    <p>i've a nasty problem with my TreePanel: i use a TreeLoader to get data from an url. An example tree is correctly rendered in my panel so the problem should be in the custom data. I get my data through a python cgi which builds step by step the string to write. This is the TreePanel code:</p> <pre><code>var Tree = Ext.tree; var tree = new Tree.TreePanel({ useArrows: true, autoScroll: true, animate: true, enableDD: true, containerScroll: true, border: false, // auto create TreeLoader dataUrl: '../python/tree/get_tree', root: { nodeType: 'async', text: '369', } }); </code></pre> <p>The Data written by the python cgi is the following:</p> <pre><code> [{ id: 476, text: 'memShared', leaf: true },{ id: 477, text: 'icmpInParmProbs', leaf: true },{ id: 478, text: 'memTotalFree', leaf: true },{ id: 479, text: 'icmpOutEchos', leaf: true },{ id: 480, text: 'memAvailReal', leaf: true },{ id: 481, text: 'icmpInAddrMaskReps', leaf: true },{ id: 482, text: 'icmpInRedirects', leaf: true },{ id: 483, text: 'loadavg1', leaf: true },{ id: 484, text: 'tcpCurrEsta', leaf: true },{ id: 485, text: 'icmpInErrors', leaf: true },{ id: 486, text: 'icmpInMsgs', leaf: true },{ id: 498, text: 'icmpInTimeExcds', leaf: true },{ id: 499, text: 'tcpActiveOpens', leaf: true },{ id: 500, text: 'eCpuRawNice', leaf: true },{ id: 512, text: 'icmpOutTimeExcds', leaf: true },{ id: 513, text: 'icmpInEchos', leaf: true },{ id: 514, text: 'memBuffe', leaf: true },{ id: 515, text: 'icmpInSrcQuenchs', leaf: true },{ id: 516, text: 'icmpOutErrors', leaf: true },{ id: 517, text: 'tcpAttemptFails', leaf: true },{ id: 518, text: 'icmpOutAddrMaskReps', leaf: true },{ id: 519, text: 'tcpOutSegs', leaf: true },{ id: 520, text: 'loadavg15', leaf: true },{ id: 521, text: 'tcpRetransSegs', leaf: true },{ id: 522, text: 'tcpEstabResets', leaf: true },{ id: 523, text: 'icmpOutTimestamps', leaf: true },{ id: 524, text: 'memTotalReal', leaf: true },{ id: 525, text: 'icmpOutTimestmpReps', leaf: true },{ id: 526, text: 'icmpOutDestUnreachs', leaf: true },{ id: 527, text: 'tcpPassiveOpens', leaf: true },{ id: 528, text: 'memTotalSwap', leaf: true },{ id: 529, text: 'tcpInSegs', leaf: true },{ id: 530, text: 'icmpOutSrcQuenchs', leaf: true },{ id: 531, text: 'icmpInTimestampReps', leaf: true },{ id: 532, text: 'icmpOutEchoReps', leaf: true },{ id: 533, text: 'tcpOutRsts', leaf: true },{ id: 534, text: 'icmpInAddrMasks', leaf: true },{ id: 535, text: 'memSwapErro', leaf: true },{ id: 536, text: 'eCpuRawIdle', leaf: true },{ id: 537, text: 'eCpuRawKernel', leaf: true },{ id: 538, text: 'memAvailSwap', leaf: true },{ id: 539, text: 'tcpInErrors', leaf: true },{ id: 540, text: 'icmpOutAddrMasks', leaf: true },{ id: 541, text: 'icmpOutRedirects', leaf: true },{ id: 542, text: 'eCpuRawSystem', leaf: true },{ id: 543, text: 'eCpuRawInterrupt', leaf: true },{ id: 544, text: 'icmpOutMsgs', leaf: true },{ id: 545, text: 'icmpInTimestamps', leaf: true },{ id: 546, text: 'icmpInEchoReps', leaf: true },{ id: 547, text: 'eCpuRawWait', leaf: true },{ id: 548, text: 'eCpuRawUse', leaf: true },{ id: 549, text: 'memCached', leaf: true },{ id: 550, text: 'loadavg5', leaf: true },{ id: 551, text: 'icmpInDestUnreachs', leaf: true },{ id: 552, text: 'icmpOutParmProbs', leaf: true },{ id: 501, text: e, children: [{ id: 502, text: 'ifInOctets', leaf: true },{ id: 503, text: 'ifOutUcastPkts', leaf: true },{ id: 504, text: 'ifOutNUcastPkts', leaf: true },{ id: 505, text: 'ifInDiscards', leaf: true },{ id: 506, text: 'ifOutDiscards', leaf: true },{ id: 507, text: 'ifInErrors', leaf: true },{ id: 508, text: 'ifOutOctets', leaf: true },{ id: 509, text: 'ifOutErrors', leaf: true },{ id: 510, text: 'ifInUcastpkts', leaf: true },{ id: 511, text: 'ifInNUcastpkts', leaf: true }]},{ id: 487, text: 'dskIndex', children: [{ id: 488, text: '('1',)', children : [{ id: 489, text: 'ns-dskUsed', leaf: true },{ id: 490, text: 'ns-dskPercent', leaf: true },{ id: 491, text: 'ns-dskAvail', leaf: true },{ id: 492, text: 'ns-dskTotal', leaf: true }]},{ id: 493, text: '('2',)', children : [{ id: 494, text: 'ns-dskUsed', leaf: true },{ id: 495, text: 'ns-dskPercent', leaf: true },{ id: 496, text: 'ns-dskAvail', leaf: true },{ id: 497, text: 'ns-dskTotal', leaf: true }]}]}] </code></pre> <p>I can't figure out what the problem is, parenthesis should be correctly balanced and firebug doesn't raise any error. Is this string not well formed? Or is there another way which makes my treepanel not working? Thank you very much for any help provided!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
