Hi guys. I'm tryng to change somthing in my app, but the companion doesn't work anymore if the app contains the tableviewer extension (i have the V4 installed).
Can some one help me ?
Is your companion the newest version? and if other extension working? newest version of this extension?
I have re-installed the companion yesterday .
I made a new project jast wiht 1 button e no blocks.
Tableviewer V4 loaded on extension.
connected the companion and picture is the results
We are now on version 8
I know, but i worte 3 huge apps whit the V4. and i need to make only a little change.
V4 has not the show table so i need to change a lot of blocks (10 screen every app with tableview for every screen). So i only want to figure out if the problem is mine o i need to update everything. thanks in advance
Oh, that app 
Yes i'm not new to this topic. A company of about 230 deployees use those apps.
I don't know, if i make a new app with tableview V4 it works, if i use an old app with V4 it does't work... this is an old one and i removed the estension and the problem is still there.

If testing with companion app, try clearing out all your assets in the companion app on your device.
I clean all the assets but no results. I lunch companion whit V4 and no screen on the phone is visible, then i update the extension to V8 an magically the sceen shows the app without reconnect the companion. So i think is necessary to update all.
Ok i clear all the folder \edu.mit.appinventor.aicompanion3 and reinstalled the companion and everything goes fine. The V4 works too.
Sorry for the waste of time. tanks

Hi All,
Here I am again, with a question: How to show an image within a TIMAI2' TableViewer? I mean, how to show an image converted this way:
which is saved in a SQLite table. The field in table is TEXT.
Thanks in advance,

It is not my Tableviewer, it is @Kevinkun s.
-
Can you confirm the value coming out of your sqlite database is a base64 string of an image ?
-
The method for displaying images in Tableviewer is documented here:
[FREE] TableViewer - fully style customized to show table data - #59 by TIMAI2 -
Not tested but it should be possible to construct a datauri to display the base64string without having to convert it back to a file.
-
Do you know the mimetype/filetype of the image in the base64 String (e.g. gif/jpg/png/webp) ?
Had a chance for a quick test on this, unfortunately, not working....
Example datauri for a green square

Image datauris work ok in a webviewer, so you could use a dynamic html table instead.
Meanwhile @Kevinkun might be able to fix this ?
[EDIT - aah - spotted the problem, will hopefully fix and report back soon]
Not a tableviewer issue at all (apologies @Kevinkun), but a bug in the list from csv table block (incorrect handling of single quotes and commas inside them). You have to directly build a table:

It looks like you are trying to reshape a table row by row, but you aren't accumulating the new rows in a fresh table.
By the way, there is a new advanced list block to wrap that kind of transformation.

You are not making a list of lists, which is required.

Ah ok, thanks!!
Yes, that's right!! I had to do this row by row because of two fields that I need to show as an image, as you can see in my blocks.
Great. Where do I find this?
