newblocks: deleting a web component results in error next time project will be opened about appinventor-sources HOT 4 CLOSED

Hi @puravidaapps thanks again for the report. Does it happen to you 100% of the time? I was able to reproduce it once, but only once... need to find a more consistent way of making it happen. When you say 'rename Web2 by Web1' you mean just switching it in the call block, right?
Do you use the save button at any stage in the process?

from appinventor-sources.

I can reproduce it easily. I simplified the example for you: create a project with 2 buttons and drag a "when Button2.Click" block out in the blocks editor

then switch it in the "when Button2.Click" block to "when Button1.Click"

and click Save, then delete the Button2 component, click Save, open another project and come back, you will get the error [ERROR] Error loading blocks for screen 5559130790035456_Screen1: : Error: "Button2_Click" is an unknown language block. and the block "when Button1.Click" disappeared

Hi Taifun; thanks again. I believe I know what's happening, but it seems to be a race condition. I get it at times, but other times I do not (worst kind of bugs!).
Basically the Blocks Editor and Designer are out of sync for an short amount of time, and if the user loads a different project before they get a chance to get in sync, then the problem happens. We will look into it. Thanks!

fixed and pushed. Thanks!
