Joram, can you check if we should delegate this to Signavio?

The issue is not Signavio related, but something that I introduced:

When the Modeler boots, it looks for a 'model-folder' in which the processes are stored.
In the past, I tried to look this folder up with '../../../activiti-model-repository' (or something like that),
but that doesnt seem to work.

So what happens now, is that when the demo is unzipped, the current path is matched with a regular expression. It then looks for something 'activiti-5.*'.

This means that, if you unzip the distribution as-is, there is no problem. However, when you unzip it to another folder nam (say 'MyActivitiTryout'), the regular expression fails and the Modeler doesnt boot.

By the way, this is the code that is the culprit:

(file in Signavio = FsPlatformPropertiesImpl)

private final String rootDirectoryPath;
private static final Pattern REPO_DIR_PATTERN = Pattern.compile(".activiti./apps/");
private static final String REPO_DIR = "activiti-model-repository/";

public FsPlatformPropertiesImpl(ServletContext context) {
serverName = context.getInitParameter("server");
platformUri = context.getContextPath() + "/p";
explorerUri = context.getInitParameter("explorer");
editorUri = context.getInitParameter("editor");
libsUri = context.getInitParameter("libs");
supportedBrowserEditor = context.getInitParameter("supportedBrowserEditor");

isTestSystem = Boolean.parseBoolean(context.getInitParameter("isTestSystem"));

String tempRootDirectoryPath = context.getInitParameter("fileSystemRootDirectory");

// Default : absolute repo path is given
if (tempRootDirectoryPath != null) {

if (tempRootDirectoryPath.endsWith(File.separator)) { rootDirectoryPath = tempRootDirectoryPath.substring(0, tempRootDirectoryPath.length()-1); } else { rootDirectoryPath = tempRootDirectoryPath; }

} else { // Alternative: a regexp that matches the current directory, // to which a given param is added String currentPath = context.getRealPath("/").replace("\\", "/"); Matcher matcher = REPO_DIR_PATTERN.matcher(currentPath); matcher.find(); rootDirectoryPath = matcher.group() + REPO_DIR; }

}

So what is your proposal on how we should deal with this? How urgent would you rank this?

See also ACT-143 (I am not sure if there is a connection).

Currently, The Modeler is unable to work with relative paths (eg ../../model-repo), so I implemented a workaround that updates the modeler war during the demo setup.

I also documented how to change the model repository when you want to run it on other containers, hosts and repository locations.
