Ignition 8.0.4-NIGHTLY - 21/08/2019

@awalker, could you please fill a ticket for this bug:

I have some working binding in 7.9.X After upgrading to 8.0.4, when I open the windows I have the following error message:

Error writing "22/08/2019 00:00" to tag [replay]CommandTags/startDate Bad

The tag binded is a Memory DateTime exposed from a Managed tag Provider

does anybody hit or reproduce this bug in 8.0.4-Nightly ???

@mgross, @PGriffith, I suppose it is relative to DateTime datatype in the Tag managed Provider ?

In the script console, if I test a write, I have an error too :

import system
path = "[replay]CommandTags/startDate"
now = system.date.now()
system.tag.writeBlocking([path],[now])

return

[Bad]

In the module that create the Managed Tag provider with the tag :

this.ourProvider.configureTag(STATUS_TAG_START_DATE, DataType.DateTime);
...
MyWriteHandler myWriteHandler = new MyWriteHandler();
this.ourProvider.registerWriteHandler(COMMAND_TAG_START_DATE, myWriteHandler);

    protected class MyWriteHandler implements WriteHandler {

        @Override
        public synchronized QualityCode write(TagPath target, Object value) {
            try {
                if (tagPath.equalsIgnoreCase(COMMAND_TAG_START_DATE)) {
                    updateValue(COMMAND_TAG_START_DATE, value);
                    startDate = (Date) value;
                }
                return QualityCode.Good;
            } catch (Exception e) {
                logger.error("WriteHandler() - Exception : ", e);
                return QualityCode.Bad;
            }
        }
    }

The module works in 7.9 but in 8.0.4, DateTime exposed doesn’t works !

in the gateway, the error :

It seem I have the issue for all the tags,

the value seem to be a Qualified value in 8.0 instead of simple value like in 7.9

The following Interface WriteHandler is still ok ?

I think I found the source of this issue.

In the following Interface WriteHandler :

com.inductiveautomation.ignition.gateway.tags.managed.write​(TagPath target, java.lang.Object value)

the value seem to be a Qualified value in 8.0 instead of simple value like in 7.9

@PGriffith,@Kevin.Herron,
not sure the example for managedTagProvider still works without adding

value = ((QualifiedValue) value).getValue();

in :

            ourProvider.registerWriteHandler(CONTROL_TAG, (TagPath target, Object value) -> {
                Integer intVal = TypeUtilities.toInteger(value);
                //The adjustTags function will add/remove tags, AND update the current value of the control tag.
                adjustTags(intVal);
                return QualityCode.Good;
            });

@mazeyrat This is fixed in the 8.0.4 final.
