JavaScript interpreter issues and frozen Text Areas due to HTML errors

JavaScript interpreter issues and frozen Text Areas due to HTML errors

Description: The JavaScript script interpreter in Spotfire utilizes a web browser component to render the Text Area HTML and JavaScript content. Fatal user made errors inside the HTML and JavaScript code will halt the execution of this component. When this happens, any Text Area in the analysis will be blanked and no longer respond to user interaction. This will persist even after the analysis is reloaded.

Resolution: To address any interpreter issues. the faulty code must either be modified or removed completely.

How to recover the analysis.

1). Open the script editor from the menu. [Edit > Document Properties > Scripts > JavaScript]. Remove or change any faulty scripts.

2). Save the analysis file.

3). Reopen the analysis file.

Sometimes script errors only halt the JavaScript interpreter. When this happens the Text Area content is still displayed as normal but the scripts will no longer execute. In this case, simply fix the script, save and reload the analysis to restart the script interpreter.
