#48 Error(s) while opening diagram from file

[Frank]

Just downloaded Violet version 0.21.1. Noticed that reopening an earlier created diagram results in exception (displayed in the bomb dialog):

com.horstmann.violet.framework.diagram.BentStyle not compatible with com.horstmann.violet.framework.diagram.Graph

- or -

com.horstmann.violet.framework.diagram.ArrowHead not compatible with com.horstmann.violet.framework.diagram.Graph

The diagram will not open. This can partly be worked around by opening the diagram file in a text- or xml editor and remove/comment all <object class="com.horstmann.violet.ArrowHead" ... /> and <object class="com.horstmann.violet.BentStyle" ... /> enties. Now the diagram will open in Violet again, but all line bends and arrowheads on the associations will be lost (ofcourse).

I'm experiencing this as well, with identical symptoms and (lossy) workaround.

I was able to manually edit the XML to display correctly as follows:

1) Find the following properties near the end of the file (multiple instances):

<void property="bentStyle">
</void>
<void property="endArrowHead">
</void>
<void property="lineStyle">
</void>

2) Fill in the properties as follows:

<void property="bentStyle">
<object class="com.horstmann.violet.BentStyle" field="VHV"/>
</void>
<void property="endArrowHead">
<object class="com.horstmann.violet.ArrowHead" field="TRIANGLE"/>
</void>
<void property="lineStyle">
<object class="com.horstmann.violet.ArrowHead" field="DOTTED"/>
</void>

Your actual values may (will) be different; they should mirror the corresponding values in the <object> tag near the top of the file.
