Error after adding a point to an existing Poly Line when re-opening Xlights

[thekameleon]

When I add a point to an existing Poly Line that I have already saved and that has individual segments nodes defined, everything appears to save without an issue.  However, when I close and re-open xlights, I get a dialog box stating that it could not open RGB Effects and my entire layout is wiped clean. (Thanks to how ever implemented the back up feature)
I dug into the RGBEffects.xml filke and found this:

    <model DisplayAs="Poly Line" StringType="RGB Nodes" StartSide="B" Antialias="1" PixelSize="2" Transparency="0" parm1="1" parm3="1" LayoutGroup="Default" Dir="L" name="Roof.Peak.1" IndivSegs="1" Seg5="47" Seg5="53" Seg4="155" Seg3="55" Seg1="41" Seg2="41" parm2="292" NumPoints="5" PointData="0.393333,0.749334,0.411333,0.774222,0.429333,0.799111,0.468178,0.798556,0.540000,0.734222" cPointData="" versionNumber="1" StartChannel="#192.168.1.41:28:1">
      <ControllerConnection/>
    </model>

The Seg5 attribute repeats itself. And looking at the prior saved versions it does not appear to clean up Segments that have been removed. I at one point had 5 segments but I changed it to 3, then added a 4th.  The 4th added point is when the error happens on re-opening xlights as mentioned above.

    <model DisplayAs="Poly Line" StringType="RGB Nodes" StartSide="B" Antialias="1" PixelSize="2" Transparency="0" parm1="1" parm3="1" LayoutGroup="Default" Dir="L" name="Roof.Peak.1" IndivSegs="1" Seg4="53" Seg5="47" Seg1="82" Seg2="55" Seg3="155" parm2="292" NumPoints="4" PointData="0.474667,0.736889,0.500667,0.784889,0.549512,0.786111,0.626000,0.707556" cPointData="" versionNumber="1" StartChannel="#192.168.1.41:28:1">
      <ControllerConnection/>
    </model>

I removed the two Seg5 attributes and so far everything seems ok.

When I first wrote that model you're right I did not bother deleting segments that were deleted and unused because it didn't hurt anything.  My main reason was because I wanted it to retain the pixel size info for each segment if I unchecked the Indiv Segments option and then decide to recheck it again later.  But I thought later Keith added code that does delete them and clean it up.  At this point I wouldn't know how its working without testing.

Ok sounds good. Let me know, what you need from me. (i.e. RGBEffect files, etc..) I found a work around so I am not dead in the water.

What version are you using. Can you record a quick video showing how to reproduce the problem on .46.

I am using 46. I could not reproduce the error by creating a new poly line.  However, if I took the existing poly line and copied into a new RGBEffects file and repeated the steps exactly as shown in the video then you will see the error.

The RGBEffects file and video are attached

Then don’t do that.

Yeah if it can't happen again with a new one then we probably fixed a bug at some point.  We don't go crazy trying to handle all the old errors that might be in files.

I did that just to reconstruct the error for you as you asked.
