If this is not the behaviour you expected, feel free to share (a part of) 
your wiki and describe what you want to achieve. I have not much time now 
since I just started a new job, but I will try to help you asap.

cheers,

Sylvain
