[Tm4j-developers] Deep Copy - ClassCastException

[Peri <per...@gm...>]

Hi,
I am trying to perform a copy from a TopicMap generated from in memory
provider  and populate my topicmap stored in the database.
While copying the scope bounded basenames, the copy operations errors out
with a class cast exception...


TopicMap:
topicmaps/kings_and_queens.xtm # Sample provided in the examples

Code Snippet:
TopicMapProvider provider_m = tmpf_m.newTopicMapProvider(providerProps);
Locator baseLocator_m = provider_m.getLocatorFactory().createLocator("URI",
getInputURI());

TopicMapSource src_m = new SerializedTopicMapSource(getInputStream(),
baseLocator_m);

// Parse the topic map
TopicMap tm_m = provider_m.addTopicMap(src_m);

TopicMapProvider provider_h = tmpf_h.newTopicMapProvider(providerProps);
Locator baseLocator_h = provider_h.getLocatorFactory().createLocator("URI",
getInputURI());

TopicMap tm_h = provider_h.getTopicMap(baseLocator_h);
provider_h.removeTopicMap(tm_h);
tm_h = provider_h.createTopicMap(baseLocator_h);

// Perform a copy
tm_h.getFactory().copy(tm_m);
