Gurux DLMS for Java

When I load an association viw from disk (XML I dumped) I have noticed that in some cases date fields are empty, resulting in an ibject like:

<GXDLMSData>
<LN>0.0.96.2.13.255</LN>
<Description>Ch. 0 Date of last firmware activation</Description>
<Access>10</Access>
<MethodAccess></MethodAccess>
<Value Type="0" UIType="25"></Value>
</GXDLMSData>

Failing to parse with an error because the Value tag is empty. Is there a way for GuruX to parse these in a less strict way ike defaulting to a certain date possibly?

Hi,

I understand the problem but I don't have an answer on how to handle this yet. Value is empty if it's not read from the meter. I have two options at the moment.

a. Value tag is not written at all if date-time is not read.
b. Epoch time (Jan 01 01:00:00 GMT 1970) is written.

At the moment I believe that option a is better, but I need to think that this is not break anything.

Hi,

Are you using GXDLMSObjectCollection.load method to load this? Something like this or are you parsing it by yourself?

GXDLMSObjectCollection items = GXDLMSObjectCollection.load("file.xml");
