Creating cache lib error multiplied

[Piotr Gałka]

In my schematic I have only one element named T68CA.
Having my schematic opened I deleted that element from library.
{Precisely: It was alias. I renamed that alias. I reopened the symbol editor to see the new symbol created with my old alias name. I deleted that new symbol. So there are no that symbol in library.}
I closed the symbol editor and returned to schematic.
I closed schematic - nothing happened.
I opened schematic. It wonted to (I'm not sure words used here) rescue that symbol.
I canceled it.
When I wonted to save schematic I got an error - Error1.png and it is OK.
I pressed [See details >>] button and I got Error2.png.

I think there should be only one error and not the probably endless list.

Was the T68CA element in a hierarchical sheet? Can you upload an example project showing this?

[Piotr Gałka (piotrgalka)]

It is one sheet schematic.
I noticed it with other symbol (it happened as I am manipulating in my libraries) then repeated it with that one to make screenshoots, and can write that I have only one such symbol at schematic and not as lot as errors in Details window.
I suppose it will be the same with any symbol.
I also suppose that it is not important that I had that symbol defined as alias - I will check.
I can't upload that schematic. I will do the schematic with one element only and if it will work the same (as I suppose) I will upload it.

[Piotr Gałka (piotrgalka)]

I was wrong.
When I tried it with schematic with one element only I get Detailed list with one Error.
When I tried with one element, but alias (as previously) I also get only one error in detailed list.
It is not as simple as I supposed.
Will try to find 'working example', but later (just got something to be done immediately).

[Piotr Gałka (piotrgalka)]

Select that project.
Open schematic.
In rescue helper press [OK].
Press Save toolbar button.
In Error press [See details]

I get a list of 4 the same errors. As I reduced the schematic the list length reduced. It looks that you get as many errors as you have symbols at schematic.

[Wayne Stambaugh (stambaughw)]

It would be fairly easy to not add duplicate errors in the message box. I'm assuming this is the bug you are reporting and not the fact that you deleted the symbols so that they could not be saved in the cache file. If it's something else than please define exactly what you want fixed.

[Piotr Gałka (piotrgalka)]

Yes. I'm reporting only the error duplication in that one window.

[Wayne Stambaugh (stambaughw)]

I pushed a fix for the duplicate missing symbols error but there is also still the potential for enough missing symbols to cause the message dialog to become too tall for the display so I'm going fix that as well.
