Some background... Using Drools v5.3.5.Final and Guvnor v5.3.5.Final Created numerous packages, some of which contain assets that were promoted to "global" Some of the assets in "global" were placed there at the outset Assets that were placed in "global" at the outset are jar files for domain models used across multiple packages Assets that were promoted to "global" are functions that it turned out were needed in multiple packages The problem... For a subset of packages, any attempt to open a 'technical rule asset' in the Guvnor web interface results in the following pop-up error dialogs: /Unable to get content assistance for this rule./ *AND* /Unable to validate package configuration (eg, DSLs, models) for 'shipment.document.validation'. Suggestion completions may not operate correctly for graphical editors for this package./ Other possible information of interest, with regards to the packages that have the problem... Using JBoss Dev Studio, and its web-dav based interface, I can open the DRL files and they appear to be okay If I click on the link to download the source for the package, the resultant package file appears to contain everything as expected I am able to validate and compile the package, without error, from within Guvnor It should be noted that out of the nine packages I have defined, so far, only two of the packages exhibit this problem. In all of the other packages, I am able to manipulate technical rules via the Guvnor web-app. Summary... The primary problem is that I cannot use the rule editor within the Guvnor web-app to manipulate the rules. On the one hand, I'm not too concerned as JBDS seems to provide an adequate workaround. However, not being able to open the rules within the Guvnor application does seem to be a bit of a nuisance. -- View this message in context: http://drools.46999.n3.nabble.com/Error-when-I-try-to-open-technical-rule...
