Hi,
I get a NPE when uploading a file to the blob service in my local Eclipse
environment. Can anyone help me understand what I need to do to fix this
situation? Thanks.
I'm using App Engine 1.4.0.
My form:
<form target="FormPanel_prj_1" enctype="multipart/form-data" method="post"
action="/_ah/upload/aglub19hcHBfaWRyGwsSFV9fQmxvYlVwbG9hZFNlc3Npb25fXxgJDA">
<div class="gwt-Label ui-input-text">Description</div>
<input type="text" class="ui-input-text ui-corner-all
ui-shadow-inset ui-body-c" name="description">
<div class="gwt-Label">File</div>
<input type="file" class="gwt-FileUpload" name="file">
<input type="submit">
</form>
[WARN] /_ah/upload/aglub19hcHBfaWRyGwsSFV9fQmxvYlVwbG9hZFNlc3Npb25fXxgJDA
