An error occurs when setting an axes to current axes.

In my Matlab GUI CBIR application, a figure have two axes, whose tag are axes1 and axes2, respectively. The first step, I show a image on axes1. I use the code

ax1 = findobj('Tag','axes1');
axes(ax1);

to set the axes1 to the current axes. It works well. The second step, I show several images on the axes2,I use the code

ax2 = findobj('Tag','axes2');  
axes(ax2);

to set the axes2 to the current axes. It works well first time. When I repeat the second step, The error occurs, that is "Error using axes Invalid object handle,--axes(ax2);"

I am confused. Any suggestions?

Most likely, ax2 is empty, because that axes has been deleted … Remove the semi-colon to see if this is indeed the case:

ax2 = findobj('Tag','axes2')
