Pattern throws an error

Bug Reports / Issues

After extensive work on a pattern I closed it and went to bed. (yesterday) Today I first updated to 2024.11.11.202 (Win 11) Then opened said file to finish it, but opening it throws an error. line 451 column 17 On this line stands: groups (with signs that go missing when message is posted) I then tried nearly all my other files and none had the same error, so presumably it wasn’t the update that caused it. Attached file for perusal. 1775 coat.sm2d (57.9 KB)

Hello, @DraftCraft

For some reason your pattern doesn’t like the provision for groups, so I’ve deleted it and now your pattern works.

Perhaps @Douglas or @Pneumarian should have a look because I have no idea why.

Thank you very much Grace. I did try erasing that line, but it returned after reopening. Your version however does work, curious what I might have done differently. But thanks for the quick response

It will return because it’s the provision for if you wish to add groups. I’d suggest that you create a group with anything in it. Perhaps that will permanently fix the problem.

However I do suggest that @douglas have a look. It may be a bug that’s snuck into the software.

Since files without images have <groups/> between </pieces> & </draftBlock> I tried moving <groups/> to between </pieces> & <images> instead of between </images> & </draftBlock>, & that seems to have worked as well, so I wonder if this is related to @Onetchou’s work.

That seems to be the issue… And I know what it is. When a new pattern is created all the (empty) element tags for a draftblock are created to establish the order of the tags. Except - the TagGroups was not included… which before adding the images was not a problem as the TagGroups was just appended whenever a Group was created. But now with the TagImages - which also just gets appended, means if you load an image first, then create a group the order gets mixed up and when the file is parsed it throws a file excpetion.

It’s a side effect of who ever added the groups feature - they didn’t have the basepoint tool create the TagGroups… and subsequently the tagTagDraftImages. It’s simple fix. Already done.

@DraftCraft

Moving the < groups > before the < images > will fix the problem… in this pattern. Until I make a PR for the fix, the way to avoid the issue for now with any new pattern draft blocks is to create at least 1 group first before loading any images.

I just made a build and created a new pattern to check… it’s now writing an empty draft block correctly. :slight_smile:

<draftBlock name="Draft block 1">
    <calculation>
        <point id="1" mx="0.0520833" my="0.104167" name="A" showPointName="true" type="single" x="0.3125" y="0.416667"/>
    </calculation>
    <modeling/>
    <pieces/>
    <groups/>
    <images/>
</draftBlock>
