typeError: r is null

[kant1981]

Hi,

I have met a tough problem. I have one bpmn xml file which can be rendered by camunda-bpmn.js vey well, HOWEVER, another bpmn xml file which is generated from the same model but with a different version of parser, can not be rendered and in firebug it shows the error "typeError: r is null".

After roughly analysing the two xml files, I find that in the first xml file it contains only <dataObject> but in the second xml file it contains both <dataObject> and <dataObjectReference>. Is that where the error occurs?

Here is another difference.

There is one serviceTask and I copy the xml pieces here. I am not sure if here is where the problem happens.

the xml file which can not be rendered is shown below.

<serviceTask activiti:async="true" activiti:class="com.oneandone.coredev.swistec.psi.binding.activiti.ExecuteServiceAdapterDelegate" completionQuantity="1" id="PSItaskeventmerger" isForCompensation="false" name="PSI task event merger" startQuantity="1" uipcpmeta:originType="task">

where you can see like <ioSpecification> and <inputSet> are not shown in the xml piece below.

the xml file which can be rendered is shown below.

Hi kant1981,

this seems to be a Bug / Limitation whatever you might call it :)

Thanks for reporting. Could you maybe provide the stacktrace of the error?

...t){var n=e.getStyle(),r=e.getBounds(),s=+r.x,a=+r.y,f=+r.width,l=+r.height,c=o[e...

here is where the shit happens

[kant1981]

if you want, I can attach the whole xml, then you can do a complete analysis on the problem.

[kant1981]

By the way, I have found another small problem on this js, that if the name of a task contains one or more full stop, then this task can not be annotated. Should I open a new issue for that, or?
