Actviti Modeler not working on Internet explorer

[ani123]

Hello
I have installed Activiti Explorer version 5.17. I cannot get the BPMN process modeler to work on Internet Explorer.
  I can see the BPMN editor, and can draw a BPMN diagram.
But when I try to save a Model which has connections  I get the following error, on model save
My question is
a) Is Activiti Modeler supported on Internet Explorer ?
b) If not what is the limiting factor, and can it be fixed  by the user?

Thanks for any pointers/help

Regards
Ani

Hello
Can anybody comment on this, when you get a chance?
  The issue I am seeing is coming from the apache.batik code, when it tries to save a model, which has connections in it.
  Any help is appreciated.

Thanks
Ani

[jbarrez]

a) yes, IE9+

What is the version of IE you are running it on?

[ani123]

I am using IE 11. I see the same issues with IE 9 and IE 10 too.

As mentioned,  the issue occurs only if there is a transition between two activitieis / event etc. If there are no transitions / sequence flows in the model, the model can be saved.

Thanks for any help. The stack trace does show the org.apcahe.batik throwing an exception. I am not sure if this is related to the
—-> arrow shape in the transition line being drawn.

Excuse me  if I am referring to an incorrect example. But several links on IE and SVG, do discuss issues with rendering of transitions, with a triangle/pointer head.  One such link is

http://stackoverflow.com/questions/15588478/internet-explorer-10-not-showing-svg-path-d3-js-graph

Though this one is slightly different: It does render the transition properly, but does not save  the model.

Any help is appreciated.

Best Regards
Ani

We are having the same issue.  I printed out the svgDOM generated from toolbar-default-actions.js:

<code>
        var svgDOM = DataManager.serialize(svgClone);
</code>

The first few lines of the result for a simple workflow with a start node, human task and end node are:

<code>
<svg xmlns="http://www.w3.org/2000/svg" xmlnsryx="http://oryx-editor.org" id="sid-318ECE9A-6742-4EF0-8124-DBA9D92054EC" width="433" height="159" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:svg="http://www.w3.org/2000/svg"><defs><marker id="sid-1A91CA7E-4FB9-492B-BD2A-920C1E872F7Dstart" refX="1" refY="5" markerUnits="userSpaceOnUse" markerWidth="17" markerHeight="11" orient="auto">
     undefined
   <path id="sid-1A91CA7E-4FB9-492B-BD2A-920C1E872F7Ddefault" display="none" fill="white" stroke="#585858" stroke-width="1" d="M 5 0 L 11 10"/>
</code>

As you can see there is "undefined" just before the path tag so I'm wondering if this is the cause of the issue.

Actually there is another "undefined" in the string:

<code>

The undefined text is not the issue.  I eliminated those from the string and still get the same error.

HI Jim
Thanks for your comment. So this does look like an issue with IE .
  This is kind of blocking me , we are looking as Activiti as one of the options for process modeling.
Will wait for further comments , and hopefully can have a workaround/ solution.

Best Regards
Ani

[jrnorrisjr]

Hi Ani,

This is blocking us too as one of our clients only uses IE (currently IE11).  If we find any solution I will post it here.

Jim

[ani123]

Thanks Jim
Do you think it is a bug in IE in the way it handles SVG?
Activiti does claim IE 9+ is supported. So this is surprising , that nobody has reported this earlier. Or may be not too many people  use Acitiviti on IE.
