Engine control not running in Eclipse using java 1.7

Philip Welch — Wed, 21 Nov 2012 09:46:37 -0000

Got the latest code off the SVN. Built the engine in Eclipse. Tried running engine control centre (CCMain.main) with default eclipse settings which had compiler compliance level set to 1.7. Unsupported class version exception.

[Editor] invalid binding on input-composite

David Karnok — Mon, 21 Nov 2011 18:00:58 -0000

1.) Create a new empty flow
2.) Have an input and output of the global flow
3.) Create a composite block
4.) Bind the outer input to the composite input, bind the inner composite output to the outer composite output

The generated XML doesn't contain the parameters in1 and out1 of the inner composite when mentioned in the bind:

<flow-description>
<composite-block id='flow-description-13' x='0' y='0'>
<input id='in2' displayname='in2' documentation='' type='advance:collection'>
<type-argument type-variable='T'/>
</input>
<input id='in' displayname='in' documentation='' type='advance:collection'>
<type-argument type-variable='T'/>
</input>
<output id='out' displayname='out' documentation='' type='advance:collection'>
<type-argument type-variable='T'/>
</output>
<composite-block id='composite1' x='61' y='358'>
<input id='in1' type='advance:collection'>
<type-argument type-variable='T'/>
</input>
<output id='out1' type='advance:collection'>
<type-argument type-variable='T'/>
</output>
</composite-block>
<bind id='bind1' source-parameter='in2' destination-block='composite1'/>
<bind id='bind2' source-block='composite1' destination-parameter='out'/>
</composite-block>
</flow-description>

The binding works with regular block.

The error message is misleading.

[Compiler] Ignores composite port types

David Karnok — Mon, 21 Nov 2011 17:54:04 -0000

The compiler doesn't add type relations of the composite block inputs and outputs: they behave as they wre simply of type variable T.
