<p>Hi all, I think I found a bug in the TableLayout when used in connection with #disableLayout.</p>
<p><br>
</p>
<p><b>Example to reproduce:</b></p>
<span style="font-size: 12pt">m := Morph new.</span><br>
<span style="font-size: 12pt">m</span><br>
<span style="font-size: 12pt;white-space: pre"></span><span style="font-size: 12pt">changeTableLayout;</span><br>
<span style="font-size: 12pt;white-space: pre"></span><span style="font-size: 12pt">listDirection: #rightToLeft;</span><br>
<span style="font-size: 12pt;white-space: pre"></span><span style="font-size: 12pt">wrapCentering: #center.</span><br>
<span style="font-size: 12pt">n := Morph new color: Color red.</span><br>
<span style="font-size: 12pt">n</span><br>
<span style="font-size: 12pt;white-space: pre"></span><span style="font-size: 12pt">visible: false;</span><br>
<span style="font-size: 12pt;white-space: pre"></span><span style="font-size: 12pt">disableLayout: true.</span><br>
<span style="font-size: 12pt">m addMorph: n.</span><br>
<p>
<div>m fullBounds.</div>
<p>
<p><b><br>
</b></p>
<p>
<div><b></b></div>
<b>Expected output:</b>
<p>
<p>Same as [n fullBounds].</p>
<p><br>
</p>
<p><b>Actual output:</b></p>
<p>Error: subscript is out of bounds: 1 in <span>TableLayout >> #computeExtraSpacing:in:horizontal:target:</span><b></b><br>
</p>
<p><span><br>
</span></p>
<p><span><b>Problem:</b></span></p>
<p><span>arrangement is nil.</span></p>
<p><span>In <span>#layout:in:, cells is <span>0@0->#(). This is an invalid state, isn't it?</span></span></span></p>
<p><span><span><span>The bug could have occurred because the initial <span>#hasSubmorphs check in #layout:in: does not work if the only submorphs have #disableLayout set.</span></span></span></span></p>
<p>Would it be an appropriate solution to exit the method after step 1, if cells value isEmpty?</p>
<p><br>
</p>
<p>I never have worked with LayoutPolicies in detail, thus I likely only see a small part of the problem. I also don't see why listDirection #leftToRight is handled fundamentally differently than #rightToLeft. Any help is appreciated! :-)</p>

<p>Best,</p>
