Example 1 with IPV

use of org.yamcs.studio.data.IPV in project yamcs-studio by yamcs.

the class AbstractScriptStore method init.

private void init() throws Exception {
    if (!(scriptData instanceof RuleScriptData) && !scriptData.isEmbedded()) {
        absoluteScriptPath = scriptData.getPath();
        if (!absoluteScriptPath.isAbsolute()) {
            // The following looked like this:
            // absoluteScriptPath = ResourceUtil.buildAbsolutePath(
            // editpart.getWidgetModel(), absoluteScriptPath);
            // .. but that doesn't work when the editpart is already a LinkingContainer.
            // It would fetch the parent's DisplayModel, i.e. look for scripts where the container is used,
            // instead of where it's defined.
            // 
            // After updating buildAbsolutePath() to handle (editpart instanceof LinkingContainer) as below,
            // the resolution of related displays failed again as in #977 because buildAbsolutePath() is
            // called in many placed while reading the *.opi file, and it would now build a different widget tree.
            // 
            // The following just fixes the relative script lookup from linking containers for #998,
            // without disturbing any other code.
            // 
            // TODO Understand & redo the whole widget model and its quirks for linking containers,
            // so all the recently added (.. instanceof ..Linking..) can be removed.
