Matlab 2018b, ginput(), and tabbed figures

I have a code set that works in 2017a but does not work in 2018b. I have traced the issue down a problem within the ginput() function when using a tabbed figure (my code works if I eliminate the tabbed figure). The error message that I get is:

Dot indexing is not supported for variables of this type.
Error in ginput>setupFcn (line 221) initialState.toolbarVisible{1} = tb.Visible;
Error in ginput (line 60) initialState = setupFcn(fig);

Here are two simplified versions of the code:

1. Version that doesn't work in 2018b but does in 2017a

a = 1:100; f = figure(100); clf
tabgp = uitabgroup(f, 'Position', [0.05 0.05 0.90 0.90]); tabgp.Units = 'pixels';
tab1 = uitab(tabgp, 'Title', 'Tab 1'); tab1.BackgroundColor = [1.0 1.0 1.0]; tab1.ForegroundColor = [0.3 0.3 0.3];
tab2 = uitab(tabgp, 'Title', 'Tab 2'); tab2.BackgroundColor = [1.0 1.0 1.0]; tab2.ForegroundColor = [0.3 0.3 0.3];
axes('parent', tab1)
subplot(5, 1, 1) plot(a)
subplot(5, 1, 2) plot(a)
[x,y] = ginput()

2. Version that works in both 2018b and 2017a

a = 1:100; f = figure(100); clf
subplot(5, 1, 1) plot(a)
subplot(5, 1, 2) plot(a)
[x,y] = ginput()

Has anyone encountered this? Any fixes?

I ran into this with an axis whose parent is a uipanel and not the base figure. I don't have any workaround. I submitted a bug report to Mathworks, as this has worked for many, many years. Hopefully they will have a workaround.

Here's a simple way to reproduce this bug:

hf = figure;
hp = uipanel;
plot(1:10,rand(1:10));
set(gca,'Parent',hp)
[x,y] = ginput(1)

I just discovered that this bug has been fixed in R2018b update 1. The bug number is 1873881.

I encounter the same problem. I got it work by excluding few of the original lines (SEE THE ATTACHMENT)

It is just a temporary workaround.

I got it work already. It is about case letter, lower and upper case issue.

I kept reading doccument and googling, and I found out that it works on upper case letter in 2017a, but not 2018b. 2018b requires lower case.

I have tested on 2017a and 2018b by using lower case letter, and it works.

Thank you all.

I could not share program and data due to my job type. I hope you got the picture.
