Hi,
I tried to switch from oaw to xtext. So I did the changes explained in
reference manual and now the syntax of my xtext grammar seems o.k.
When I started the workflow I got many warnings (-> Decision can match
input such as "'XYZ'" using multiple alternatives: 1, 2 As a result,
alternative(s) 2 were disabled for that input ...)
Than, I found a forum thread
( http://www.eclipse.org/newsportal/article.php?id=1240&gr oup=eclipse.modeling.tmf#1240)
with the advice of enabling backtracking.
I changed the following in my workflow -> here are the relevant code
fragments:
<!--<fragment class="org.eclipse.xtext.generator.AntlrDelegatingFragment"
/>-->
<fragment class="de.itemis.xtext.antlr.XtextAntlrGeneratorFragment">
<options backtrack="true"/>
</fragment>
AND
<!-- the following fragment tries to use the Antlr based content assist
fragment which can be downloaded from http://www.itemis.com
and will be ignored if it's not available. -->
<!-- <fragment
class="org.eclipse.xtext.generator.DelegatingGeneratorFragment "
delegate="de.itemis.xtext.antlr.XtextAntlrUiGeneratorFragment "
message="You are generating without ANTLR. It is highly recommended to
download and use the plugin 'de.itemis.xtext.antlr' \n\t using the update
site http://download.itemis.com/updates/milestones.">
</fragment> -->
<!-- <fragment
class="de.itemis.xtext.antlr.XtextAntlrUiGeneratorFragment"/ > -->
<fragment class="de.itemis.xtext.antlr.XtextAntlrUiGeneratorFragment" >
<options backtrack="true"/>
</fragment>
But now I get some errors like:
error(114):
../tfact.dsl/src-gen/com/tfact/parser/antlr/internal/Interna lTfactDsl.g:6370:3:
attribute is not a token, parameter, or return value: current
...
Can anybody of you give me a hint what's wrong?
TIA
Martin
