Joint js rotation does not work properly with custom SVG elements - svg

Question

I am trying to use the rotate functionality which is proved by the Halo,
I have added an element into the stencil like this..
var customMarkup = ' <path id="path123" stroke="#000000" stroke-miterlimit="10" d="M7.2,28V15.7L20.3,4.1l9-0.6v8.8c0,0-9,5-9,8.6 c0,1.7,0,7.2,0,7.2H7.2z"/> <polyline id="polyline125" stroke="#000000"

var customElement = joint.shapes.basic.Image({

attrs: {
'text': { text: 'asdf' },
height: 500,
width: 100,
'.myClass': {
fill: '#ffffff'
}
}
})
The element looks fine on the Stencil and it looks good when i drag it and drop it onto the paper,
Now I would like to rotate it, and i am having a really hard time in trying to make it happen.
In case i resize the element and then try to rotate it.. and then resize it again all the transformations are completely messing up like in the image below..
I read an article and learn that the svg rotations are not similar to what is done in css so tried the following on click of a button but that did not help either.
My goal is to keep the custom SVG element within the halo when it rotates and not allow it to skew up
I also tried to do the rotation on the click of a button instead of using the Halo like as follows.. but does not help
jQuery('#btn-rotate').on('mousedown', _.bind(function (evt) {
var x = this.selection.models[0].attributes.position.x;
var y = this.selection.models[0].attributes.position.y
var height = this.selection.models[0].attributes.size.height;
var width = this.selection.models[0].attributes.size.width;
this.selection.models[0].rotate(93, [false, { x: x+width/2, y: y+height/2}]);
}, this));
Would really appreciate your help.
Thanks

Answer 1

It's not supported to nest the rotatable group into the scalable group in JointJS. The groups can be omitted (together or individually) or the scalable group can be a child of the rotatable group. Only the following schemes can be used.
<g class="rotatable"/><g class="scalable"></g></g>
<g class="rotatable"></g>
<g class="scalable"></g>
In your case the rotatable and the scalable group needs to be swapped.
<g class="rotatable"><g class="scalable"><g class="myClass"><!-- custom markup --></g></g></g><text/>
For more please see demo.
